# SR-4(2) Track and Trace

> **Enhancement of:** SR-4

## High-Level Description

**Family:** Supply Chain Risk Management (SR)
**Framework:** NIST SP 800-53 Rev 5

Tracking the unique identification of systems and system components during development and transport activities provides a foundational identity structure for the establishment and maintenance of provenance. For example, system components may be labeled using serial numbers or tagged using radio-frequency identification tags. Labels and tags can help provide better visibility into the provenance of a system or system component. A system or system component may have more than one unique identifier. Identification methods are sufficient to support a forensic investigation after a supply chain compromise or event.

## What to Check

- [ ] Verify SR-4(2) Track and Trace is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SR-4(2)
- [ ] Verify enhancement builds upon base control SR-4

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SR-4(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.

## Remediation Guide

### Control Statement

Establish and maintain unique identification of the following systems and critical system components for tracking through the supply chain: [organization-defined].

### Implementation Guidance

Tracking the unique identification of systems and system components during development and transport activities provides a foundational identity structure for the establishment and maintenance of provenance. For example, system components may be labeled using serial numbers or tagged using radio-frequency identification tags. Labels and tags can help provide better visibility into the provenance of a system or system component. A system or system component may have more than one unique identifier.
