CM-10(1) Open-source Software

Enhancement of: CM-10

High-Level Description

Family: Configuration Management (CM) Framework: NIST SP 800-53 Rev 5

Open-source software refers to software that is available in source code form. Certain software rights normally reserved for copyright holders are routinely provided under software license agreements that permit individuals to study, change, and improve the software. From a security perspective, the major advantage of open-source software is that it provides organizations with the ability to examine the source code. In some cases, there is an online community associated with the software that inspects, tests, updates, and reports on issues found in software on an ongoing basis. However, remediating vulnerabilities in open-source software may be problematic. There may also be licensing issues associated with open-source software, including the constraints on derivative use of such software. Open-source software that is available only in binary form may increase the level of risk in using such software.

What to Check

• Verify CM-10(1) Open-source Software is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for CM-10(1)
• Verify enhancement builds upon base control CM-10

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CM-10(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.
