# Design Software to Meet Security Requirements and Mitigate Security Risks (PW.1) Design Software to Meet Security Requirements and Mitigate Security Risks

## High-Level Description

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

Identify and evaluate the security requirements for the software; determine what security risks the software is likely to face during operation and how the software’s design and architecture should mitigate those risks; and justify any cases where risk-based analysis indicates that security requirements should be relaxed or waived. Addressing security requirements and risks during software design (secure by design) is key for improving software security and also helps improve development efficiency.

## What to Check

- [ ] Verify Design Software to Meet Security Requirements and Mitigate Security Risks (PW.1) Design Software to Meet Security Requirements and Mitigate Security Risks is integrated into SDLC
- [ ] Review CI/CD pipeline for Design Software to Meet Security Requirements and Mitigate Security Risks (PW.1) implementation
- [ ] Confirm automated tooling supports this practice

## How to Test

### Step 1: Review SDLC Documentation

Examine development lifecycle documentation for evidence of Design Software to Meet Security Requirements and Mitigate Security Risks (PW.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 Design Software to Meet Security Requirements and Mitigate Security Risks (PW.1) Design Software to Meet Security Requirements and Mitigate Security Risks 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 Design Software to Meet Security Requirements and Mitigate Security Risks (PW.1) Design Software to Meet Security Requirements and Mitigate Security Risks in the software development lifecycle:

Identify and evaluate the security requirements for the software; determine what security risks the software is likely to face during operation and how the software’s design and architecture should mitigate those risks; and justify any cases where risk-based analysis indicates that security requirements should be relaxed or waived. Addressing security requirements and risks during software design (secure by design) is key for improving software security and also helps improve development efficiency.
