IoT Firmware Security and Update Mechanisms: A Deep Dive

The use of network connected Internet of Things (IoT) devices is growing rapidly, introducing various cybersecurity and supply chain attacks targeting these endpoints. Real-world attacks have shown how firmware can be exploited to create botnets, steal data, or even take control of critical infrastructure. The infamous Mirai botnet, for example, leveraged insecure IoT devices to launch massive DDoS attacks. Many of those devices had hardcoded credentials and no way to update their firmware. 

Due to this, keeping the firmware of your IoT devices up to date becomes a crucial aspect of your cybersecurity posture. Firmware updates are crucial to fix software bugs, patch vulnerabilities, or add new security features. Equally important is ensuring these updates are secure and trusted.  

Key challenges with IoT firmware Security 

Securing firmware is not as straightforward as securing a web application. IoT devices are often resource-constrained, meaning they don’t have the processing power or memory to support traditional security protocols. They’re also incredibly diverse—different chipsets, different operating systems, different update mechanisms. This lack of standardization makes it hard to apply a one-size-fits-all solution. 

Supply chains vulnerability is a key challenge for firmware security as firmware is often developed by third-party vendors or assembled from open-source components. This opens the door to tampering long before the device reaches the end user. And once it’s out in the field, updating that firmware becomes a logistical nightmare, unless you’ve planned for it from the start. 

Additionally, unauthorized access to code-signing keys or firmware signing mechanisms allows attackers to impersonate trust and deliver malicious updates to devices that appear trusted. 

Finally, insecure coding practices could allow attackers to exploit buffer overflows to gain remote access to devices and create DDoS or malware-injection attacks.  

Consequences of insecure IoT firmware 

Insecure IoT firmware could lead to various attacks that could be employed remotely by an attacker without warning. Let’s look at some of the examples below:  

In September 2016, the creators of Mirai launched a DDoS attack on the website of a well-known security expert. Shortly after, they released the source code, which was quickly adopted by other cybercriminals. This led to a massive attack on the domain registration services provider, Dyn, in October 2016, causing widespread disruption.
The RIFT botnet emerged in December 2018 using a variety of exploits to infect IoT devices. According to online sources, the botnet used 17 exploits. 
On December 11, 2018, a remote code execution vulnerability in the ThinkPHP framework was reported wherein the OS commands were injected through the query parameter “vars”. This follows a typical exploitation sequence observed in RIFT attacks.
In another incident, D-Link accidentally leaked private code-signing keys used to sign software. While it’s not known whether the keys were used by malicious third parties, the possibility exists that they could have been used by a hacker to sign malware, making it much easier to execute attacks.
In one of the attacks on connected cars, researchers at the Chinese firm Tencent revealed they could burrow through the Wi-Fi connection of a Tesla S all the way to its driving systems and remotely activate the moving vehicle’s brakes.

Securing IoT firmware updates – Vendors’ perspective

Over-the-air (OTA) updates allow you to push firmware patches, security fixes, and even new features to devices remotely without the need for any physical access. OTA updates are usually delivered through cellular data (4G or 5G) or through internet connections. 

OTA not only brings convenience to your firmware update process but also adds resiliency providing your organization with crypto agility in dealing with any kind of cyberattack. Without OTA, you’re stuck with whatever firmware was on the device at launch. And if that firmware has a flaw, you’re in trouble. 

Designing a secure OTA system is crucial to ensure firmware security. Every update should be signed with a private key and verified on the device using a corresponding public key. This ensures that only trusted updates are installed. Devices should reject any update that doesn’t meet these criteria. The update process should also include integrity checks to prevent tampering during transmission. Also, a rollback protection is crucial to ensure that the attackers shouldn’t be able to downgrade firmware to a vulnerable version. 

Equally important is the infrastructure behind the updates. You need a secure server environment to host the firmware, a reliable delivery mechanism, and a monitoring system to track update success rates and failures. User transparency is important as well for keeping your users informed when updates are happening and why, building trust and reducing resistance. 

Securing IoT firmware updates – End User’s perspective 

Insecure IoT firmware updates could cause serious consequences for the users of these devices especially because any kind of malicious attacks can be done remotely without requiring any physical access to the device.  

To safeguard against insecure firmware updates, avoid automatic updates specially on untrusted networks and only get the updates from the vendor’s secure website using HTTPS.  Also, always consider prioritizing firmware support in your purchase decisions. 

Real-World Applications, Standards and Innovations in firmware security 

Industries that rely heavily on IoT, like automotive, healthcare, and manufacturing sectors, are already seeing the benefits of secure OTA updates. In the automotive sector, for example, OTA updates are used not just for infotainment systems but for critical safety features. Tesla famously uses OTA to roll out everything from performance improvements to bug fixes, often overnight. 

In healthcare, where devices like insulin pumps and heart monitors are increasingly connected, OTA updates can be a matter of life and death. A vulnerability in a medical device isn’t just a security issue, it’s a patient safety issue. Secure OTA mechanisms ensure that these devices can be updated quickly and safely, without requiring a hospital visit. 

Standards like NIST’s IoT cybersecurity framework and ETSI EN 303 645, are pushing IoT manufacturers towards adopting secure development practices, rigorous testing, and a robust OTA infrastructure. 

Recent research has proposed advanced cryptographic techniques to secure firmware updates against supply chain attacks. For example, post-quantum cryptography (PQC) methods like Dilithium and SPHINCS+ are being explored to ensure firmware authenticity and integrity in a quantum-resilient manner.

Conclusion 

Firmware may be invisible to most users, but it’s the backbone of every IoT device. Investing in secure firmware practices and robust OTA update systems is the key to safeguarding and mitigating the risks associated with firmware vulnerabilities and cryptographic attacks. 

Homomorphic Encryption – Enabling Secure Computations on Encrypted Data

Homomorphic encryption (HE) is an advanced cryptographic technique that allows data to remain encrypted even while it is being processed. In other words, a server can perform computations on ciphertexts, and the decrypted result matches the operation on the original plaintext. For example, one recent description explains that HE “enables calculations to be carried out on encrypted data”, producing an encrypted outcome that aligns with the computation on the raw data. This property enables cloud services or third parties process sensitive data (e.g., analytics, AI/ML tasks) without ever seeing the unencrypted data.

In practice, the client generates a key pair (public and private) and an evaluation key. The public key is used to encrypt the data, and the evaluation key is given to the server to perform arithmetic on ciphertexts. The server never sees plaintext; it only returns an encrypted result. Finally, the client uses the private key to decrypt the outcome. Because HE “supports arbitrary computations on encrypted inputs”, it preserves data confidentiality end-to-end. As it is mentioned in ISACA white paper, HE “can be used to obtain insights from computation without revealing the contents of a dataset” and it keeps personal data encrypted “at rest, in transit, and during computation”.

What are the implementation strategies for Homomorphic Encryption

HE comes in three main implementation architectures, differing in what operations they allow on ciphertexts:

Partially Homomorphic Encryption (PHE): Supports one kind of operation (either addition or multiplication) on ciphertexts an unlimited number of times. Classic examples include RSA or Paillier for adding encrypted values.
Somewhat Homomorphic Encryption (SHE): Supports both addition and multiplication but only for a limited number of total operations before the ciphertext noise grows too large.
Fully Homomorphic Encryption (FHE): Supports arbitrary circuits any combination of additions and multiplications (and thus any computable function). FHE enables unlimited chained operations on encrypted data.

The choice of architecture depends on the use case: PHE is simplest and fastest when only one operation is needed; SHE allows more flexibility but still limits complexity; FHE is the most powerful (truly general-purpose) but also the most complex. An authoritative ENISA report notes that FHE “has good protection and utility but poor performance,” reflecting this trade-off.

How Homomorphic Encryption Works

HE is typically based on lattice-based cryptography, such as learning with errors (LWE) or related problems. Modern FHE schemes (e.g., BFV, BGV, CKKS) use ring-LWE and number-theoretic transforms. These constructions conceal the data in structured, high-dimensional “noise” patterns, which are challenging for classical or even quantum computers to decipher. Lattice-based schemes used by FHE are considered post-quantum secure.

Homomorphic Encryption process — Homomorphic Encryption

A Typical HE computation workflow looks like this:

Encryption: The client encodes data into polynomials, encrypts it with a Ring-LWE-based scheme, and sends it to the server.
Computation: The server performs additions and multiplications on ciphertexts, using NTT for efficiency and managing noise growth.
Decryption: The client decrypts the result using the private key, recovering the computed output.

HE systems introduce a small amount of noise with each homomorphic operation; therefore, schemes must include a bootstrapping step to “refresh” ciphertexts or utilize built-in noise management. The net result is that an FHE system correctly performs the same computation as if it were done on plaintext. In practice, evaluation requires specialized software libraries, such as Microsoft SEAL, IBM HElib, PALISADE, and TFHE, or even hardware accelerators. For example, the Cloud Security Alliance (CSA) notes that as HE technology and hardware improve, FHE “is likely to become a ubiquitous information security tool” that encrypts data during all stages of use.

Emerging footprints of encrypted processing in the industry

Homomorphic encryption is still an emerging technology, but several sectors are actively exploring it for privacy-preserving analytics:

Finance: In the finance sector, banks and fintech companies manage highly sensitive customer information, such as transaction records and risk profiles. HE allows these organizations to perform analytics—like fraud detection and credit scoring—on encrypted data. IBM researchers, for instance, demonstrated encrypted machine learning (ML) on banking data with accuracy matching the unencrypted baseline. HE can also secure credit scoring or fraud detection by keeping all account data encrypted in a public cloud.
Healthcare and Genomics: Healthcare providers and researchers often need to analyze patient data such as electronic health records (EHRs) or genomic sequences, across multiple institutions without compromising patient privacy. HE enables this collaboration by allowing computations on encrypted records. For example, in 2019, Duality Technologies, Inc. and the Dana-Farber Cancer Institute collaborated to apply homomorphic encryption (HE) in the healthcare domain. The initiative focused on enabling secure, large-scale genome-wide association studies by analyzing multisourced, encrypted data without ever decrypting it, preserving privacy while advancing medical research. An AHIMA report highlights FHE’s promise for cross-institution data analytics in healthcare. This makes HE a critical tool for secure, AI-driven healthcare analytics.
Cloud Computing and SaaS: Any cloud-deployed computation (analytics, AI, databases) can, in principle, run on encrypted inputs. HE is revolutionizing cloud computing by enabling secure data processing in untrusted environments. A typical use case involves a client encrypting their data locally, uploading it to a cloud service, and receiving encrypted results after computation, all without the cloud provider accessing the plaintext. The cloud never decrypts the data; instead, it returns an encrypted result. As one IEEE source explains, this means “cloud providers will never have access to the unencrypted data they store and compute on,” making HE ideal for public cloud environments. This is particularly valuable for software-as-a-service (SaaS) platforms handling sensitive data, offering a new level of privacy in public cloud deployments.
IoT and Edge Computing: With billions of IoT devices collecting personal data (such as health monitors, smart homes, and connected cars), HE can help secure data-in-use at the edge. For example, proposals for “quantum-resistant homomorphic encryption for IoT” show that FHE can encrypt sensor data to run analytics without revealing user identity. Although such systems incur extra computational cost, they demonstrate HE’s potential for secure edge-cloud processing in the quantum era.
Elections and Voting: FHE can enable end-to-end verifiable elections by allowing vote tallying on encrypted ballots. Microsoft’s ElectionGuard utilizes HE to count votes without decrypting individual ballots, ensuring that votes remain secret while results are provably correct. This approach has been cited as a way to achieve “end-to-end verifiable elections” without exposing voter choices.
Data Marketplaces and Outsourced Computation: Companies may sell the ability to query their data without revealing it. For instance, a search engine could compare encrypted queries against an encrypted index, returning results without seeing the query in plaintext. Financial and insurance industries also consider HE for privacy-preserving data sharing and model training.

The Cloud Security Alliance (CSA) working group summary specifically highlights finance, healthcare, and government as fields where cryptographic protection during processing is highly desirable. Many of these use cases are still under development or in the research and prototype stages, but they illustrate the broad potential of encrypted computation.

How Homomorphic Encryption ensures compliance with Regulatory Standards

Homomorphic encryption ensures secure data processing, aligning with GDPR, HIPAA, and PCI DSS by keeping data encrypted, reducing breach risks, and supporting NIST and ISO/IEC standards.

GDPR encourages strong data protection by design. While encrypted data is still “processing,” using HE can help satisfy security requirements. Notably, the European Data Protection Board (EDPB) guidelines on breach notification allow an exemption when data is rendered “unintelligible” by encryption. If HE ensures that leaked ciphertext cannot be decrypted by attackers (no key compromise), a breach of encrypted data “may not need to be notified”. However, legal analysts caution that homomorphic encryption itself is still considered a form of processing that requires a lawful basis under the GDPR.

In practice, HE is more often treated as a pseudonymization or encryption measure that reduces risk under GDPR. For example, experts note that HE’s encrypted data could be considered “de-identified” for certain regulatory purposes, as it’s not directly attributable to individuals without the keys. In short, HE ensures GDPR compliance by strengthening data security (Article 32: Security of Processing) and potentially easing breach liability; however, controllers must still maintain a valid consent or basis for processing, even when encrypting.

HIPAA (US Health Privacy Law)

Health Insurance Portability and Accountability Act (HIPAA) requires covered entities to protect electronic protected health information (ePHI) with “technical safeguards,” including encryption where reasonable. A detailed HIPAA analysis suggests that if PHI is encrypted with HE and the decryption key remains solely with the covered entity, that data could be treated as de-identified outside HIPAA’s scope.

Essentially, homomorphic encryption can serve as a form of encryption-based pseudonymization under the HIPAA. As long as the data remains encrypted and the key is secret, the risk of unauthorized disclosure is “very small,” potentially satisfying HIPAA’s standards. In practice, HE can help healthcare organizations comply with HIPAA by enabling the secure outsourcing of analytics on patient data without exposing raw PHI.

PCI DSS (Payment Card Industry)

PCI-DSS mandates strong encryption for cardholder data both at rest and in transit. While PCI-DSS does not explicitly discuss HE, homomorphic encryption can, in principle, enhance the security of card data. For example, a payment processor might run fraud detection algorithms on encrypted card data without decrypting it, further reducing exposure. As regulations evolve to emphasize end-to-end data protection, HE’s ability to keep sensitive fields encrypted during processing aligns well with PCI’s goals, as well as with newer privacy laws like CCPA.

NIST and ISO/IEC Standards

On the cryptography side, standardization efforts for HE are underway. NIST’s Cryptographic Standards and Guidelines (CSRC) recognizes HE as a “special type of encryption scheme” enabling evaluations on encrypted data. NIST has been actively organizing workshops, such as WPEC 2024, on Privacy-Enhancing Cryptography, which include sessions on Fully Homomorphic Encryption (FHE), use cases in health and finance, and performance guidelines.

Meanwhile, ISO/IEC has already published standards covering homomorphic encryption. For instance, ISO/IEC 18033-6:2019 specifies mechanisms for homomorphic encryption (e.g., Exponential ElGamal, Paillier). Additionally, HomomorphicEncryption.org, published a Homomorphic Encryption Security Standard in 2018 and continues to work on API/SDK standards. As one 2024 analysis notes, ISO is advancing FHE standardization “to support wider adoption” of these techniques.

Encryption is already a required control under GDPR, HIPAA, and PCI-DSS, and HE extends encryption into the computation phase. Regulatory and standards bodies are actively examining HE: GDPR guidelines implicitly treat encrypted data as lower-risk, HIPAA allows re-identification keys, and NIST/ISO are formalizing HE schemes. Organizations can leverage HE to strengthen “privacy by design” and demonstrate cutting-edge protection to regulators.

Industry Adoption Trends for Homomorphic Encryption and Market Growth

The adoption of homomorphic encryption is growing, driven by increasing demands for data privacy and the growing adoption of cloud services. While HE is still not ubiquitous in production systems, surveys and analyses indicate rising interest:

Market Size: Recent market research reports value the global HE market at a low of hundreds of millions of USD. For example, a 2024 report estimated the market at approximately $178.4 million in 2023, with an annual growth rate of around 8% into the early 2030s. Another analysis forecasted roughly $189.5M in 2022, growing to approximately $358.9M by 2030 (CAGR of ~8.3%). These figures reflect that HE is a niche but rapidly expanding segment of the data security market.
Sector Adoption: Certain sectors lead the way in HE exploration. Financial services, including banks and fintech, are keen on secure analytics and risk computation; CSA specifically highlights finance as a primary target for FHE adoption. Healthcare and biotech are also prominent, driven by secure genomic analysis and multi-hospital studies. Cloud service providers and tech companies are developing High-End (HE) capabilities, for example, IBM Research offers an “HE for Cloud” platform, and Microsoft’s SEAL library is widely utilized. Government and defense agencies are exploring HE for securing citizen data and intelligence analytics. In contrast, adoption in other industries, such as retail and manufacturing, is more experimental.
Benchmarks & Tools: Multiple open-source libraries now implement HE (e.g., Microsoft SEAL, Intel PALISADE, IBM HElib, CUFHE, TFHE, OpenFHE). Benchmark studies (such as “FHEBench” in 2022) are characterizing performance across schemes. These benchmarks highlight that different schemes trade off speed versus functionality: e.g., some schemes handle integer math efficiently, while others are optimized for bit operations. Overall, however, current HE operations remain orders of magnitude slower than plain computations. Most reports note that FHE is still “inefficient in practical settings”, with very high computing and memory costs.
Drivers and Barriers: Growth drivers include stricter privacy laws, data breach risks, and demand for cloud AI on sensitive data. For example, increasing ransomware and breaches (FBI reported over 2,285 ransomware complaints in 2023) motivate stronger in-use protections. HE is often positioned as a key part of “data protection by design.” Barriers include computational overhead, complexity of implementation, and the need for skilled cryptographers. Many implementations still require custom engineering. Performance remains the top hurdle: as one IEEE summary puts it, HE is “one of the most powerful” but also “still in an early phase” and not yet fast enough for general business use.

Despite challenges, analysts predict healthy growth. The continual maturation of HE (through academic research and startup efforts) is expected to widen its use. Cloud vendors, security firms, and open-source communities are all investing in making HE more practical. For example, start-ups like Zama and Duality are developing optimized FHE compilers and machine learning (ML) frameworks. These efforts, along with upcoming standards and hardware accelerators, suggest that adoption will gradually expand from niche pilots to broader applications. In the next few years, adoption trends are likely to follow an S-curve, with early adoption by high-privacy sectors (such as finance, healthcare, and government) and later spillover to other industries as performance improves.

Performance Challenges and Research Directions for Data Privacy

Fully homomorphic encryption is a powerful but computationally intensive technique. Every homomorphic operation on ciphertexts is much slower than the same plaintext operation. Common statements from experts include: “FHE schemes… are currently still inefficient in practical settings”. Real-world benchmarks reveal that simple operations, such as adding two 32-bit numbers, can take milliseconds or more, while bootstrapping (noise refresh) can require seconds on current hardware. This large overhead, often hundreds or thousands of times slower, is the main bottleneck.

Key research directions to overcome performance limits include:

Algorithmic Improvements: New FHE schemes and optimizations (e.g., CKKS for approximate arithmetic, TFHE for fast bootstrapping) continue to emerge. For instance, a 2024 study reports a new integer FHE construction that maintained ~98% accuracy over many operations with only modest additional cost compared to traditional methods. FHE compilers and frameworks (such as Concrete and OpenFHE) automatically optimize parameters and circuits for speed. In July 2024, Zama showed that its Concrete-ML compiler could “beat previous performance benchmarks” for encrypted neural network inference, demonstrating rapid progress in applying FHE to ML tasks.
Hardware Acceleration: Since HE is parallelizable at the bit or word level, it can benefit from the use of GPUs, FPGAs, or specialized hardware. Researchers are exploring FPGA and ASIC designs for fully homomorphic encryption (FHE). NIST PEC documents note talks on “FHE hardware performance” at recent workshops. For example, prototype chips implementing homomorphic operations have been reported in the literature, aiming to offload the costly computation of polynomial arithmetic. As one ENISA report notes, HE is a “balancing act,” and performance will improve as hardware and engineering catch up.
Noise Management and Bootstrapping: Bootstrapping (refreshing ciphertext noise) was once too costly for all but simple tasks, but new techniques are making it more practical. Some modern FHE schemes delay bootstrapping or use leveled FHE to reduce the need for frequent refresh. Ongoing work focuses on “programmable bootstrapping” and other techniques to make deep circuits feasible.
Standardization of Parameters: A unique challenge of FHE is selecting the correct security parameters (keys, moduli, noise budgets) for each application. The 2024 “Security Guidelines for Implementing FHE” paper reports that parameter selection is hard because it affects both security and allowed operations. Work like this aims to provide reference tables and toolkits that enable developers to select safe and efficient settings. HomomorphicEncryption.org and NIST are collaborating on such guidelines, which should accelerate safe adoption.

In summary, performance challenges continue to be the primary limitation of higher education (HE) today. However, active research in algorithms, hardware, and compiler tooling is closing the gap. Every year sees faster implementations: recent blog reports of practical encrypted inference show run-times improving significantly. As one expert concludes, FHE is “new and extremely powerful,” and as core technology improves, it will likely become ubiquitous.

Available Documentation and Industry Resources for Homomorphic Encryption

Several key publications and organizations provide detailed guidance on homomorphic encryption:

Standards and Guidelines: NIST’s Privacy-Enhancing Cryptography (PEC) project and HomomorphicEncryption.org (an industry consortium) have produced security standards and guidelines. Notably, the Homomorphic Encryption Security Standard (2018) describes the security of schemes and parameter sets. The ISO/IEC standards (ISO/IEC 18033-6:2019 and draft ISO/IEC 18033-8) formally specify homomorphic algorithms. In academia, recent papers (e.g., “Security Guidelines for Implementing FHE”, 2024) survey FHE schemes and propose standardized parameter sets.
Government Publications: EU and national data-protection bodies have acknowledged HE in privacy engineering reports. For example, a 2022 ENISA whitepaper on data protection engineering highlights HE as a privacy-enhancing technology and notes its trade-offs. Workshops like the EU’s Privacy-Enhancing Technologies conferences often include FHE in their agenda. In the U.S., NIST’s Cryptographic Technology Group is funding research, such as the PEC workshops, and may eventually include HE in future cryptographic guides.
Industry Whitepapers: Leading cybersecurity organizations and tech companies publish analyses and tutorials on HE. For instance, IEEE’s Digital Privacy portal has articles on HE advantages and use cases. Cloud Security Alliance provides working group materials on FHE in cloud security. Companies like IBM, Microsoft, Google, Duality, and Zama publish blog posts and whitepapers demonstrating HE techniques and benchmarks. These resources often include technical overviews and case studies.
Academic Surveys: Numerous academic surveys and conference papers exist on higher education (HE). (Given user instructions, we would cite some, but space is limited in a blog format.) Seminal works (such as Gentry’s 2009 construction) and subsequent improvements (e.g., Brakerski-Gentry-Vaikuntanathan schemes) are often referenced in crypto literature. IEEE and Springer journals have recent survey articles on HE in healthcare, finance, etc., which detail performance and security considerations.

These documentation sources emphasize that HE is at the cutting edge of privacy technology. As standards crystallize and more implementations emerge, these references will help organizations adopt HE correctly. Stakeholders should consult them for best practices, such as secure parameter choices and compliance guidance, when planning HE deployments.

Modern Strategies for Signing and Verifying Container Images with CodeSign Secure

Introduction

Software supply chain attacks aren’t just a theoretical risk anymore; they’re happening, and they’re hitting hard. Incidents like the SolarWinds breach and the Log4Shell vulnerability made it painfully clear that attackers are no longer just targeting your code; they’re going after everything that touches it, including the tools, libraries, and containers you rely on.

In this reality, signing and verifying container images isn’t a nice-to-have; it’s a must. If you’re pushing unsigned images or skipping signature checks during deployment, you’re leaving the door wide open for attackers to sneak in malicious code without you even noticing.

That’s where our CodeSign Secure comes in.

CodeSign Secure makes it easy to add digital signatures to your container images and verify them before they ever hit production. Whether you’re running a fast-moving CI/CD pipeline or managing hundreds of microservices, it helps you lock down your container supply chain without slowing anything down.

In the sections ahead, we’ll walk through how our CodeSign Secure fits into your workflow, how it secures your images with HSM-backed keys, and how you can enforce signature checks before anything gets deployed.

The Role of Code Signing in DevSecOps

DevOps is all about speed, pushing updates fast, automating everything, and keeping things moving. But with that speed comes risk. The faster you ship code, the more chances there are for something untrusted to slip through. That’s where DevSecOps comes in, baking security right into the process instead of tacking it on at the end.

One of the best ways to build that trust is with code signing. When you sign container images, you’re basically stamping them with a seal that says, “This came from us, and it hasn’t been messed with.” It’s a simple check that goes a long way in making sure what you’re running in production is exactly what you meant to build.

Our platform, CodeSign Secure, plugs into your CI/CD pipeline so signing isn’t a separate task; it’s just part of the build. Every image that gets built and pushed can be signed automatically. And before it gets deployed, it can verify the signature to make sure nothing was tampered with along the way.

It’s about putting security on autopilot. You shouldn’t have to choose between moving fast and staying secure with our platform; you get both.

Signing Container Images with CodeSign Secure

Before proceeding with image signing, Docker & CoSign (our CodeSign Secure’s CLI tool) need to be installed on that machine.

Please follow the steps mentioned below for installing cosign

Installing CoSign

# binary

wget “https://github.com/sigstore/cosign/releases/download/v2.0.0/cosign-linux-amd64”

mv cosign-linux-amd64 /usr/local/bin/cosign

chmod +x /usr/local/bin/cosign

# rpm

wget “https://github.com/sigstore/cosign/releases/download/v2.0.0/cosign-2.0.0.x86_64.rpm”

sudo apt-get update

sudo apt-get install ca-certificates curl gnupg lsb-release

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg –dearmor -o /etc/apt/keyrings/docker.gpg echo “deb [arch=$(dpkg –print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

sudo apt-get install docker-ce-rootless-extras

Now you would need to log in to your Docker Hub account by running the below command

sudo docker login

Setting up Container Signing

Download the Container Signing Tools from the CodeSign Secure portal.
Go to folder SignImage
Open the “ec-signer.conf” file and update the codesigning URL, the path of your SSL Authentication certificate, and the password of the certificate.

NOTE: The SSL Authentication Certificate and password can be generated from the CodeSignSecure portal.
Open terminal
Execute
./ec-signer –project_name=<certificate name> –image_name=<target container> –docker_username=<your docker username>
You will be prompted to provide the Docker Hub password and the root privileges to the current user
You will be able to see a new signature image on your Docker Hub account.

Verifying Container Image

Verification of Container Images will allow you to deploy only signed Docker images and reject unsigned ones. Kubernetes needs to be deployed to verify the container image signing.

Installing Kubernetes

Please follow the following command to install Kubernetes.

curl -sfL https://get.k3s.io | sh –

Creating Kubernetes Services

Before we can verify an image in a Kubernetes environment, the following services need to be deployed in the Kubernetes cluster

Verify Image Service
Image Validation Webhook Service

To create the Verify Image Service, follow the steps below:

Go to the ../VerifyImage/image-verifier directory.
Create a Docker image with the name “verifyImage” using the Dockerfile present in the folder
For example:

sudo docker build -t aryan34/demo:verifyImage

where “aryan34” is the Docker username and “demo” is the Docker Hub repository name.
Now push this image to your Docker Hub account
For example:

sudo docker image push aryan34/demo:verifyImage

where “aryan34” is the Docker username and “demo” is the Docker Hub repository name.
Now open the validator-deploy.yaml file and update the following settings

cert_name
server_url
pfx_file_path
pfx_file_passwd
DOCKER_USERNAME
DOCKER_PASSWORD
image (NOTE: Keep the image name as “verifyImage”. Only change the docker username and repository name.)

Deploy the Image Verifier Service
sudo kubectl apply -f validator-deploy.yaml

To create the Image Validation Service, follow the steps below:

Go to the ../VerifyImage/validating-webhook directory.
Create a Docker image with the name “image-validation-webhook” using the Dockerfile present in the folder.
For example:

sudo docker build -t aryan34/demo:image-validation-webhook

Where “aryan34” is the Docker username and “demo” is the Docker Hub repository name.
Now push this image to your Docker Hub account
For example:

sudo docker image push aryan34/demo:image-validation-webhook

where “aryan34” is the Docker username and “demo” is the Docker Hub repository name.
Now deploy the webhook secrets and configuration yaml files.
sudo kubectl apply -f webhook-secret.yaml

sudo kubectl apply -f webhook-config.yaml
Now open the webhook-deploy.yaml file and update the following settings
1. image (NOTE: Keep the image name as “image-validation-webhook”. Only change the docker username and repository name.)
Deploy the Image Validation Webhook
sudo kubectl apply -f webhook-deploy.
If the services are successfully deployed, when we execute the following command –
sudo kubectl get pods -all-namespaces

We should get the following output –

Testing

If we try to deploy any container image that is not signed, the deployment will fail. We will only be able to deploy a signed image due to our verifier and validation Kubernetes services.

Deploying an Unsigned Image

We need to create a yaml file for the unsigned image

We have created a demo-deployment-unsigned.yaml file to deploy the unsigned aryan34/demo:notSigned image.

Here is a sample yaml file. Remember to change the Deployed service name (demo-deployment-unsigned), image name, and the port number.

apiVersion: apps/v1
kind: Deployment
metadata:
name: demo-deployment-unsigned
labels:
app: demo
spec:
replicas: 1  # Number of desired replicas
selector:
matchLabels:
app: demo
template:
metadata:
labels:
app: demo
spec:
containers:
- name: demo
image: aryan34/demo:notSigned  # unsigned demo image
ports:
- containerPort: 8997  # Port to expose

To deploy the unsigned image using Kubernetes, run the following command.

sudo kubectl apply -f demo-deployment-unsigned.yaml

Deploying a Signed Image

Here is a sample yaml file. Remember to change the Deployed service name (deployed-demo), image name, and the port number.

apiVersion: apps/v1 
kind: Deployment 
metadata: 
name: demo-deployment 
labels: 
app: demo 
spec: 
replicas: 1  # Number of desired replicas 
selector: 
matchLabels: 
app: demo 
template: 
metadata: 
labels: 
app: demo 
spec: 
containers: 
- name: demo 
image: aryan34/demo:new3  # signed demo image 
ports: 
- containerPort: 8999  # Port to expose

To deploy the signed image using Kubernetes, run the following command.

sudo kubectl apply -f demo-deployment.yaml

Now, if you check all the pods, you will see a demo-deployment service successfully running.

CodeSign Secure + SBOM: Ensuring Supply Chain Transparency

Knowing what’s inside your containers is just as important as knowing who built them. That’s where SBOMs (Software Bill of Materials) come in. They list out all the components in your container image, kind of like a nutrition label for your software.

With our CodeSign Secure, you can sign your SBOMs and attach them directly to your container images. That means anyone pulling your image can check both the image and the SBOM to confirm they’re legit and untouched.

Our platform supports popular SBOM formats like SPDX, so you’re covered no matter what tooling you’re already using. And the best part? You can enforce these checks. If an image shows up without a signed SBOM or if the SBOM doesn’t match what’s expected, you can block the deployment right there.

No SBOM? No deployment. Simple.

This gives you visibility into what’s running, and it helps catch issues before they turn into security problems later on.

CodeSign Secure and Post-Quantum Cryptography

Quantum computing isn’t here yet, but when it shows up, a lot of current encryption methods could be in trouble. Algorithms like RSA and ECC, which we rely on for signing today, won’t stand a chance against a powerful enough quantum machine.

That’s why our platform, CodeSign Secure, is ready now with support for LMS (Leighton-Micali Signature), one of the post-quantum algorithms recommended by NIST. LMS is designed to stay strong even if quantum computers become a real threat.

You can already start testing our platform with LMS to see how post-quantum signing fits into your pipeline. It works with HSMs that support LMS and integrates just like any other algorithm CodeSign Secure handles. No special tricks needed.

Looking ahead, we will keep adding support for more post-quantum algorithms as standards become finalized, including those from the NIST PQC competition. So, when the shift to quantum-safe signing becomes necessary, you won’t need to scramble; we’ll have you covered.

Enterprise-Grade Features

When you’re running code signing at scale, you need more than just a signature. You need control, visibility, and the flexibility to fit into how your team works.

Role-Based Access Control & Auditing: Not everyone should be able to sign every image. With our CodeSign Secure’s RBAC, you can set up fine-grained permissions so only your release engineers can approve production builds, while developers get access to lower-risk environments. Every signing action is logged automatically, giving you a full audit trail of who signed what, when, and with which key.

Central Dashboard for Signing Visibility: Gone are the days of hunting down logs across multiple CI jobs. Our platform’s dashboard brings all your signing events into one place, showing you at a glance which images have valid signatures, which keys they used, and any failed verifications. If something looks off, you’ll spot it right away and can click through for details.

API-First Architecture for Custom Integrations: Want to hook our platform into your own tools or automate a custom workflow? All CodeSign Secure features are exposed via a well-documented REST API so you can script virtually anything to trigger a sign-and-push step in your bespoke CI tool, build internal reporting, or integrate with the security ticketing system you already use.

With these enterprise features, CodeSign Secure not only signs your images but also helps you manage and monitor every step of the process.

Conclusion

Supply chain threats aren’t going away, and ignoring them isn’t an option. But locking things down doesn’t have to slow you down. With our CodeSign Secure, you get a tool that fits right into your existing pipeline, adds strong security where it counts, and keeps you in control from build to deploy.

From signing container images and SBOMs to verifying them with HSM-backed keys and prepping for a quantum-safe future, our platform helps you check all the boxes, without adding friction for your team.

If you’re ready to take container security seriously without making your workflows more complicated, give our CodeSign Secure a try.

What should you look for in the PQC Advisory or Support Service?

It is no longer breaking news that the National Institute of Standards and Technology (NIST) has officially selected five post-quantum cryptographic algorithms, a long-anticipated move that marks a crucial step in the cryptographic shift toward quantum resilience. Additionally, NIST has also made it clear that by 2030, widely used algorithms such as RSA, Elliptic Curve Diffie-Hellman (ECDH), MQV, Finite Field DH, ECDSA, and EdDSA (at 112-bit security strength) will be deprecated.

Let us quickly recap the five algorithms selected by NIST:

Current Specification Name	Initial Specification Name	FIPS Name	Parameter Sets	Type
ML-KEM-1024	CRYSTALS – Kyber	FIPS 203	Kyber512 Kyber768 Kyber1024	Lattice-Based Cryptography
ML-DSA-87	CRYSTALS – Dilithium	FIPS 204	Dilithium2 Dilithium3 Dilithium5	Lattice-Based Cryptography
SLH-DSA	SPHINCS+	FIPS 205	SPHINCS+ – 128s SPHINCS+ – 192s SPHINCS+ – 256s	Hash-Based Cryptography
FN-DSA	FALCON	FIPS 206	Falcon – 512 Falcon – 1024	Lattice-Based Cryptography
HQC	HQC (Hamming Quasi–Cyclic)	Pending Standardization	HQC – 128 HQC – 192 HQC – 256	Code-Based Cryptography

So, what does this mean for us? In simple terms, by adopting these algorithms, we are not just preparing for the future, we are building a security net before quantum computers become a real-world threat.

While quantum computers are still in the developmental phase, experts agree that it is only a matter of time before they become powerful enough to break today’s encryption. What’s even more concerning is that attackers are not sitting idle. They are already capturing encrypted data today and storing it until quantum technology is advanced enough to decrypt it. This approach, known as “harvest now, decrypt later,” poses a growing threat to governments, enterprises, and anyone handling sensitive information.

The impact, however, extends far beyond that. Quantum attacks could also break the PKI systems used to issue digital certificates, shaking the foundation of trust in secure communication, email security, and online transactions. Without crypto agility, replacing vulnerable algorithms will require major system overhauls, causing operational downtime, compatibility issues, and high costs. There is also the risk of forged digital signatures, allowing attackers to impersonate trusted identities. And perhaps most critically, traditional encryption algorithms like RSA and ECC will no longer be able to protect data, making confidential information vulnerable to decryption by quantum computers.

So, what is the risk of waiting? Delaying the transition to quantum-safe cryptography could leave sensitive data such as PHI, PII, and PCI exposed in the years to come. That is why governments, financial institutions, and tech giants have already begun working with PQC advisory partners to assess risks, plan migrations, and integrate quantum-safe strategies into their critical infrastructure and supply chains.

The time to act is now. But making the shift to post-quantum cryptography (PQC) is not just about urgency, it is about doing it right. Organizations need guidance from experts who understand the complexities of cryptographic environments. Specialized PQC advisory services can help assess existing systems, identify potential risks, and design a smooth, secure roadmap for adopting quantum-safe algorithms.

Why Do You Need a PQC Advisory or Support Service?

Making the shift to PQC requires understanding what is at risk, auditing existing cryptographic systems, identifying where vulnerable algorithms are used, and planning how to migrate the legacy infrastructure without causing service disruptions. That involves updating protocols, keeping systems compatible, and making sure everything continues to run smoothly during the shift. Therefore, organizations need dedicated PQC advisory services to carry out comprehensive assessments, develop customized strategies, and build a phased roadmap that supports a secure and efficient migration to quantum-safe cryptography.

Here is why having a PQC advisory or support team by your side makes all the difference:

Comprehensive Risk Assessment is Needed
Before you can start planning a migration, you need to understand where your systems are most vulnerable to quantum threats. This begins with a thorough risk assessment to identify vulnerabilities, outdated algorithms, weak cryptographic implementations, and potential gaps that quantum computers could exploit. The insights from this analysis help you focus on the most critical areas first and allocate your resources efficiently for a smooth and secure transition.
One-Size-Fits-All Strategies Don’t Work
Every organization has its own infrastructure, risk profile, and business priorities. Relying on a generic migration plan can lead to inefficiencies or leave important assets unprotected. That is why it is important to assess your specific environment and build a customized PQC roadmap. A tailored approach ensures you strike the right balance between your operational needs and long-term security goals.
PQC Migration Is Complex
Migrating to PQC is not just another technical upgrade, it is a structural change across your entire cryptographic infrastructure. Everything from key exchange mechanisms and digital signatures to internal APIs and protocol layers needs to be reviewed and updated for quantum resilience. On top of that, securely migrating existing cryptographic keys and assets adds another layer of complexity. To make this process more manageable, a systematic approach is needed, one that helps identify risks, prioritize changes, and enable cryptographic agility without disrupting existing operations.
Specialized Expertise Is Essential
Specialized expertise is essential when it comes to post-quantum cryptography. With new algorithms, evolving standards, and complex implementation challenges, navigating this shift requires deep, up-to-date knowledge. Rather than expecting internal teams to master this rapidly changing space, it makes sense to rely on PQC experts who bring the latest knowledge of PQC algorithms, NIST recommendations, performance trade-offs, industry best practices, and deployment strategies.
Ongoing Support and Compliance Alignment Matters
Quantum readiness is the ability of an organization to prepare for and adapt to the security challenges posed by quantum computing. It is not a one-time project, but a continuous journey that requires long-term attention and strategic oversight. Without expert guidance, organizations risk falling out of compliance or overlooking critical updates. Long-term advisory support ensures your cryptographic systems evolve with the latest standards, your teams stay informed through training, and your organization stays aligned with a proactive, future-proof, quantum-safe approach.

These are just a few reasons why PQC advisory and support service really matters. The right partner can help you stay ahead of quantum threats without disrupting your current operations.

But with so many options out there, the bigger question is, how do you choose the right services for quantum readiness and impact assessments?

Key Qualities of a Trusted PQC Advisory Partner

Now that you know why expert help matters, let us explore what to look for when choosing your PQC advisory partner. Here are the key factors to keep in mind when evaluating a Post-Quantum Cryptography (PQC) service provider:

Proven Cryptographic Expertise
Choosing the right services for quantum readiness means working with experts who bring deep knowledge of both classical and post-quantum cryptography. It is essential that they closely follow NIST’s standardization process and understand how each candidate algorithm performs under real-world conditions. Just as importantly, they should be able to evaluate the strengths and trade-offs of each post-quantum approach and align those insights with your specific use cases, system architecture, and performance requirements.
Experience with Legacy-to-PQC Migrations
Successful quantum readiness requires experience, particularly in migrating legacy systems. Legacy environments often use outdated protocols and hardcoded cryptographic libraries, making them difficult to upgrade without disrupting operations. These systems were never designed to mitigate quantum threats or even to support crypto agility, which makes upgrades even more difficult. That is why it is critical to work with advisors who can assess your existing cryptographic environment and seamlessly integrate quantum-safe algorithms, all while ensuring minimal disruption and maintaining operational continuity.
Support for Algorithm Suitability and Cryptographic Agility
Not all quantum-resistant algorithms are designed to perform equally across different cryptographic environments. That is why it is important to evaluate them based on your specific needs, whether that’s performance, device constraints, or bandwidth limitations.

For instance, ML-DSA is used for digital signatures. It is all about making sure that the data remains unchanged and authentic. On the other hand, ML-KEM is used for key exchange, much like RSA or Diffie-Hellman, and is perfect for protecting data confidentiality as it moves across networks.

Also, make sure your partner values cryptographic agility, which is the ability to adapt to new algorithms as standards mature or new threats arise. Any advisory team you engage should prioritize this flexibility, ensuring your systems remain secure and future-ready as quantum technology continues to advance.
Comprehensive Risk Assessment and Strategy Development
Effective quantum readiness begins with visibility. You need a partner who can audit your existing cryptographic assets, identifying what is vulnerable, what is urgent, and what can be addressed over time. This begins with creating a clear cryptographic inventory that shows where and how encryption is used across your systems. From there, the advisory team should perform a quantum risk impact analysis to understand which systems are most exposed. A strong partner will go beyond surface-level scans and help you build a crypto-agility profile and a quantum risk heatmap, giving you a clear picture of your overall risk and preparedness.

Remember, PQC migration is not just about replacing algorithms. It is about understanding your organization’s unique cryptographic environment and executing a focused, strategic plan. The right team will help you carry out a comprehensive risk assessment, define a prioritized action plan, and develop a phased migration and mitigation strategy customized to your needs. They will also support pilot testing, ensure smooth implementation, and keep your systems updated as new standards and threats emerge.
Integration and Migration Support
Implementing post-quantum cryptography is not a one-size-fits-all process, especially when your infrastructure spans cloud, on-premises, and hybrid environments. You need a team that can navigate this complexity step by step, starting with pilot tests in controlled environments to identify and resolve issues early. After that, they should be able to smoothly integrate PQC into a production environment. This includes managing cryptographic keys, protocols, and infrastructure across all platforms while making sure the transition to quantum-safe cryptography is smooth, secure, and resilient.
Ensure Backward Compatibility
Transitioning to post-quantum cryptography is not about ripping out existing systems, it is about enabling coexistence. To ensure backward compatibility with legacy infrastructure, it is essential to adopt hybrid deployments that combine classical algorithms (like RSA or ECC) with post-quantum algorithms (such as Kyber). An experienced partner should be able to seamlessly integrate these hybrid cryptographic models into existing legacy systems, APIs, TLS stacks, and mobile environments while balancing performance, interoperability, and security.
Ongoing Monitoring and Support
Quantum threats are not static, and neither are the standards meant to fight them. You need continual updates, algorithm replacements, and regular security monitoring to stay protected. So, look for a partner that offers long-term support, timely threat intelligence, and the flexibility to adapt your cryptographic posture as new standards and risks evolve.
Cost-Effectiveness and Value
Security is non-negotiable but so is staying within budget. That is why it is important to work with a partner who delivers cost-efficient solutions without compromising cryptographic strength. The right team will help you maximize the value of your investment, delivering quantum-resistant protection without overengineering or overspending.

Choosing the right PQC partner is not just about checking boxes. It is about building a trusted relationship with a team that understands the bigger picture and offers hands-on support. PQC is a journey, and the sooner you start with the right support, the smoother and more cost-effective your path to quantum safety will be.

Key Role of Certificate Lifecycle Management in SSL Management

SSL/TLS certificates play a vital role in securing online communication, protecting sensitive information, and establishing user trust. However, as organizations grow and adopt hybrid, multi-cloud, or CI/CD-driven environments, managing certificates manually becomes increasingly complex and error-prone. The fast pace of DevOps and the distributed nature of modern infrastructure make it especially challenging to scale SSL management effectively without automation.

That is where Certificate Lifecycle Management (CLM) plays a significant role.

In this blog, we are going to explore how effective CLM simplifies SSL certificate management, mitigates human error, supports compliance, and enhances visibility across your digital infrastructure.

Managing SSL the Right Way: The Power of Certificate Lifecycle Management.

Certificate Lifecycle Management (CLM) is the systematic process of issuing, discovering, tracking, renewing, and revoking digital certificates in a systematic and centralized manner. Below is a more detailed breakdown of its key benefits and why it plays a vital role in managing SSL the right way:

Automation
- Handles certificate issuance, renewal, and replacement automatically, with no manual intervention needed.
- Leverages standard protocols like ACME and SCEP to streamline integration with certificate authorities, devices, and systems.
- Minimizes the risk of service outages caused by expired certificates.
- Eliminates repetitive, time-consuming manual tasks, reducing the operational burden on IT and security teams.
Visibility
- Provides a centralized inventory of all digital certificates across the organization.
- Offers real-time monitoring and alerts in case of expiry or misconfigured certificates.
- Helps to identify certificates that are unused or non-compliant, which helps in reducing security risks.
Security
- Enforces strict access controls and policies for certificate requests and usage.
- Prevents unauthorized certificate issuance or misuse of certificates.
- It also manages to reduce human errors, a major cause of mismanaged SSL environments.
Compliance
- Supports regulatory requirements and aligns with the internal security policies.
- Maintains comprehensive audit logs for all certificate-related activities.
- Enables faster, more precise reporting during security audits or compliance reviews.

From Issuance to Expiry: Mastering SSL with Lifecycle Management

For effectively managing SSL/TLS certificates, just deploying them is not enough; it also demands end-to-end management of their entire lifecycle. From initial issuance to timely renewal and eventual expiry or revocation, every stage plays a crucial role in ensuring that security and trust are uninterrupted. This becomes especially important in today’s hybrid environments, where certificates are distributed across cloud platforms, edge devices, and IoT ecosystems.

Certificate Lifecycle Management (CLM) provides the automation, visibility, and control needed to handle each phase with confidence and efficiency, regardless of where the certificate resides.

Let’s take a deeper look at how CLM supports every step of the SSL certificate lifecycle:

Issuance
- Structure certificate request workflows that reduce manual intervention and delays.
- Ensures that all certificate requests meet internal security and compliance standards.
- Supports CSR (Certificate Signing Request) validation flows, including manual approval processes and automated policy checks, to maintain control and security.
- Integrates with trusted Certificate Authorities (CAs), enabling quick issuance from preferred internal or public CAs.
- Tracks request history and approvals to ensure the certificate process is traceable and accountable.
Discovery
- Scans your networks and systems to find all deployed certificates, which also include those that were manually installed, forgotten, or undocumented.
- Supports both agent-based and agentless discovery methods—offering flexibility depending on your environment’s needs and constraints.
- Uncovers unsafe or unauthorized certificates that could lead to hidden vulnerabilities or security risks.
- Giving teams a complete, up-to-date view of all SSL assets across environments through a centralized certificate inventory.
- Categorizes certificates by owner, department, and use case, simplifying management and ownership accountability.
Tracking & Monitoring
- Continuously monitors certificate status, including expiration dates, configuration details, key strength, and issuer information—tasks that are nearly impossible to manage manually at scale.
- Sends proactive alerts and notifications well in advance of expirations, policy violations, or configuration issues, helping teams avoid last-minute surprises and downtime.
- Promotes cryptographic hygiene by detecting deprecated key lengths, outdated hashing algorithms, or misconfigured parameters, ensuring that all certificates align with evolving security standards.
- Provides role-based dashboards and reports, making it easier for teams to track performance, risk exposure, and certificate health in real time.
- Detects unusual activities—such as unexpected changes or unknown issuers—and flags them for immediate investigation to prevent potential misuse or compromise.
Renewal
- Makes sure that all the certificates are renewed to ensure no certificate is forgotten or allowed to expire; this helps in eliminating one of the most common causes of service outages.
- Supports renewing multiple certificates together, which helps in saving time and reducing friction for teams managing hundreds or thousands of certificates.
- Enables seamless replacement of expiring certificates without disrupting active services or user trust.
- Integrates with DevOps pipelines and CI/CD tools to renew certificates automatically in the ever-changing and fast-moving environments.
Revocation & Expiry
- Provides quick and secure options to revoke certificates that are no longer needed or trusted.
- Prevents expired or revoked certificates from being used, which helps in maintaining continuous service availability and trust with users.
- Maintains detailed audit logs and compliance records, which help organizations to prove proper certificate handling during security assessments or audits.
- Supports certificate replacement workflows, which ensure the replacement of revoked certificates with new valid ones.

Avoiding Outages and Breaches Through Certificate Lifecycle Control

Digital identities that are unmanaged or poorly tracked can lead to unexpected service outages and serious security breaches. In fact, even a single expired or misconfigured SSL/TLS credential can bring down critical systems, disrupt user access, and erode trust. That’s why Certificate Lifecycle Management (CLM) is more than just a best practice—it’s a necessity for any modern enterprise.

Here’s how effective CLM helps in avoiding costly outages and preventing breaches:

Proactive Expiry Alerts
- The team is notified in advance about the upcoming expirations through automated notifications and reminders.
- Reduces the risk of downtime caused by overlooked certificate renewals.
Eliminating Blind Spots
- CLM tools perform continuous discovery across all environments, identifying certificates which are forgotten, rogue, or shadow.
- Helps eliminate vulnerabilities caused by unmanaged or expired certificates.
Automated Renewal & Replacement
- Prevents lapses in encryption by auto-renewing certificates before expiry.
- Seamless transitions ensure that the users and systems stay secure and connected without interruption.
Reduced Human Error

By automating repetitive and sensitive certificate tasks, CLM reduces the likelihood of mistakes that often lead to misconfigurations or missed updates, as there is no manual intervention.
Improved Response to Compromise

If a certificate is compromised or no longer trusted, CLM immediately removes and replaces it to reduce the threat.
Audit-Ready Compliance
- Maintains logs and records of all certificate activities to show strong security management and compliance with industry standards.
- Real-world incidents like the Equifax breach, where an expired certificate prevented malware detection for over 19 months, or the Microsoft Teams outage in 2020, caused by a single expired certificate, highlight the critical need for continuous compliance and vigilant lifecycle control.

Automating SSL: The Role of Lifecycle Management in Modern PKI

Evolving digital infrastructures make managing SSL/TLS certificates manually harder, error-prone, inefficient, and risky. In modern Public Key Infrastructure (PKI) environments, where certificates secure everything from websites and applications to APIs and IoT devices, automation is no longer optional. This is where Certificate Lifecycle Management (CLM) becomes a crucial component.

Here’s how CLM supports automation in modern PKI:

- Adapts seamlessly to ephemeral services such as containers, serverless functions, and short-lived workloads, ensuring that even transient environments remain secure and compliant without manual oversight.

Keeping SSL Certificates Secure and Compliant with CLM

SSL/TLS certificates are important for keeping the communication secure, but manually managing them can be risky, from expirations and misconfigurations to compliance failures. Certificate Lifecycle Management (CLM) solves this problem by automating processes and keeping control over the certificate lifecycle.

How CLM ensures security and compliance:

Strong Security: Enforces crypto policies, blocks unauthorized access, and integrates with HSMs for securing the key storage.
Compliance Enforcement : Meets compliance standards (e.g., NIST, PCI-DSS), maintains audit trails, and ensures that policies are followed. Supports integration with compliance and vulnerability scanning tools such as Qualys, Nessus, or similar platforms to help identify outdated certificates and encryption weaknesses.

How to Start Your Enterprise Post Quantum Cryptography Migration Plan

The best time to think about post-quantum cryptography (PQC) Migration was yesterday. The next best time is today. Every day that traditional cryptography remains in use is a window of opportunity for attackers to harvest and store encrypted data, with the intent to decrypt it once quantum computing matures.

Recognizing this, Microsoft has taken a significant step by introducing early support for NIST-selected PQC algorithms, ML-KEM (for key encapsulation) and ML-DSA (for digital signatures), support to Windows systems through updates to the Cryptography API: Next Generation (CNG) and cryptographic messaging functions. These updates are currently available for Windows Insiders, allowing early access for testing and development.

PQC Migration sounds exhaustive, and it is indeed a big change. But it doesn’t have to happen overnight. It’s a long-term, strategic effort that requires a deep understanding of where cryptography is used within your organization and how to replace it without breaking critical systems. Let’s break down the phased and strategic approach to PQC migration.

Planning your PQC Migration

Quantum risk isn’t a problem of the future. It’s a planning failure of the present. The planning process begins with gaining visibility, organizing your crypto assets, assessing risks, aligning vendors, testing thoroughly, and designing for long-term agility, your organization will be ready for the quantum future.

Below is a practical roadmap to begin your organization’s PQC journey:

Establish a Quantum Readiness Program

Before implementing technical changes, establish a Governance framework by setting up a dedicated PQC migration team that includes stakeholders from various use cases within your organization. This team should own the roadmap, assign responsibilities, monitor progress, and align PQC goals with your organization’s long-term strategy.

Migration to PQC involves multiple internal teams. Before implementation begins, everyone must be on the same page. It’s essential to ensure that all stakeholders understand what PQC is, why it matters, and how it will impact their workflows. This is a small but important step as your team needs to understand both the “why” and the “how”.

Perform a Cryptographic Discovery

This step is about knowing exactly where and how cryptography is used across your environment. Many organizations are unaware of all the certificates they use, especially hidden or “shadow” certificates. Using automated discovery tools, you scan your systems, networks, and cloud environments to locate TLS/SSL certificates, code signing keys, email certificates, and more. This step is crucial because you can’t protect or upgrade what you don’t know exists. This includes

TLS/SSL certificates on websites and applications,

Public/private key pairs

VPNs, databases, internal APIs

Code signing, firmware, and secure email

Vendor-supplied applications and IoT devices

Discovery should cover every layer, on-premises servers, cloud platforms (AWS, Azure, GCP), network appliances (like load balancers or firewalls), and IoT/embedded systems.

Automated discovery tools help uncover both managed and unmanaged certificates, offering enterprise-grade capabilities for, agentless and agent-based discovery, real-time certificate tracking, automated expiration alerts and key usage analytics, API integrations with internal PKI and public CAs. These platforms can scan both on-prem and cloud environments using credentialed access, SSH, WMI, SNMP, and integration with orchestrators (like Ansible, Kubernetes, Terraform) to discover certificates embedded in CI/CD pipelines

Build a Cryptographic Inventory

Once discovery is complete, compile all certificate telemetry into a centralized inventory system, preferably integrated with your CMDB and asset management platforms. An up-to-date cryptographic inventory provides a single source of truth for planning your PQC transition. Provide each certificate entry with:

Cryptographic attributes: Algorithm (RSA-2048, ECDSA-P256), key length, hash algorithm

Cryptographic Libraries (e.g., OpenSSL, BouncyCastle), Cryptographic protocols (TLS 1.3/1.2, SSH, IPsec)

Internal systems (servers, desktops, databases), Network infrastructure (firewalls, VPNs, load balancers)

Key and Certificate Lifecycle metadata: Issuance and expiry dates, renewal history

Infrastructure bindings: Associated domain names, IP addresses, system FQDN, port usage

Ownership and scope: Application owner, business unit, asset criticality

Source CA: Internal (Microsoft ADCS, EJBCA) or third-party (DigiCert)

Dependencies in CI/CD pipelines or firmware updates

The next step is to convert that raw data into a structured and actionable cryptographic inventory. This inventory forms the backbone of your PQC migration plan and should classify each asset based on the following criteria:

What cryptographic algorithms are used?

Where are the cryptographic algorithms used (by system, app, protocol)?

Which business functions do they protect?

What is the validity period of the certificates issued by public CA and private CA?

What is the lifespan of protected sensitive data?

For example, customer PII data often has a long shelf life, making them immediate candidates for PQC.

Analyze Risk and Prioritize

Now that you have a cryptographic inventory in place, it is time to perform the risk analysis for each asset or service. Evaluate each system for how vulnerable it is to quantum attacks, the sensitivity of the data it protects, and how long that data must remain confidential. Systems handling personal, financial, or national security sensitive data should be prioritized.

Risk-based prioritization ensures that you migrate critical systems first, not just the ones that are easiest to fix. Use risk assessment frameworks to assign scores (e.g., high, medium, low). Map cryptographic risk to business risk, such as service disruptions, operational downtime, etc. This step ensures your migration plan is focused on what matters most, minimizing potential damage from future quantum threats.

Use quantitative frameworks (e.g., NIST 800-57, ISO/IEC 27005) or vendor-provided scoring models to tag each asset with a risk score. Create heatmaps to visualize PQC impact zones, especially where high-sensitivity data intersects with quantum-vulnerable algorithms.

Classify data (e.g., PII, PCI) and determine retention needs (e.g., 7–10 years for healthcare records). Asses the exposure of algorithms quantum threats, such as RSA, DSA, DH, and ECC curves (like P-256) are vulnerable to Shor’s algorithm.

At this point, it is important to understand which systems, if decrypted tomorrow, would cause the most damage?

Use the analysis to prioritize a phased migration plan, starting with high-impact or low-complexity assets.

Evaluate the Tools and Platform Readiness

Now begin evaluating what tools and algorithms you will need to support migration. This is where Microsoft’s update becomes important.

“Don’t wait for final standards. Start testing hybrid now.” – NIST PQC Roundtable

With ML-KEM and ML-DSA now supported in Windows via CNG, enterprises can begin building and testing post-quantum-ready applications without replatforming.

Test hybrid algorithms in your Windows environment

Simulate key exchange with ML-KEM and RSA together

Use APIs to build pilot apps with forward secrecy

This gives your teams a safe, supported sandbox to develop crypto agility, and it aligns with NIST’s guidance that early experimentation is key. Check for tools that support hybrid cryptography, combining classical + PQC algorithms in one certificate. This is important for gradual migration. Test how the new algorithms affect performance, bandwidth, and application compatibility, since they typically use larger keys and signatures.

Build a Migration Roadmap

This is where planning becomes action. After the groundwork is laid, build a step-by-step migration roadmap. This plan should include phases, starting with low-risk systems for testing, then moving to high-priority and public-facing systems.

Create a timeline for staged PQC implementation and break down the migration into the plan:

Define short-term and long-term goals aligned with risk and criticality.

Define roles, timelines, tools, budget, and success metrics.

Define phases for migration, such as Phase 1 (2025–2026)- Pilot deployments in non-production or sandboxed environments. Phase 2 (2026–2029): Migrate high-risk internet-facing services and APIs. Phase 3 (2029–2035): Plan full transition for high-priority systems and organization-wide.

Decommission legacy crypto and shift to pure PQC where feasible.

It should assign owners, set timelines, and define fallback options in case things go wrong. A roadmap ensures the transition is organized, trackable, and accountable across the enterprise. Sequence your rollout with risk-aligned prioritization, fallback plans, and vendor integrations.

Pilot Deployment and Gradual Rollout

Before deploying at scale, conduct pilot tests using hybrid certificates and PQC-enabled protocols like TLS with Kyber. PQC migration will expose unknown breakpoints. Controlled pilots allow you to identify and fix issues without impacting production.

Evaluate how your applications handle larger key sizes and new certificate formats. Roll out gradually, start internally, then expand to external services. This phased approach helps identify issues early and prevents major disruptions in live environments. Launch PQC pilots by:

Deploying hybrid TLS certificates (RSA + Kyber) via ACME-compatible internal CA

Updating TLS endpoints to support PQC negotiation (Apache, NGINX, Envoy, IIS)

Testing OCSP, CRL, and SCT response flows under hybrid signing

Benchmarking PKI workloads: CSR issuance, key generation, signing, revocation.

Performance impact on servers and clients

Once pilots are successful, they roll out to production gradually. Start with internal services, then customer-facing apps, while monitoring compatibility with legacy systems and clients.

Monitor and Manage your Cryptographic Posture

Once deployed, PQC isn’t “set and forget.” Continuous monitoring and adaptation are essential. Once migration begins, you need to monitor your cryptographic systems continuously. Use dashboards and alerts to track certificate expirations, detect use of outdated algorithms, and flag failed crypto operations.

Set alerts for:

Expiring PQC or hybrid certs

New RSA/ECC certs appearing post-migration

Validation errors in legacy clients

TLS negotiation failures on hybrid endpoints

Post-deployment, Link this data to your SIEM dashboards (e.g., Splunk) with crypto logs and CLM solutions that auto-discover certs and detect drift.

Build Cryptographic Agility for the Future

Post-quantum migration is not the end, it’s a step toward agility. Crypto agility ensures you’re never locked into a broken algorithm again. Design your systems to easily swap algorithms using modular libraries or plug-in architecture.

Continuously monitor PQC performance, compatibility, and emerging algorithmic updates. Crypto-agile systems should:

Swap algorithms easily as standards evolve

one-click certificate operations like renewal, migration, ownership transfer, revocation

One-click Public CA migration

Updating organization’s internal policies and standards in response to NIST and industry guidance

Use Certificate Lifecycle Management (CLM) platforms that support multiple cryptographic standards and automate renewal and rotation.

Key Use Cases you can Start Testing Today

Microsoft is enabling PQC experimentation in critical cryptographic functions, such as:

ML-KEM for key exchange: Ideal for testing PQ-safe alternatives to RSA and ECDH. Use this in key encapsulation scenarios and hybrid exchanges (ML-KEM + RSA or ECDH) for added resilience.

ML-DSA for digital signatures: Use this to explore post-quantum identity and integrity validation. ML-DSA can be used alongside existing algorithms like ECDSA or RSA in composite mode, offering transitional compatibility.

Certificate store integration: With PQC now added to wincrypt (the certificate API layer), organizations can:

Import/export ML-DSA-based certificates.

Validate PQC certificate chains.

Experiment with real PQ trust chain workflows using the familiar Windows certificate store.

These changes provide hands-on testing opportunities within enterprise-grade systems, allowing you to evaluate PQC readiness without needing to overhaul your infrastructure right away.

Microsoft’s support allows you to build crypto agility, evaluate performance impacts, and understand deployment nuances before PQC becomes mandatory.

Executing migration plan on your environment

Migrating to Post-Quantum Cryptography (PQC) varies depending on whether your environment is on-premises, cloud-based, or hybrid. Each has different architectural complexities, control levels, and dependencies, which impacts how you discover, manage, and replace quantum-vulnerable cryptography. However, for all environment use hybrid cryptography (PQC + classical) wherever possible to ensure backward compatibility.

Let’s understand an overview of how migration for PQC varies for different environments:

On-Prem environment

Use agent-based or network scanning tools to identify certificates, algorithms, and keys across endpoints, servers, applications, and devices.

Centralize and categorize your cryptographic assets (PKI, SSL/TLS certs, signing keys)

Upgrade libraries like Microsoft CNG, OpenSSL to support PQC algorithms.

Ensure hardware modules and internal certificate authorities support hybrid or PQ-safe algorithms.

Cloud Environment

Use cloud-native tools and APIs to list keys, certs, and services using RSA, ECC, etc.

Map services and data stores that rely on vulnerable crypto (e.g., encrypted S3 buckets, cloud DBs, IAM tokens).

Engage cloud providers to get their PQC timelines, for supporting ML-KEM, ML-DSA, etc.

Begin testing PQC with supported APIs (e.g., Azure’s PQC support in Windows Insiders, AWS KMS roadmap).

Hybrid Environment (On-Prem + Cloud)

Use platform-agnostic tools that can scan both environments.

Maintain a centralized view of all crypto assets, servers, applications, devices.

Prioritize systems with long-term confidentiality needs.

Conclusion

Migrating to Post-Quantum Cryptography is not just a security upgrade, it’s a foundational transformation in how organizations protect sensitive data.

The transition to PQC is a complex, long-term effort that spans cryptographic discovery, vendor collaboration, testing hybrid approaches, updating PKI, and integrating new cryptographic standards across infrastructure. But it doesn’t need to happen all at once. A phased, well-planned migration, starting today, will help organizations build crypto-agility, minimize disruptions, and maintain digital trust throughout the transition.

This is not just a forward-looking upgrade. It is a present-day mitigation against future decryption. Organizations must take a proactive stance, assess their cryptographic exposure now, and start integrating PQC transition plans, before it’s too late.

Simplifying mTLS in Microservices with CertSecure Manager

Introduction

Microservices have become the go-to way to build modern applications. Instead of one big application doing everything, you’ve got dozens (or even hundreds) of smaller services talking to each other over the network. This setup is great for scaling and flexibility, but it also opens up a lot of room for trouble, especially when it comes to how those services communicate.

Most people are familiar with TLS, which is what puts the lock icon in your browser. It encrypts traffic and keeps outsiders from snooping. But in microservices, traditional TLS isn’t enough. TLS usually authenticates just the server, not the client. That’s fine for browsing websites, but in a microservices environment, each service acts as both a client and a server, and they all need to verify who they’re talking to. That’s where mutual TLS (mTLS) comes in.

With mTLS, both ends of the connection present certificates to prove their identity. Think of it like a secret handshake; each service has to show its credentials before the conversation can begin. This mutual verification helps ensure that no unauthorized or rogue service can sneak into the system pretending to be something it’s not.

This is especially important for what’s called east-west traffic, the communication happening between services inside your environment (as opposed to north-south traffic between users and your app). Without encryption and identity checks, it’s all too easy for attackers to intercept traffic, impersonate services, or tamper with data-in-transit.

By adding mTLS into the mix, you’re not just encrypting the data; you’re also making sure that only trusted services are allowed to talk to each other. That means more secure communication, fewer security holes, and a much better foundation for zero trust across your microservices setup.

Understanding mTLS in Service Mesh Architecture

When you’re dealing with microservices that need to talk to each other, wiring up secure communication between every single one manually gets messy fast. That’s where service meshes like Istio, Linkerd, or Consul step in. They handle things like traffic routing, retries, and most importantly, security between services without forcing developers to hardcode logic into their apps.

So, how does mTLS actually fit into a service mesh? It all starts with something called a sidecar proxy. Most service meshes inject a small proxy like Envoy next to each service. Instead of services talking directly to one another, all traffic goes through these proxies. That gives the mesh control over the traffic, including how it’s encrypted and authenticated.

Here’s where mTLS kicks in. Each sidecar proxy gets its own certificate, and when two services need to talk, their sidecars handle the secure connection. The proxies swap certificates, check each other’s identity, and set up an encrypted channel before any data is exchanged. The services themselves don’t need to worry about any of this; the mesh takes care of it.

Sounds great, right? But it’s not all smooth sailing. mTLS certificates have short lifespans, especially in high-security environments. That means they need to be issued, renewed, and sometimes revoked regularly. If a certificate expires or is compromised, it can break communication or expose sensitive data. Doing all this manually or even semi-manually just doesn’t scale. And when something breaks, figuring out which cert caused the issue can be a nightmare.

That’s why automated certificate management becomes such a big deal in service mesh setups. Without it, mTLS can become more of a hassle than a help.

Why Manual mTLS Management Doesn’t Scale

In theory, using mTLS across your microservices sounds like a solid plan: encrypt everything, authenticate everything. But in practice, managing all those certificates by hand is a real headache, especially once things start to grow.

In a setup like Kubernetes, services are constantly spinning up, shutting down, scaling out, or getting redeployed. That means the certificates that those services rely on also need to be short-lived and refreshed frequently. It’s not like you can hand out a cert and forget about it for a year. We’re talking lifespans measured in days or even hours.

Now imagine trying to manually issue, distribute, and rotate certificates for every one of those services. One missed renewal, and suddenly, your services stopped talking to each other. That turns into outages, angry alerts, and a lot of time wasted chasing down expired certs.

It also puts extra pressure on developers and SREs who’d rather focus on building and maintaining reliable systems, not babysitting certificate lifecycles. Managing mTLS manually at scale is like trying to keep a hundred spinning plates from falling. It’s doable, sure, but eventually, something’s going to break.

And when it does, it’s not just an inconvenience. It’s a security risk. A compromised service with an outdated or unmanaged certificate might still be trusted by others if revocation isn’t handled properly. That opens the door to lateral movement, spoofing, and other types of attacks you thought mTLS was supposed to protect against.

The truth is, as your environment grows, manual certificate management just can’t keep up. It slows you down, makes things brittle, and turns mTLS from a security feature into a source of pain.

How CertSecure Manager Will Help You

This is where our CertSecure Manager comes in.

CertSecure Manager is built to take the pain out of managing mTLS certificates in modern, fast-moving environments. Instead of relying on manual steps, patchy scripts, or last-minute Slack alerts about expiring certs, our platform handles everything behind the scenes, issuing, renewing, rotating, and revoking certificates automatically.

It fits right into setups that follow a zero-trust model, where every service needs to prove its identity before talking to anything else. Our platform helps enforce that by making sure every service has a valid, short-lived certificate, without requiring your team to get involved every time something changes.

Our CertSecure Manager was designed with cloud-native platforms in mind. It works smoothly with Kubernetes and connects with secret managers like HashiCorp Vault or your internal PKI. Whether you’re using a built-in mesh Certificate Authority or plugging into an external one, our platform can handle it.

The idea is simple: your services keep moving, scaling, and deploying, and our platform keeps their identities secure without slowing anything down. No guesswork, no expired certs, no surprise outages. Just automated certificate management that actually keeps up.

How CertSecure Manager Streamlines mTLS in Service Meshes

Our CertSecure Manager was built to do one job really well: make mTLS in service meshes something you don’t have to think about. It takes care of the messy parts of certificate management so your services can stay secure without constant handholding. Here’s how it works:

Automated Certificate Provisioning for Services

As new services come online, our platform talks to your orchestrator or service registry to figure out who they are and what they need. It then automatically issues identity-bound certificates tied to that specific service instance. No ticket queues, no copy-pasting from a CA, no delays. The moment a service is ready, it gets its cert and can start communicating securely.

Zero-Touch Certificate Renewal and Rotation

Short-lived certs are great for security, but a nightmare if you have to babysit them. Our platform keeps track of expiry dates and rotates certificates well before they expire. Everything happens in the background: no restarts, no downtime, and no surprises during a Friday evening deployment. Your services stay trusted without anyone needing to log in and do it manually.

Centralized Visibility and Policy Enforcement

With our platform, you get a single place to see what’s going on. You can track which services have which certificates, when they expire, and whether they follow your rules. Want to enforce a 90-day validity limit? Prefer 4096-bit keys? Our CertSecure Manager lets you set those policies once and makes sure every cert follows them automatically.

Fast Revocation for Compromised Services

If something goes wrong, like a service gets compromised or starts behaving strangely, you can revoke its certificate immediately through our platform. It doesn’t stop there: our CertSecure Manager can also trigger a sidecar reload or redeploy the pod to make sure the new certificate is picked up cleanly. No gaps, no leftover trust hanging around.

Benefits of Using CertSecure Manager for mTLS in Microservices

Managing mTLS the old-fashioned way, scripts, spreadsheets, or tribal knowledge—just doesn’t hold up when your microservices start multiplying. Our CertSecure Manager makes things simpler, faster, and a whole lot safer. Here’s what you get out of the box:

Reduced Operational Overhead: No more chasing expiring certificates, debugging broken mTLS handshakes, or waking up at 2 a.m. to restart services. Our platform automates the whole process so your teams can stop worrying about certs and focus on shipping features.
Faster Deployments with Secure Defaults: Our platform helps you bake security right into your workflows. As new services spin up, they get valid certs with the right policies, no manual steps, no guesswork. That means you can move faster without cutting corners.
Improved Visibility and Compliance Posture: Need to show which services have valid certs? When do they expire? What algorithms do they use? Our platform gives you a clean, central view of all that. It also helps you stick to internal security rules without needing a weekly audit scramble.
Seamless DevOps Integration: Our platform plays well with your existing DevOps stack. Whether you’re using CI/CD pipelines, GitOps, Helm charts, or something else, CertSecure Manager can plug right in and handle certs automatically as part of your deployments. It’s security that fits into your workflow, not the other way around.

Conclusion

mTLS is essential if you want secure communication between services, especially in dynamic, containerized environments. But keeping track of certificates, manually issuing them, renewing them, and revoking them isn’t just tedious, it’s risky. One missed cert can break everything or worse, open the door to an attack.

Our CertSecure Manager was built to solve this exact problem. It takes the pain out of certificate lifecycle management by automating the entire process from provisioning to revocation without slowing your teams down. Whether you’re running on Kubernetes with Istio and Envoy, integrating with Vault, or managing your own internal PKI, our platform makes mTLS easy, reliable, and hands-off.

If your microservices are growing and you’re still managing certs by hand, it’s time for a change. Let our CertSecure Manager keep your services trusted, your traffic encrypted, and your teams focused on what really matters—building great software.

Your Guide to Secure Code Signing

Software truly serves as the backbone of nearly every industry and personal interaction in our lives. Whether it’s the apps on your phone or the operating systems that keep our essential infrastructure running smoothly, the integrity and authenticity of software are incredibly important.

This is where code signing comes into play—it’s a vital security measure that acts like a digital seal of approval, giving users confidence that the software they download, and use is completely legitimate and hasn’t been altered in any way. Code signing process typically uses robust cryptographic algorithms like RSA (Rivest–Shamir–Adleman) and ECC (Elliptic Curve Cryptography) to ensure this security.

When a software lacks proper code signing, it loses its credibility as it can’t provide proof for its source, which makes it easily vulnerable to tampering, which may result in malware distribution, phishing attacks, and serious reputational harm for developers and organizations. We’ve seen just how serious this can be with real-world incidents like the SolarWinds attack (attackers messed with trusted software before it even reached users), the MSI Data Theft (private keys were compromised for MSI’s firmware across 57 products), and many more.

Now, let’s dive into the essentials of secure code signing together! We’ll explore its benefits, potential drawbacks, and share best practices to strengthen your software supply chain.

Benefits of Code Signing

Code signing is a cryptographic process that authenticates executable files, scripts, and software artifacts by applying a digital signature. This signature is created using a private key and a cryptographic hash of the software. When users run signed software, their operating system verifies the signature with the public key.

Implementing secure code signing practices offers a multitude of benefits for both software developers and end-users:

Verifiable origin and integrity

Code signing establishes a secure link between software and its creator. If an attacker compromises the build pipeline or distribution channel to inject malicious code, the digital signature becomes invalid, alerting to tampering. The verification process checks the digital signature against the software’s unique hash to make sure nothing has been altered since it was signed. This makes it difficult for the attackers to execute advanced supply chain attacks with legitimate software.

Bypassing security warnings and blocks

Modern operating systems and browsers, such as Windows SmartScreen, macOS Gatekeeper, and Chrome’s download protection, check for digital signatures. Unsigned software triggers aggressive security warnings, “unknown publisher” alerts, or is blocked. Secure code signing enables smooth installations without user intervention, greatly improving download-to-install conversion rates. It’s important to remember that while code signing confirms the software hasn’t been tampered with and comes from a verified publisher, it doesn’t guarantee the software itself is completely safe or free of vulnerabilities.

Comply with industry standards

Many industries, especially those handling sensitive data (e.g., healthcare, finance), face strict regulatory requirements regarding software integrity, authenticity, and security. Code signing is essential for compliance with standards like NIST Cybersecurity Framework, SOC 2, HIPAA, PCI DSS, and ISO 27001. Beyond just meeting these regulations, different platforms also enforce code signing in their own ways; for instance, Apple requires macOS apps to undergo a process called ‘notarization’ to ensure they’re checked and signed, and Windows drivers similarly often need to be signed by Microsoft to function correctly.

Best Practices for Secure Code Signing

To really unlock the benefits of code signing, organizations should embrace a set of important practices and strategies. These aren’t just friendly suggestions; they’re essential steps for ensuring the integrity and trustworthiness of your software.

Let’s learn about these key practices, their benefits, and the repercussions of not following them:

Protocol	Benefit	Repercussions of Not Following
Secure Private Key Storage (HSMs)	Private key protection is crucial for code signing. Storing them in certified Hardware Security Modules (HSMs), which are tamper-proof and prohibit private key export, provides strong protection against theft. Using HSMs also provides a strong key backup and disaster recovery strategy to ensure you can still access your keys even if an HSM fails or is lost.	Storing private keys on general-purpose computers (e.g., developer workstations) makes them vulnerable to theft. A compromised key can sign malicious code, resulting in malware distribution and reputational damage. This risk is also present if your keys aren’t strong enough because you’ve chosen outdated algorithms or too-small key sizes, like 1024-bit RSA, making them easier for attackers to break. Furthermore, even when using specialized hardware like Hardware Security Modules (HSMs), if they don’t meet strict certifications like FIPS 140-2, they might not provide the expected level of security, leaving your valuable keys exposed to similar dangers.
Timestamping	A timestamp verifies that the code was signed during the certificate’s validity, ensuring the signature stays valid even after expiration. Timestamping typically follows the RFC 3161 protocol standard, adding an extra layer of trust and longevity to your code’s digital signature, making it vital for long-term software validation.	Without a timestamp, expired code signing certificates render all previously signed software untrusted, causing warnings and potentially blocking execution. This forces users to download new versions, increasing support overhead.
Strict Access Controls and Least Privilege	Limiting access to code signing keys and systems to only authorized personnel with defined roles (Role-Based Access Control – RBAC) minimizes the attack surface.	Unrestricted access increases the risk of insider threats or external attackers gaining control of the signing process, leading to unauthorized or malicious code being signed. To prevent this, it’s crucial to set up strict Role-Based Access Control (RBAC) policies. This ensures only specific, authorized people get the exact permissions they need for each part of the signing process, greatly reducing the chance of unauthorized access and its serious consequences.
Regular Key Rotation	Periodically rotating code signing keys and using unique keys for different releases or projects reduces the impact of a single key compromise.	If one key is used for all releases and is compromised, all software signed with that key becomes untrusted, potentially requiring mass revocation and re-signing, impacting a vast user base. To significantly reduce this, it’s recommended to use different keys for each product or module whenever that’s feasible.
Code Review and Virus Scanning	Thoroughly reviewing and virus scanning all code before it is signed ensures that no vulnerabilities or malicious elements are present in the source.	Accidentally signing vulnerable or malicious code can lead to security breaches, compromise user data, and severely damage the organization’s brand and legal standing.
Centralized Certificate Management	A centralized system for managing all code signing certificates (issuance, deployment, renewal, revocation) provides complete visibility and control over the signing infrastructure.	Without centralized management, organizations can lose track of their certificates, leading to expired certificates, compliance violations, and a lack of oversight over who is signing what. On the other side, a centralized system makes it easy to keep tabs on all your certificates and keys, enabling automated alerts for upcoming expirations, setting up triggers for renewal, and comprehensive reporting.
Monitoring and Auditing	Implementing robust logging and auditing of all code signing activities, like who signed what, when, from where, allows for prompt detection of suspicious activity and analysis in case of a breach. To make these logs even more powerful for security monitoring and incident response, it’s highly recommended that they be integrated with SIEM (Security Information and Event Management) platforms such as Splunk, Grafana, Prometheus, and many more.	Inadequate monitoring, unauthorized signings, or key compromises can go unnoticed for extended periods, allowing attackers to cause significant damage. It also makes incident response and accountability difficult.
Segregation of Test and Production Signing	Maintaining separate infrastructure, keys, and certificates for test-signing and release-signing environments prevents test compromises from affecting production code.	A less secure test environment could be exploited to compromise production signing keys, leading to widespread malicious code distribution.
Certificate Revocation Policies	Having a clear and efficient process for revoking compromised or unnecessary certificates is critical to mitigate damage quickly. To make this process fast and effective, it’s highly recommended that automated support for Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) be implemented.	If a compromised certificate cannot be swiftly revoked, attackers can continue to sign and distribute malicious software under a trusted identity, prolonging the impact of the breach.

CodeSign Secure and PQC

The looming threat of quantum computers presents a significant challenge to current cryptographic algorithms like RSA and ECC, which form the backbone of today’s code signing. But the transition to quantum-resistant cryptography is no longer a distant future. Our CodeSign Secure solution is fully equipped to integrate and utilize the newly approved Post-Quantum Cryptography (PQC) algorithms.

We have been at the forefront of tracking NIST’s PQC standardization efforts and have successfully integrated the quantum-resistant signature algorithms, such as ML-DSA and LMS, directly into CodeSign Secure, meaning organizations will now be able to:

Sign their software with NIST-approved quantum-resistant algorithms
Implement hybrid signing strategies, i.e., combining traditional algorithms (like RSA or ECC) with a quantum-resistant one (like ML-DSA or LMS) within the same software package, giving you strong security now and against future quantum threats.

CodeSign Secure with PQC establishes your organization as a leader in cybersecurity, showing a commitment to the integrity and authenticity of your software supply chain. Adopting this technology now is a smart, proactive move, especially for securing long-lifecycle firmware or addressing national security concerns, as it protects your software against the quantum computer threats of the future, right now.

Conclusion

In this interconnected world, secure code signing is essential for any organization developing or distributing software. By understanding core principles, adopting best practices, and using advanced solutions like CodeSign Secure, developers and businesses can protect their software from tampering, enhance user trust, and safeguard their reputation online.

Remember, the goal is not just to sign code, but to sign it securely. By adhering to strong protocols, protecting your private keys, and staying vigilant to cyber threats, you can ensure that your digital creations remain authentic, untampered, and a source of confidence for every user.

Securing the Software Supply Chain with CodeSign Secure

Introduction

When you think of software security, the first things that come to mind are probably firewalls, antivirus, or maybe patching bugs. But today, the biggest risks don’t always come from the code you write. They come from the code you use, the tools you trust, and the systems that build and deliver your applications.

The software supply chain connects everything: your source code, open-source libraries, CI/CD pipelines, build servers, cloud infrastructure, and even the identities used by your automation tools. And if just one of these links is tampered with, attackers can sneak in and compromise the entire product without ever touching your actual codebase.

We’ve seen this play out with attacks like SolarWinds and Codecov. A single compromised update or leaked secret opened the door to massive damage across thousands of organizations. These aren’t just technical issues; they’re security failures that can cost companies trust, money, and time.

With software moving fast and relying heavily on third-party components, protecting the supply chain security is a basic requirement. It’s not about adding extra steps; it’s about making sure what gets delivered is exactly what was intended, and nothing more.

In this article, we’ll break down how supply chain threats happen, where the weak points are, and what you can do to secure the entire process from writing code to shipping it.

What Exactly is the Software Supply Chain?

Think of the software supply chain like putting together a meal; not everything on your plate was made from scratch. You might’ve chopped the veggies yourself, but the sauce came from a jar, the spices were pre-packaged, and someone else handled the delivery. Software works the same way.

When a developer builds an application, it’s not just their own code that ends up in the final product. There are open-source libraries, third-party tools, APIs, build systems, container images, deployment platforms, and scripts, basically a whole bunch of moving parts that all come together to make software work.

These parts are pulled from different places, often automatically, and stitched together by CI/CD pipelines. There’s also input from people developers, DevOps engineers, security teams, and machines, like automated bots or service accounts that move things along behind the scenes.

All of this, the code, the tools, the infrastructure, the people, and the automation, is your software supply chain.

And just like with food safety, if one ingredient is contaminated or mishandled, it can mess up the entire dish. That’s why understanding what’s in your software and how it gets built and shipped is such a big deal.

How Software Supply Chain Attacks Actually Happen

Software supply chain attacks aren’t some distant, movie-style threat—they’re surprisingly real and, honestly, not that complicated. Attackers don’t always come crashing through your firewalls. Instead, they quietly slip in through the tools, libraries, or systems your team already trusts.

Here’s how it usually plays out:

Target the Dependencies: Most modern apps rely on open-source packages. Attackers sneak malicious code into those packages either by taking over abandoned ones or submitting harmful updates that seem useful. If you pull that package into your build, the attack rides along.

Compromise the Build Pipeline: Instead of hacking your app directly, attackers aim for the systems that build or deploy it, like your CI/CD pipeline. A leaked token, a misconfigured script, or even a vulnerable plugin can give them access to inject code right before release.

Steal or Leak Secrets: APIs, databases, and cloud platforms all use tokens and credentials. When these secrets end up in source code or logs (which happens more often than you’d think), attackers can grab them and gain access without setting off any alarms.

Fake the Source or the Author: In some cases, attackers pretend to be trusted contributors, submitting code that looks totally harmless. If that code gets approved, it becomes part of your product. No alarms. No red flags. Just a quiet backdoor waiting to be used.

Hijack a Dependency at the Registry Level: If an attacker takes over a package registry account (npm, PyPI, etc.), they can push fake versions of widely used tools. Thousands of apps could unknowingly download and use infected versions.

In short, it’s not always about breaking things; it’s about blending in, looking legit, and letting your systems do the rest. And once the malicious code is in, it can go undetected for months.

SolarWinds, Codecov & More: Lessons from High-Impact Breaches

Sometimes, it takes a major incident to shake things up, and in the world of software supply chain security, a few attacks have done exactly that.

SolarWinds

In late 2020, attackers slipped malicious code into a legitimate software update for SolarWinds’ Orion platform. That update went out to thousands of customers, including big-name government agencies and enterprises. What made this scary? The attackers didn’t hack each target they got in through the software they already trusted.

Lesson: Just because code comes from a trusted vendor doesn’t mean it’s clean. If your build process isn’t locked down end-to-end, you’re leaving the door wide open.

Codecov

In 2021, attackers got access to Codecov’s Bash Uploader script by tampering with their Docker image. This tool was used by thousands of developers in CI pipelines. The malicious version quietly sent environment variables, including secrets, to a remote server.

Lesson: Even a small change to a tool in your CI/CD pipeline can leak sensitive information to attackers. Anything that touches credentials or builds deserves extra attention.

Other Examples Worth Noting

Event-Stream (npm): An attacker got access by offering to help maintain an abandoned package, then added malware targeting crypto wallets.

UAParser.js (npm): A popular JavaScript library was hijacked to spread malware to systems that installed it.

Lesson: If a package is public, unattended, or widely used, it’s a tempting target. Attackers love it when you trust packages without checking what’s inside.

From Source Code to Deployment, Where the Weak Spots Are

Building software is like running a relay race; your code passes through a bunch of checkpoints before it reaches production. The problem? Every one of those handoffs is a chance for something to go wrong if you’re not paying close attention.

Here’s a breakdown of where things often slip through the cracks:

Source Code Repos: It starts with the code. But who has access? Are branches protected? If someone pushes a change straight to main without review, or worse, gets access with a stolen token, you’ve got trouble before the build even begins.

Dependencies: Your project probably relies on hundreds of external packages. Some might be outdated, some unmaintained, and some might even have hidden malware. It’s easy to add a dependency. It’s harder to keep track of what each one brings in.

CI/CD Pipelines: These automate your builds, tests, and deployments, which is great. But they also handle secrets, run scripts, and talk to production systems. If one job in the pipeline gets compromised, attackers could inject code or leak sensitive data without being noticed.

Build Artifacts: Once your app is built, the output of your container image, binary, or package is usually trusted without question. But if that artifact isn’t signed or verified, there’s no way to tell if it’s legit or tampered with.

Deployment Systems: Kubernetes, Terraform, and GitOps tools all help ship software quickly. But they can also be a backdoor if misconfigured. A single exposed API or misused service account can lead straight to production.

Each stage seems simple on its own, but together, they make up a long, interconnected chain. And like any chain, it’s only as strong as the weakest link. That’s why security needs to be part of every step, not something that gets bolted on at the end.

Why CI/CD Pipelines Have Become a Favourite Attack Target

CI/CD pipelines are the beating heart of modern software delivery. They build your code, run your tests, sign your artifacts, and push everything to production automatically. That’s a lot of power in one place. And guess what? Attackers have definitely noticed.

High Access, Low Visibility: CI/CD tools often have more access than most developers. They can pull code, use secrets, and deploy them to production, all without human input. That makes them a goldmine for attackers. And because most of it happens behind the scenes, malicious changes can go undetected for a while.

Secrets Stored in Plain Sight: CI/CD environments usually need credentials for things like cloud access, signing keys, and APIs. But if those secrets are stored as plain text, misconfigured, or over-permissioned, they’re low-hanging fruit for attackers who gain access to the pipeline.

Many Tools, Many Gaps: The pipeline isn’t just one tool; it’s a mix of Git platforms, runners, plugins, package managers, cloud services, and more. If any part of that chain is insecure or unpatched, it opens the door. Attackers don’t need to break everything. Just one piece is enough.

Exploiting Automation: Once attackers sneak into the pipeline, they can automate the damage. Slip malware into a build, change environment variables, or send secrets to an external server, all without needing constant access. The pipeline does the work for them.

Why You Should Care

If an attacker compromises your CI/CD pipeline, they can ship malicious updates straight to your users. No warnings. No alerts. Just a clean-looking deployment with something nasty baked in.

CI/CD makes shipping code fast and smooth, but without proper controls, it also makes attacks fast and silent. Securing the pipeline isn’t just a DevOps job anymore; it’s a security priority.

Code Signing Done Right

Code signing is like putting a wax seal on your software package. It proves the code really comes from you and hasn’t been messed with along the way. Without proper code signing, anyone could slip malicious code into your app or update. That means users might install something dangerous without knowing it.

Signing your code adds a layer of trust. It tells users and systems, “This is the real deal, safe to run.” It also helps with compliance. Many regulations require proof that software hasn’t been tampered with during delivery. But it’s not just about slapping on a signature. It’s about doing it right using secure keys, protecting those keys, and integrating signing into your build and release pipeline. If code signing is clunky or manual, people skip it or mess it up. That creates risks.

Doing it right means automation, strong cryptography, and clear policies.

In today’s software world, where attacks can come from inside your supply chain, strong code signing is a must-have, not a nice-to-have.

SBOMs, Attestations, and Gaining Visibility Across the Chain

When it comes to software supply chains, you can’t protect what you can’t see. That’s where things like SBOMs and attestations come into play; they give you a clear picture of what’s inside your software and how it got there.

What’s an SBOM, Anyway?

SBOM stands for Software Bill of Materials. Think of it as an ingredient list for your software, showing every component, library, and dependency that’s bundled together. It helps teams spot vulnerabilities quickly and makes compliance a lot easier.

Why Are Attestations Important?

Attestations are like digital receipts confirming certain steps happened during your build or release process. For example, an attestation might prove your code was scanned for vulnerabilities or that it was signed by a trusted key.

Seeing the Whole Chain

Together, SBOMs and attestations give you better insight into what’s inside your apps and how they were built. This visibility helps catch problems early, avoid risks, and respond faster if something does go wrong.

Better Transparency, Better Security

When you know exactly what’s running in production, and you have proof that your code passed through the right checks, it’s easier to trust your software and easier to prove it to customers and auditors, too.

Compliance-Ready Security: Meeting SLSA, NIST, SSDF, and CRA

Keeping your software supply chain secure isn’t just good practice; it’s often a must to meet industry standards and regulations. That’s where frameworks like SLSA, NIST SSDF, and CRA come in.

What Are These Frameworks?

SLSA (Supply-chain Levels for Software Artifacts) is a checklist to make sure your build processes are trustworthy and protected from tampering.

NIST SSDF (Secure Software Development Framework) offers guidelines on building security into your development lifecycle, focusing on reducing risks in software delivery.

CRA (Cybersecurity Risk Assessment) helps organizations identify and manage risks across their software supply chain.

Why Do They Matter?

Following these frameworks means you’re taking concrete steps to lock down your pipeline and protect your software. They provide clear, actionable guidance so you’re not just guessing what to secure.

How CodeSign Secure Helps

Platforms like our CodeSign Secure make ticking off these boxes easier. By automating code signing and artifact attestation, our platform supports your compliance efforts without adding extra manual work.

At the end of the day, following these standards helps you build trust with your customers, partners, and auditors, all while keeping the bad guys out.

Conclusion

The software supply chain isn’t just about writing clean code anymore. It’s about knowing what goes into your builds, how your software is assembled, and being able to prove that nothing shady happened along the way.

Attackers are getting smarter and they’re aiming at the tools and automation you rely on every day. Whether it’s a compromised dependency, a leaky CI job, or a sneaky unsigned artifact, small gaps can lead to big problems.

That’s why visibility, signing, and traceability aren’t optional anymore. They’re the baseline.
