SC-34(2) Integrity Protection on Read-only Media

Enhancement of: SC-34

High-Level Description

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

Controls prevent the substitution of media into systems or the reprogramming of programmable read-only media prior to installation into the systems. Integrity protection controls include a combination of prevention, detection, and response.

What to Check

• Verify SC-34(2) Integrity Protection on Read-only Media is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SC-34(2)
• Verify enhancement builds upon base control SC-34

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-34(2) 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.
