SI-14(1) Refresh from Trusted Sources

Enhancement of: SI-14

High-Level Description

Family: System and Information Integrity (SI) Framework: NIST SP 800-53 Rev 5

Trusted sources include software and data from write-once, read-only media or from selected offline secure storage facilities.

What to Check

• Verify SI-14(1) Refresh from Trusted Sources is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-14(1)
• Verify enhancement builds upon base control SI-14

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-14(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.
