# PS-4(2) Automated Actions

> **Enhancement of:** PS-4

## High-Level Description

**Family:** Personnel Security (PS)
**Framework:** NIST SP 800-53 Rev 5

In organizations with many employees, not all personnel who need to know about termination actions receive the appropriate notifications, or if such notifications are received, they may not occur in a timely manner. Automated mechanisms can be used to send automatic alerts or notifications to organizational personnel or roles when individuals are terminated. Such automatic alerts or notifications can be conveyed in a variety of ways, including via telephone, electronic mail, text message, or websites. Automated mechanisms can also be employed to quickly and thoroughly disable access to system resources after an employee is terminated.

## What to Check

- [ ] Verify PS-4(2) Automated Actions is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PS-4(2)
- [ ] Verify enhancement builds upon base control PS-4

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PS-4(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.
