SA-15(6)_continuous-improvement

SA-15(6) Continuous Improvement

Enhancement of: SA-15

High-Level Description

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

Developers of systems, system components, and system services consider the effectiveness and efficiency of their development processes for meeting quality objectives and addressing the security and privacy capabilities in current threat environments.

What to Check

• Verify SA-15(6) Continuous Improvement is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SA-15(6)
• Verify enhancement builds upon base control SA-15

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-15(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 implement an explicit process to continuously improve the development process.

Implementation Guidance

Developers of systems, system components, and system services consider the effectiveness and efficiency of their development processes for meeting quality objectives and addressing the security and privacy capabilities in current threat environments.
