## SKILL.md

# Adverse Event Analysis (DE.AE) Adverse Event Analysis

## High-Level Description

**Function:** DETECT (DE)
**Framework:** NIST Cybersecurity Framework v2.0

Anomalies, indicators of compromise, and other potentially adverse events are analyzed to characterize the events and detect cybersecurity incidents

## What to Check

- [ ] Verify Adverse Event Analysis (DE.AE) Adverse Event Analysis outcome is achieved
- [ ] Review documentation and evidence for Adverse Event Analysis (DE.AE)
- [ ] Assess organizational maturity for DETECT function

## How to Test

### Step 1: Identify Current Profile

Determine the organization's current and target CSF profile tier for Adverse Event Analysis (DE.AE).

### Step 2: Assess Outcome Achievement

```
# Review organizational policies and procedures
# Check for evidence that Adverse Event Analysis (DE.AE) outcome is met
# Interview stakeholders responsible for DETECT
```

### Step 3: Map to Technical Controls

Identify which SP 800-53 controls implement this CSF outcome and verify their operating effectiveness.
