# AT-2(2) Insider Threat

> **Enhancement of:** AT-2

## High-Level Description

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

Potential indicators and possible precursors of insider threat can include behaviors such as inordinate, long-term job dissatisfaction; attempts to gain access to information not required for job performance; unexplained access to financial resources; bullying or harassment of fellow employees; workplace violence; and other serious violations of policies, procedures, directives, regulations, rules, or practices. Literacy training includes how to communicate the concerns of employees and management regarding potential indicators of insider threat through channels established by the organization and in accordance with established policies and procedures. Organizations may consider tailoring insider threat awareness topics to the role. For example, training for managers may be focused on changes in the behavior of team members, while training for employees may be focused on more general observations.

## What to Check

- [ ] Verify AT-2(2) Insider Threat is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for AT-2(2)
- [ ] Verify enhancement builds upon base control AT-2

## How to Test

### Step 1: Review Documentation

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