# PW.8.1 PW.8.1

> **Task of practice:** Test Executable Code to Identify Vulnerabilities and Verify Compliance with Security Requirements (PW.8)

## High-Level Description

**Practice Group:** Produce Well-Secured Software (PW)
**Framework:** NIST SP 800-218 SSDF v1.1

Determine whether executable code testing should be performed to find vulnerabilities not identified by previous reviews, analysis, or testing and, if so, which types of testing should be used.

## What to Check

- [ ] Verify PW.8.1 PW.8.1 is integrated into SDLC
- [ ] Review CI/CD pipeline for PW.8.1 implementation
- [ ] Confirm automated tooling supports this practice

## How to Test

### Step 1: Review SDLC Documentation

Examine development lifecycle documentation for evidence of PW.8.1 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.8.1 PW.8.1 practice.

## Tools

| Tool                | Purpose                            | Usage                        |
| ------------------- | ---------------------------------- | ---------------------------- |
| github-security-mcp | Check repository security settings | `github_security_*` tools    |
| Manual Review       | SDLC process review                | Documentation and interviews |

## Remediation Guide

Implement PW.8.1 PW.8.1 in the software development lifecycle:

Determine whether executable code testing should be performed to find vulnerabilities not identified by previous reviews, analysis, or testing and, if so, which types of testing should be used.

## Risk Assessment

| Finding                       | Severity | Impact                                             |
| ----------------------------- | -------- | -------------------------------------------------- |
| PW.8.1 PW.8.1 not implemented | Medium   | Secure Development - Produce Well-Secured Software |

## CWE Categories

| CWE ID | Title                     |
| ------ | ------------------------- |
| CWE-20 | Improper Input Validation |
