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
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.
