# PE-6(2) Automated Intrusion Recognition and Responses

> **Enhancement of:** PE-6

## High-Level Description

**Family:** Physical and Environmental Protection (PE)
**Framework:** NIST SP 800-53 Rev 5

Response actions can include notifying selected organizational personnel or law enforcement personnel. Automated mechanisms implemented to initiate response actions include system alert notifications, email and text messages, and activating door locking mechanisms. Physical access monitoring can be coordinated with intrusion detection systems and system monitoring capabilities to provide integrated threat coverage for the organization.

## What to Check

- [ ] Verify PE-6(2) Automated Intrusion Recognition and Responses is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PE-6(2)
- [ ] Verify enhancement builds upon base control PE-6

## How to Test

### Step 1: Review Documentation

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

## Tools

| Tool          | Purpose                           | Usage |

## Remediation Guide

### Control Statement

Recognize [organization-defined] and initiate [organization-defined] using [organization-defined].

### Implementation Guidance

Response actions can include notifying selected organizational personnel or law enforcement personnel. Automated mechanisms implemented to initiate response actions include system alert notifications, email and text messages, and activating door locking mechanisms. Physical access monitoring can be coordinated with intrusion detection systems and system monitoring capabilities to provide integrated threat coverage for the organization.
