SC-16(1) Integrity Verification

Enhancement of: SC-16

High-Level Description

Family: System and Communications Protection (SC) Framework: NIST SP 800-53 Rev 5

Part of verifying the integrity of transmitted information is ensuring that security and privacy attributes that are associated with such information have not been modified in an unauthorized manner. Unauthorized modification of security or privacy attributes can result in a loss of integrity for transmitted information.

What to Check

• Verify SC-16(1) Integrity Verification is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SC-16(1)
• Verify enhancement builds upon base control SC-16

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-16(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.
