# PT-6(2) Exemption Rules

> **Enhancement of:** PT-6

## High-Level Description

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

The [PRIVACT](#18e71fec-c6fd-475a-925a-5d8495cf8455) includes two sets of provisions that allow federal agencies to claim exemptions from certain requirements in the statute. In certain circumstances, these provisions allow agencies to promulgate regulations to exempt a system of records from select provisions of the [PRIVACT](#18e71fec-c6fd-475a-925a-5d8495cf8455) . At a minimum, organizations’ [PRIVACT](#18e71fec-c6fd-475a-925a-5d8495cf8455) exemption regulations include the specific name(s) of any system(s) of records that will be exempt, the specific provisions of the [PRIVACT](#18e71fec-c6fd-475a-925a-5d8495cf8455) from which the system(s) of records is to be exempted, the reasons for the exemption, and an explanation for why the exemption is both necessary and appropriate.

## What to Check

- [ ] Verify PT-6(2) Exemption Rules is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PT-6(2)
- [ ] Verify enhancement builds upon base control PT-6

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PT-6(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.
