SA-10(6)_trusted-distribution

SA-10(6) Trusted Distribution

Enhancement of: SA-10

High-Level Description

Family: System and Services Acquisition (SA) Framework: NIST SP 800-53 Rev 5

The trusted distribution of security-relevant hardware, software, and firmware updates help to ensure that the updates are correct representations of the master copies maintained by the developer and have not been tampered with during distribution.

What to Check

• Verify SA-10(6) Trusted Distribution is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SA-10(6)
• Verify enhancement builds upon base control SA-10

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-10(6) 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

Require the developer of the system, system component, or system service to execute procedures for ensuring that security-relevant hardware, software, and firmware updates distributed to the organization are exactly as specified by the master copies.

Implementation Guidance

The trusted distribution of security-relevant hardware, software, and firmware updates help to ensure that the updates are correct representations of the master copies maintained by the developer and have not been tampered with during distribution.
