IA-5(13) Expiration of Cached Authenticators
Enhancement of: IA-5
High-Level Description
Family: Identification and Authentication (IA)
Framework: NIST SP 800-53 Rev 5
Cached authenticators are used to authenticate to the local machine when the network is not available. If cached authentication information is out of date, the validity of the authentication information may be questionable.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IA-5(13) 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
Prohibit the use of cached authenticators after [organization-defined].
Implementation Guidance
Cached authenticators are used to authenticate to the local machine when the network is not available. If cached authentication information is out of date, the validity of the authentication information may be questionable.
