SA-17(8)_orchestration

SA-17(8) Orchestration

Enhancement of: SA-17

High-Level Description

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

Security resources that are distributed, located at different layers or in different system elements, or are implemented to support different aspects of trustworthiness can interact in unforeseen or incorrect ways. Adverse consequences can include cascading failures, interference, or coverage gaps. Coordination of the behavior of security resources (e.g., by ensuring that one patch is installed across all resources before making a configuration change that assumes that the patch is propagated) can avert such negative interactions.

What to Check

• Verify SA-17(8) Orchestration is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SA-17(8)
• Verify enhancement builds upon base control SA-17

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-17(8) 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.

Implementation Guidance

Security resources that are distributed, located at different layers or in different system elements, or are implemented to support different aspects of trustworthiness can interact in unforeseen or incorrect ways. Adverse consequences can include cascading failures, interference, or coverage gaps. Coordination of the behavior of security resources (e.g., by ensuring that one patch is installed across all resources before making a configuration change that assumes that the patch is propagated) can avert such negative interactions.
