# IR-8(1) Breaches

> **Enhancement of:** IR-8

## High-Level Description

**Family:** Incident Response (IR)
**Framework:** NIST SP 800-53 Rev 5

Organizations may be required by law, regulation, or policy to follow specific procedures relating to breaches, including notice to individuals, affected organizations, and oversight bodies; standards of harm; and mitigation or other specific requirements.

## What to Check

- [ ] Verify IR-8(1) Breaches is documented in SSP
- [ ] Validate all 3 control requirements are implemented
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for IR-8(1)
- [ ] Verify enhancement builds upon base control IR-8

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-8(1) 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.

## Remediation Guide

### Control Statement

Include the following in the Incident Response Plan for breaches involving personally identifiable information:
A process to determine if notice to individuals or other organizations, including oversight organizations, is needed;
An assessment process to determine the extent of the harm, embarrassment, inconvenience, or unfairness to affected individuals and any mechanisms to mitigate such harms; and
Identification of applicable privacy requirements.

### Implementation Guidance

Organizations may be required by law, regulation, or policy to follow specific procedures relating to breaches, including notice to individuals, affected organizations, and oversight bodies; standards of harm; and mitigation or other specific requirements.
