PW.4.1 PW.4.1
Task of practice: Reuse Existing, Well-Secured Software When Feasible Instead of Duplicating Functionality (PW.4)
High-Level Description
Practice Group: Produce Well-Secured Software (PW)
Framework: NIST SP 800-218 SSDF v1.1
Acquire and maintain well-secured software components (e.g., software libraries, modules, middleware, frameworks) from commercial, open-source, and other third-party developers for use by the organization’s software.
What to Check
How to Test
Step 1: Review SDLC Documentation
Examine development lifecycle documentation for evidence of PW.4.1 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 PW.4.1 PW.4.1 practice.
