# MA-6(2) Predictive Maintenance

> **Enhancement of:** MA-6

## High-Level Description

**Family:** Maintenance (MA)
**Framework:** NIST SP 800-53 Rev 5

Predictive maintenance evaluates the condition of equipment by performing periodic or continuous (online) equipment condition monitoring. The goal of predictive maintenance is to perform maintenance at a scheduled time when the maintenance activity is most cost-effective and before the equipment loses performance within a threshold. The predictive component of predictive maintenance stems from the objective of predicting the future trend of the equipment's condition. The predictive maintenance approach employs principles of statistical process control to determine at what point in the future maintenance activities will be appropriate. Most predictive maintenance inspections are performed while equipment is in service, thus minimizing disruption of normal system operations. Predictive maintenance can result in substantial cost savings and higher system reliability.

## What to Check

- [ ] Verify MA-6(2) Predictive Maintenance is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for MA-6(2)
- [ ] Verify enhancement builds upon base control MA-6

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for MA-6(2) 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.
