# IR-9(3) Post-spill Operations

> **Enhancement of:** IR-9

## High-Level Description

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

Corrective actions for systems contaminated due to information spillages may be time-consuming. Personnel may not have access to the contaminated systems while corrective actions are being taken, which may potentially affect their ability to conduct organizational business.

## What to Check

- [ ] Verify IR-9(3) Post-spill Operations is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for IR-9(3)
- [ ] Verify enhancement builds upon base control IR-9

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-9(3) 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

Implement the following procedures to ensure that organizational personnel impacted by information spills can continue to carry out assigned tasks while contaminated systems are undergoing corrective actions: [organization-defined].

### Implementation Guidance

Corrective actions for systems contaminated due to information spillages may be time-consuming. Personnel may not have access to the contaminated systems while corrective actions are being taken, which may potentially affect their ability to conduct organizational business.
