# SI-18(5) Notice of Correction or Deletion

> **Enhancement of:** SI-18

## High-Level Description

**Family:** System and Information Integrity (SI)
**Framework:** NIST SP 800-53 Rev 5

When personally identifiable information is corrected or deleted, organizations take steps to ensure that all authorized recipients of such information, and the individual with whom the information is associated or their designated representatives, are informed of the corrected or deleted information.

## What to Check

- [ ] Verify SI-18(5) Notice of Correction or Deletion is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SI-18(5)
- [ ] Verify enhancement builds upon base control SI-18

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-18(5) 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.
