# PO.5.1 PO.5.1
> **Task of practice:** Implement and Maintain Secure Environments for Software Development (PO.5)
## High-Level Description
**Practice Group:** Prepare the Organization (PO)
**Framework:** NIST SP 800-218 SSDF v1.1
Separate and protect each environment involved in software development.
## What to Check
- [ ] Verify PO.5.1 PO.5.1 is integrated into SDLC
- [ ] Review CI/CD pipeline for PO.5.1 implementation
- [ ] Confirm automated tooling supports this practice
## How to Test
### Step 1: Review SDLC Documentation
Examine development lifecycle documentation for evidence of PO.5.1 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 PO.5.1 PO.5.1 practice.
