The Enterprise

Challenges

The organization had strong cybersecurity practices and HIPAA compliance, but its code signing operations had gaps that slowed software deployment and put patient care continuity at risk. Unauthorized software downloads, insecure IoT firmware, unsigned code, and macro vulnerabilities compounded the exposure.

Unauthorized downloads compromising infrastructure

Employees downloaded unvetted software to work faster, but these unauthorized installations brought unverified code into the enterprise infrastructure and created serious security risks.

01 Infrastructure

Insecure IoT devices & unprotected firmware

IoT devices ran on outdated, unprotected firmware. Attackers could exploit these gaps to break into networks, take over devices, or launch DDoS attacks, data breaches, and malware campaigns.

02 IoT Security

No code signing leaving software unprotected

Without code signing, the organization could not verify software authenticity or integrity across its network. This weakened overall security and left systems open to malware and malicious code injection.

03 Code Signing

In healthcare, the integrity of every piece of software directly impacts patient data and care continuity. Code signing needed to become a governed, automated process rather than an afterthought.

Our Offered

Solutions

The organization deployed CodeSign Secure to enforce access controls, secure private keys in HSMs, enable macro signing for EHR workflows, unify global key management, and validate code against antivirus definitions before signing.

Capability 01

LDAP Access Control & Workflows

LDAP-integrated authentication with customizable code signing workflows prevented unauthorized access and insider misuse of signing privileges. It also eliminated the risk of code being signed with malicious certificates.

Capability 02

HSM Key Protection & Vendor Integration

FIPS 140-2 validated HSMs secured all private keys under centralized management for visibility and control. Entrust and Thales integration brought together globally scattered keys and certificates that had inconsistent security practices, lifecycle management, and ownership tracking.

Capability 03

32/64-Bit Macro Signing via Luna HSM

A compatibility bridge let the 32-bit signtool work on the 64-bit Windows 10 platform, so the client could securely sign Excel macros used in EHR systems through Luna HSM without losing security or performance standards.

Capability 04

Pre-Sign AV Validation & Unified Keys

Hash validation against current antivirus definitions made sure only clean, trusted code receives a signature. HSM-unified key and certificate management streamlined oversight of globally distributed keys and kept security standards uniform and strong.

The result was a secure, access-controlled code signing process with HSM-backed keys, validated macros for EHR systems, and antivirus-checked signatures, all unified under a single platform.

The Overall

Business Outcome

CodeSign Secure solved the organization's healthcare code signing challenges: software security improved, EHR workflows were protected, and every digitally signed application became more trustworthy.

Unauthorized signing eliminated & access hardened

LDAP controls with customizable workflows restricted signing to verified personnel. This prevented malicious certificate use, reduced the risk of compromise, and made signed applications more trustworthy.

Keys secured & global management unified

HSM-backed storage eliminated the risks of unauthorized access, corruption, and misuse. Entrust and Thales integration standardized practices across global keys and certificates under uniform oversight.

EHR macro signing & code integrity assured

64-bit macro signing via Luna HSM secured daily EHR workflows. Pre-sign AV validation made sure only clean code gets signed, keeping code integrity intact and protecting patient privacy and data.
