# AT-3(3) Practical Exercises

> **Enhancement of:** AT-3

## High-Level Description

**Family:** Awareness and Training (AT)
**Framework:** NIST SP 800-53 Rev 5

Practical exercises for security include training for software developers that addresses simulated attacks that exploit common software vulnerabilities or spear or whale phishing attacks targeted at senior leaders or executives. Practical exercises for privacy include modules with quizzes on identifying and processing personally identifiable information in various scenarios or scenarios on conducting privacy impact assessments.

## What to Check

- [ ] Verify AT-3(3) Practical Exercises is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for AT-3(3)
- [ ] Verify enhancement builds upon base control AT-3

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for AT-3(3) 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

Provide practical exercises in security and privacy training that reinforce training objectives.

### Implementation Guidance

Practical exercises for security include training for software developers that addresses simulated attacks that exploit common software vulnerabilities or spear or whale phishing attacks targeted at senior leaders or executives. Practical exercises for privacy include modules with quizzes on identifying and processing personally identifiable information in various scenarios or scenarios on conducting privacy impact assessments.

## Risk Assessment

| Finding                                     | Severity | Impact                            |
| ------------------------------------------- | -------- | --------------------------------- |
| AT-3(3) Practical Exercises not implemented | Medium   | Awareness and Training            |
| AT-3(3) partially implemented               | Low      | Incomplete Awareness and Training |
