PT-3(1) Data Tagging

Enhancement of: PT-3

High-Level Description

Family: Personally Identifiable Information Processing and Transparency (PT) Framework: NIST SP 800-53 Rev 5

Data tags support the tracking of processing purposes by conveying the purposes along with the relevant elements of personally identifiable information throughout the system. By conveying the processing purposes in a data tag along with the personally identifiable information as the information transits a system, a system owner or operator can identify whether a change in processing would be compatible with the identified and documented purposes. Data tags may also support the use of automated tools.

What to Check

• Verify PT-3(1) Data Tagging is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PT-3(1)
• Verify enhancement builds upon base control PT-3

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PT-3(1) 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.
