SR-9(1) Multiple Stages of System Development Life Cycle

Enhancement of: SR-9

High-Level Description

Family: Supply Chain Risk Management (SR) Framework: NIST SP 800-53 Rev 5

The system development life cycle includes research and development, design, manufacturing, acquisition, delivery, integration, operations and maintenance, and disposal. Organizations use a combination of hardware and software techniques for tamper resistance and detection. Organizations use obfuscation and self-checking to make reverse engineering and modifications more difficult, time-consuming, and expensive for adversaries. The customization of systems and system components can make substitutions easier to detect and therefore limit damage.

What to Check

• Verify SR-9(1) Multiple Stages of System Development Life Cycle is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SR-9(1)
• Verify enhancement builds upon base control SR-9

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SR-9(1) implementation details. Verify the organization has documented how this control is satisfied.

Step 2: Validate Implementation

# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null

Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
