IA-13(3) Token Management

Enhancement of: IA-13

High-Level Description

Family: Identification and Authentication (IA) Framework: NIST SP 800-53 Rev 5

An access token is a piece of data that represents the authorization granted to a user or NPE to access specific systems or information resources. Access tokens enable controlled access to services and resources. Properly managing the lifecycle of access tokens, including their issuance, validation, and revocation, is crucial to maintaining confidentiality of data and systems. Restricting token validity to a specific audience, e.g., an application or security domain, and restricting token validity lifetimes are important practices. Access tokens are revoked or invalidated if they are compromised, lost, or are no longer needed to mitigate the risks associated with stolen or misused tokens.

What to Check

• Verify IA-13(3) Token Management is documented in SSP
• Validate all 6 control requirements are implemented
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IA-13(3)
• Verify enhancement builds upon base control IA-13

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IA-13(3) 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

In accordance with [organization-defined], assertions and access tokens are: generated; issued; refreshed; revoked; time-restricted; and audience-restricted.
