# RS.AN-01 RS.AN-01

> **Subcategory of:** Incident Analysis (RS.AN)

## High-Level Description

**Function:** RESPOND (RS)
**Framework:** NIST Cybersecurity Framework v2.0

Notifications from detection systems are investigated

## What to Check

- [ ] Verify RS.AN-01 RS.AN-01 outcome is achieved
- [ ] Review documentation and evidence for RS.AN-01
- [ ] Assess organizational maturity for RESPOND function
- [ ] Map to SP 800-53 controls that satisfy RS.AN-01

## How to Test

### Step 1: Identify Current Profile

Determine the organization's current and target CSF profile tier for RS.AN-01.

### Step 2: Assess Outcome Achievement

```
# Review organizational policies and procedures
# Check for evidence that RS.AN-01 outcome is met
# Interview stakeholders responsible for RESPOND
```

### Step 3: Map to Technical Controls

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