IA-8(5) Acceptance of PIV-I Credentials

Enhancement of: IA-8

High-Level Description

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

Acceptance of PIV-I credentials can be implemented by PIV, PIV-I, and other commercial or external identity providers. The acceptance and verification of PIV-I-compliant credentials apply to both logical and physical access control systems. The acceptance and verification of PIV-I credentials address nonfederal issuers of identity cards that desire to interoperate with United States Government PIV systems and that can be trusted by Federal Government-relying parties. The X.509 certificate policy for the Federal Bridge Certification Authority (FBCA) addresses PIV-I requirements. The PIV-I card is commensurate with the PIV credentials as defined in cited references. PIV-I credentials are the credentials issued by a PIV-I provider whose PIV-I certificate policy maps to the Federal Bridge PIV-I Certificate Policy. A PIV-I provider is cross-certified with the FBCA (directly or through another PKI bridge) with policies that have been mapped and approved as meeting the requirements of the PIV-I policies defined in the FBCA certificate policy.

What to Check

• Verify IA-8(5) Acceptance of PIV-I Credentials is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IA-8(5)
• Verify enhancement builds upon base control IA-8

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IA-8(5) 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.
