SA-4(6) Use of Information Assurance Products
Enhancement of: SA-4
High-Level Description
Family: System and Services Acquisition (SA) Framework: NIST SP 800-53 Rev 5
Commercial off-the-shelf IA or IA-enabled information technology products used to protect classified information by cryptographic means may be required to use NSA-approved key management. See NSA CSFC.
What to Check
- Verify SA-4(6) Use of Information Assurance Products is documented in SSP
- Validate all 2 control requirements are implemented
- Confirm control is operating effectively
- Review evidence of continuous monitoring for SA-4(6)
- Verify enhancement builds upon base control SA-4
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SA-4(6) 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.

Control Statement
Employ only government off-the-shelf or commercial off-the-shelf information assurance and information assurance-enabled information technology products that compose an NSA-approved solution to protect classified information when the networks used to transmit the information are at a lower classification level than the information being transmitted; and Ensure that these products have been evaluated and/or validated by NSA or in accordance with NSA-approved procedures.
Implementation Guidance
Commercial off-the-shelf IA or IA-enabled information technology products used to protect classified information by cryptographic means may be required to use NSA-approved key management. See NSA CSFC.
