# CM-8(1) Updates During Installation and Removal

> **Enhancement of:** CM-8

## High-Level Description

**Family:** Configuration Management (CM)
**Framework:** NIST SP 800-53 Rev 5

Organizations can improve the accuracy, completeness, and consistency of system component inventories if the inventories are updated as part of component installations or removals or during general system updates. If inventories are not updated at these key times, there is a greater likelihood that the information will not be appropriately captured and documented. System updates include hardware, software, and firmware components.

## What to Check

- [ ] Verify CM-8(1) Updates During Installation and Removal is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for CM-8(1)
- [ ] Verify enhancement builds upon base control CM-8

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CM-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.

## Tools

| Tool            | Purpose                       | Usage                                     |
| --------------- | ----------------------------- | ----------------------------------------- |
| cloud-audit-mcp | Check configuration baselines | `cloud_audit_config`                      |
| AWS CLI         | Review Config rules           | `aws configservice describe-config-rules` |

## Remediation Guide

### Control Statement

Update the inventory of system components as part of component installations, removals, and system updates.

### Implementation Guidance

Organizations can improve the accuracy, completeness, and consistency of system component inventories if the inventories are updated as part of component installations or removals or during general system updates. If inventories are not updated at these key times, there is a greater likelihood that the information will not be appropriately captured and documented. System updates include hardware, software, and firmware components.

## Risk Assessment

| Finding                                                         | Severity | Impact                              |
| --------------------------------------------------------------- | -------- | ----------------------------------- |
| CM-8(1) Updates During Installation and Removal not implemented | Medium   | Configuration Management            |
| CM-8(1) partially implemented                                   | Low      | Incomplete Configuration Management |
