SA-8(33)_minimization

SA-8(33) Minimization

Enhancement of: SA-8

High-Level Description

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

The principle of minimization states that organizations should only process personally identifiable information that is directly relevant and necessary to accomplish an authorized purpose and should only maintain personally identifiable information for as long as is necessary to accomplish the purpose. Organizations have processes in place, consistent with applicable laws and policies, to implement the principle of minimization.

What to Check

• Verify SA-8(33) Minimization is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SA-8(33)
• Verify enhancement builds upon base control SA-8

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-8(33) 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.
