IA-12(1)_supervisor-authorization

IA-12(1) Supervisor Authorization

Enhancement of: IA-12

High-Level Description

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

Including supervisor or sponsor authorization as part of the registration process provides an additional level of scrutiny to ensure that the user’s management chain is aware of the account, the account is essential to carry out organizational missions and functions, and the user’s privileges are appropriate for the anticipated responsibilities and authorities within the organization.

What to Check

• Verify IA-12(1) Supervisor Authorization is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IA-12(1)
• Verify enhancement builds upon base control IA-12

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IA-12(1) 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.
