# RS.AN-05 RS.AN-05

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

## High-Level Description

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

Processes are established to receive, analyze and respond to vulnerabilities disclosed to the organization from internal and external sources (e.g. internal testing, security bulletins, or security researchers)

## What to Check

- [ ] Verify RS.AN-05 RS.AN-05 outcome is achieved
- [ ] Review documentation and evidence for RS.AN-05
- [ ] Assess organizational maturity for RESPOND function
- [ ] Map to SP 800-53 controls that satisfy RS.AN-05

## How to Test

### Step 1: Identify Current Profile

Determine the organization's current and target CSF profile tier for RS.AN-05.

### Step 2: Assess Outcome Achievement

```
# Review organizational policies and procedures
# Check for evidence that RS.AN-05 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.
