SI-18(2) Data Tags

Enhancement of: SI-18

High-Level Description

Family: System and Information Integrity (SI) Framework: NIST SP 800-53 Rev 5

Data tagging personally identifiable information includes tags that note processing permissions, authority to process, de-identification, impact level, information life cycle stage, and retention or last updated dates. Employing data tags for personally identifiable information can support the use of automation tools to correct or delete relevant personally identifiable information.

What to Check

• Verify SI-18(2) Data Tags is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-18(2)
• Verify enhancement builds upon base control SI-18

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-18(2) 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.
