SA-9(5) Processing, Storage, and Service Location

Enhancement of: SA-9

High-Level Description

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

The location of information processing, information and data storage, or system services can have a direct impact on the ability of organizations to successfully execute their mission and business functions. The impact occurs when external providers control the location of processing, storage, or services. The criteria that external providers use for the selection of processing, storage, or service locations may be different from the criteria that organizations use. For example, organizations may desire that data or information storage locations be restricted to certain locations to help facilitate incident response activities in case of information security incidents or breaches. Incident response activities, including forensic analyses and after-the-fact investigations, may be adversely affected by the governing laws, policies, or protocols in the locations where processing and storage occur and/or the locations from which system services emanate.

What to Check

• Verify SA-9(5) Processing, Storage, and Service Location is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SA-9(5)
• Verify enhancement builds upon base control SA-9

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-9(5) 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.
