# PM-5 System Inventory

## High-Level Description

**Family:** Program Management (PM)
**Framework:** NIST SP 800-53 Rev 5

[OMB A-130](#27847491-5ce1-4f6a-a1e4-9e483782f0ef) provides guidance on developing systems inventories and associated reporting requirements. System inventory refers to an organization-wide inventory of systems, not system components as described in [CM-8](#cm-8).

## What to Check

- [ ] Verify PM-5 System Inventory is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PM-5

## How to Test

### Step 1: Review Documentation

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

## Tools
