# PT-2(1) Data Tagging

> **Enhancement of:** PT-2

## High-Level Description

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

Data tags support the tracking and enforcement of authorized processing by conveying the types of processing that are authorized along with the relevant elements of personally identifiable information throughout the system. Data tags may also support the use of automated tools.

## What to Check

- [ ] Verify PT-2(1) Data Tagging is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PT-2(1)
- [ ] Verify enhancement builds upon base control PT-2

## How to Test

### Step 1: Review Documentation

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

## Tools

| Tool          | Purpose                           | Usage |
| ------------- | --------------------------------- | ----- |
| Manual Review | Documentation and interview-based | N/A   |

## Remediation Guide

### Control Statement

Attach data tags containing [organization-defined] to [organization-defined].

### Implementation Guidance

Data tags support the tracking and enforcement of authorized processing by conveying the types of processing that are authorized along with the relevant elements of personally identifiable information throughout the system. Data tags may also support the use of automated tools.

## Risk Assessment

| Finding                              | Severity | Impact                                                                     |
| ------------------------------------ | -------- | -------------------------------------------------------------------------- |
| PT-2(1) Data Tagging not implemented | Medium   | Personally Identifiable Information Processing and Transparency            |
| PT-2(1) partially implemented        | Low      | Incomplete Personally Identifiable Information Processing and Transparency |

## CWE Categories
