PS.3.1 PS.3.1

Task of practice: Archive and Protect Each Software Release (PS.3)

High-Level Description

Practice Group: Protect Software (PS) Framework: NIST SP 800-218 SSDF v1.1

Securely archive the necessary files and supporting data (e.g., integrity verification information, provenance data) to be retained for each software release.

What to Check

• Verify PS.3.1 PS.3.1 is integrated into SDLC
• Review CI/CD pipeline for PS.3.1 implementation
• Confirm automated tooling supports this practice

How to Test

Step 1: Review SDLC Documentation

Examine development lifecycle documentation for evidence of PS.3.1 practice implementation.

Step 2: Verify Tooling

# Check CI/CD pipeline configuration
# Verify security tools are integrated

# Example: Check for SAST/DAST in pipeline
grep -r "security\|scan\|sast\|dast" .github/workflows/ 2>/dev/null
grep -r "security\|scan" Jenkinsfile 2>/dev/null

Step 3: Assess Developer Awareness

Verify development team understands and follows PS.3.1 PS.3.1 practice.

Tools

Remediation Guide

Implement PS.3.1 PS.3.1 in the software development lifecycle:

Securely archive the necessary files and supporting data (e.g., integrity verification information, provenance data) to be retained for each software release.
