CA-7(1)_independent-assessment

CA-7(1) Independent Assessment

Enhancement of: CA-7

High-Level Description

Family: Assessment, Authorization, and Monitoring (CA) Framework: NIST SP 800-53 Rev 5

Organizations maximize the value of control assessments by requiring that assessments be conducted by assessors with appropriate levels of independence. The level of required independence is based on organizational continuous monitoring strategies. Assessor independence provides a degree of impartiality to the monitoring process. To achieve such impartiality, assessors do not create a mutual or conflicting interest with the organizations where the assessments are being conducted, assess their own work, act as management or employees of the organizations they are serving, or place themselves in advocacy positions for the organizations acquiring their services.

What to Check

• Verify CA-7(1) Independent Assessment is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for CA-7(1)
• Verify enhancement builds upon base control CA-7

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CA-7(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.

Control Statement

Employ independent assessors or assessment teams to monitor the controls in the system on an ongoing basis.
