# CM-8(7) Centralized Repository

> **Enhancement of:** CM-8

## High-Level Description

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

Organizations may implement centralized system component inventories that include components from all organizational systems. Centralized repositories of component inventories provide opportunities for efficiencies in accounting for organizational hardware, software, and firmware assets. Such repositories may also help organizations rapidly identify the location and responsible individuals of components that have been compromised, breached, or are otherwise in need of mitigation actions. Organizations ensure that the resulting centralized inventories include system-specific information required for proper component accountability.

## What to Check

- [ ] Verify CM-8(7) Centralized Repository is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for CM-8(7)
- [ ] 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(7) 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

Provide a centralized repository for the inventory of system components.

### Implementation Guidance

Organizations may implement centralized system component inventories that include components from all organizational systems. Centralized repositories of component inventories provide opportunities for efficiencies in accounting for organizational hardware, software, and firmware assets. Such repositories may also help organizations rapidly identify the location and responsible individuals of components that have been compromised, breached, or are otherwise in need of mitigation actions. Organizations ensure that the resulting centralized inventories include system-specific information required for proper component accountability.

| Finding                                        | Severity | Impact                              |
| ---------------------------------------------- | -------- | ----------------------------------- |
| CM-8(7) Centralized Repository not implemented | Medium   | Configuration Management            |
| CM-8(7) partially implemented                  | Low      | Incomplete Configuration Management |
