PCI DSS 4.0 Requirements: Secure SDLC Libraries and End-of-Life (EOL) Software Compliance

Introduction

As part of the latest updates in PCI DSS 4.0, businesses must enhance their security posture by ensuring the use of secure software development lifecycle (SDLC) libraries and phasing out End-of-Life (EOL) software. These requirements aim to mitigate risks associated with outdated or vulnerable software components that could compromise cardholder data security.

This blog explores the new PCI DSS 4.0 mandates for secure SDLC libraries and EOL software, providing actionable insights for compliance.

PCI DSS 4.0 Requirements for Secure SDLC Libraries

What are SDLC Libraries?

Software Development Lifecycle (SDLC) libraries include third-party and open-source components used in application development. These libraries provide essential functionalities, but they can introduce security risks if not properly managed.

Key PCI DSS 4.0 Requirements for SDLC Libraries

To align with PCI DSS 4.0, organizations must:

Maintain an Inventory of SDLC Libraries – Keep a comprehensive list of all libraries, frameworks, and dependencies used in software applications.
Ensure Libraries are Regularly Updated – Adopt a proactive approach to updating software libraries with security patches and latest releases.
Monitor Vulnerability Databases – Continuously monitor sources like NVD (National Vulnerability Database) and vendor security bulletins for emerging threats.
Utilize Approved and Secure Libraries – Implement security-approved repositories and restrict the use of outdated or unverified components.
Automate Dependency Scanning – Employ Software Composition Analysis (SCA) tools to detect and remediate vulnerabilities in third-party dependencies.
Enforce Secure Coding Practices – Developers must follow secure coding guidelines and minimize reliance on insecure third-party libraries.

How to Implement Secure SDLC Library Management?

Use dependency management tools like OWASP Dependency-Check, Snyk, or GitHub Dependabot to detect outdated or vulnerable components.
Establish an automated update process for library patching and versioning.
Perform security reviews before integrating new libraries into applications.

PCI DSS 4.0 Requirements for End-of-Life (EOL) Software

What is EOL Software?

End-of-Life (EOL) software refers to applications, operating systems, or components no longer receiving vendor support, security updates, or patches. Continuing to use EOL software presents a high-security risk as attackers target known vulnerabilities.

Key PCI DSS 4.0 Requirements for EOL Software

To maintain compliance with PCI DSS 4.0, organizations must:

Identify and Document EOL Software – Conduct regular assessments to detect software nearing or reaching EOL status.
Develop a Migration Plan – Establish a transition roadmap to upgrade or replace outdated software before it becomes a security liability.
Implement Compensating Controls – If EOL software must be used temporarily, deploy additional security controls like network segmentation and monitoring.
Prohibit the Use of Unsupported Components – Ensure that all software handling cardholder data remains within vendor-supported versions.
Regularly Patch and Update Systems – Apply security patches and service packs as soon as they become available.
Monitor EOL Announcements from Vendors – Stay informed about software lifecycle updates from providers like Microsoft, Oracle, and Linux distributions.

How to Manage EOL Software Compliance?

Maintain an asset inventory of software and track vendor support timelines.
Use automated scanning tools to detect EOL components in your infrastructure.
Develop a phased decommissioning plan to retire outdated software.

Business Impact of Non-Compliance

Failing to comply with PCI DSS 4.0 requirements for SDLC libraries and EOL software can lead to:

Increased exposure to security breaches and data leaks.
Regulatory penalties and non-compliance fines.
Loss of customer trust due to compromised payment security.

Conclusion

PCI DSS 4.0 introduces stringent security measures to ensure organizations use secure SDLC libraries and eliminate EOL software risks. By implementing proactive library management, automated vulnerability scanning, and timely software upgrades, businesses can achieve compliance and fortify their security posture.
