Learn How Code Signing Can Impact Your Organization

Reading Time : 5 minutes

Code signing is a technique used to ensure the authenticity and integrity of software code. This technique involves digitally signing the code with a digital signature, which can be verified by the user to ensure that the code has not been modified or tampered with. Code signing is an essential security measure for any organization that develops or distributes software, as it helps to prevent unauthorized code from being installed on users’ systems. In this blog, we will explore the importance of code signing and its impact on your organization.

What is Code Signing?

Code signing is the process of digitally signing software code to ensure its authenticity and integrity. A digital signature is a mathematical algorithm that uses a private key to encrypt the code and a public key to decrypt it. This signature ensures that the code has not been modified or tampered with since it was signed.

Code signing is done using a digital certificate issued by a trusted certificate authority (CA). The digital certificate contains information about the signer and the code being signed, and it is used to verify the signature’s authenticity. When the code is installed on a user’s system, it checks the digital signature against the certificate to ensure it has not been tampered with.

Why is Code Signing Important?

Code signing is essential for several reasons. Firstly, it ensures the authenticity and integrity of software code. This means that users can trust that the code they are installing is from a trusted source and has not been tampered with. This is particularly important for software that is used to handle sensitive data, such as financial or healthcare data.

Secondly, code signing helps prevent malware and other malicious code from being installed on users’ systems. Malware often tries to disguise itself as legitimate software, and code signing helps to prevent this by providing users with a way to verify the authenticity of the code they are installing.

Finally, code signing is often a requirement for software vendors that want to distribute their software through trusted channels, such as app stores or enterprise software distribution platforms. These platforms often require that software be signed with a trusted digital certificate to ensure its authenticity and security.

How does Code Signing impact your organization?

Code signing can have a significant impact on your organization. Here are some of the keyways that code signing can impact your organization:

• Enhanced Security

  Code signing can help to enhance the security of your organization’s software. Signing your code with a trusted digital certificate ensures that only legitimate code is installed on users’ systems. This can help prevent malware and other malicious code from infecting your organization’s network.

• Compliance

  Many regulatory bodies require that software be signed with a trusted digital certificate to ensure its authenticity and security. Signing your software with a trusted digital certificate ensures that your organization complies with these regulations. This can help to avoid costly fines and legal issues.

• Brand Protection

  Code signing can help to protect your organization’s brand. Signing your software with a trusted digital certificate ensures that users trust the software they are installing. This can help to protect your organization’s reputation and prevent damage to your brand.

• Increased User Confidence

  Code signing can increase user confidence in your organization’s software. By signing your software with a trusted digital certificate, you can provide users with a way to verify the authenticity and integrity of the software they are installing. This can help to increase user confidence in your organization’s software and lead to increased adoption.

• Reduced Support Costs

  Code signing can help to reduce support costs for your organization. By ensuring that only legitimate software is installed on users’ systems, you can reduce the likelihood of software-related issues. This can help to reduce the number of support requests your organization receives, leading to lower support costs.

To ensure that your organization maximizes the benefits of code signing, there are several best practices which can be followed:

• Use a Trusted Certificate Authority

  To ensure that your digital certificate is trusted by users, it is important to use a trusted certificate authority (CA) to issue your certificate. Trusted CAs are widely recognized and trusted by most operating systems and web browsers, ensuring that users can verify the authenticity of your code.

• Keep Your Private Key Secure

  Your private key is used to sign your software code, and it must always remain secure. If your private key is compromised, an attacker could use it to sign and distribute malicious code that appears to be from your organization. To prevent this, ensure that your private key is stored securely, and that only authorized personnel have access to it.

• Sign All Code

  To ensure maximum security, it is important to sign all of your organization’s software code, including drivers, DLLs, and other executables. This ensures that users can verify the authenticity and integrity of all your code, not just the main executable.

• Timestamp Your Signature

  When you sign your code, including a timestamp to indicate when the code was signed is important. This ensures that users can verify that the code was signed before a specific date, helping to prevent attacks that rely on the compromise of older signed code.

• Use Strong Passwords

  When generating your private key, it is important to use a strong password to prevent unauthorized access. A strong password should be long, complex, and unique and should be changed regularly to ensure maximum security.

• Verify Your Signature

  Before distributing your code, it is important to verify your signature to ensure that it is valid. This ensures that users will be able to verify your signature when they install your software.

• Revoke Certificates as Necessary

  If your private key is compromised or if you need to revoke a certificate for any reason, it is important to do so immediately. This ensures that users will not trust any code signed with the compromised or revoked certificate.

How can Encryption Consulting (EC) CodeSign Secure help you?

EC has developed the most efficient and user-friendly code-signing solution, CodeSign Secure. What makes us the best out in the market?

• CodeSign Secure starts with virus scanning before commencing any type of signing process. It searches for any viruses or malware that may have been injected into the file before sending it away for the signing process.

• CodeSign secure uses client-side hashing, providing customers with that extra layer of security. Hashing a file at its origin helps maintain its integrity at its peak and gives the customer a clear view of the file and what comes after signing.

• Never exposing the key while signing the file/code. The file is signed inside the HSM, and the keys are never exposed to the outside world.
• Our organization provides Role-based access control for code/file signing providing correct access and privileges to the user. Ensuring only those with proper roles can access certificates and keys within the tool.
• Timestamp your signed code avoids the risks of software expiring unexpectedly when the code signing certificate expires. When a code signing certificate expires, the validity of the software that was signed will also expire unless the software was timestamped when it was signed.
• CodeSign Secure follows the latest NIST (National Institute of Standards and Technology) guidelines of code signing
• Monitor and audit key signing workflows, certificates and keys are associated with specific applications, and whoever is signing anything gets recorded in the logs of our tool, so we have the IP and the username of anyone attempting to sign. They will be blocked if they do not have valid credentials, or the key or certificate has expired.
• Enable automated code signing in SDLC processes, we have the ability to sign from a client tool, via APIs, or via the command line so it is very straightforward and simple to integrate our tool into SDLC processes, including tools like Jenkins and Bamboo.
• Compare signing from different build servers, our tool will check that the code being signed is the most up to date version of the code on the build servers in use by the client, ensuring an older or potentially malicious version of the code is not being signed.
• Revoking compromised certificates, when a certificate expires, it will automatically be renewed, but in the case that a certificate or key is found to have been compromised, the key can be revoked and thus the signing process cannot occur with that key and certificate.

Conclusion

Code signing is an essential security measure for any organization that develops or distributes software. It helps to ensure the authenticity and integrity of software code, preventing unauthorized code from being installed on users’ systems. Code signing can significantly impact your organization, enhancing security, ensuring compliance, protecting your brand, increasing user confidence, and reducing support costs.

To ensure that your organization maximizes the benefits of code signing, it is important to follow best practices such as using a trusted certificate authority, keeping your private key secure, signing all code, timestamping your signature, using strong passwords, verifying your signature, and revoking certificates as necessary.
