SC-38 Operations Security
High-Level Description
Family: System and Communications Protection (SC)
Framework: NIST SP 800-53 Rev 5
Operations security (OPSEC) is a systematic process by which potential adversaries can be denied information about the capabilities and intentions of organizations by identifying, controlling, and protecting generally unclassified information that specifically relates to the planning and execution of sensitive organizational activities. The OPSEC process involves five steps: identification of critical information, analysis of threats, analysis of vulnerabilities, assessment of risks, and the application of appropriate countermeasures. OPSEC controls are applied to organizational systems and the environments in which those systems operate. OPSEC controls protect the confidentiality of information, including limiting the sharing of information with suppliers, potential suppliers, and other non-organizational elements and individuals. Information critical to organizational mission and business functions includes user identities, element uses, suppliers, supply chain processes, functional requirements, security requirements, system design specifications, testing and evaluation protocols, and security control implementation details.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-38 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.
