# SR-8 Notification Agreements

## High-Level Description

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

The establishment of agreements and procedures facilitates communications among supply chain entities. Early notification of compromises and potential compromises in the supply chain that can potentially adversely affect or have adversely affected organizational systems or system components is essential for organizations to effectively respond to such incidents. The results of assessments or audits may include open-source information that contributed to a decision or result and could be used to help the supply chain entity resolve a concern or improve its processes.

## What to Check

- [ ] Verify SR-8 Notification Agreements is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SR-8

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SR-8 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 |
| ------------- | --------------------------------- | ----- |
| Manual Review | Documentation and interview-based | N/A   |

## Remediation Guide

### Control Statement

Establish agreements and procedures with entities involved in the supply chain for the system, system component, or system service for the [organization-defined].

### Implementation Guidance

The establishment of agreements and procedures facilitates communications among supply chain entities. Early notification of compromises and potential compromises in the supply chain that can potentially adversely affect or have adversely affected organizational systems or system components is essential for organizations to effectively respond to such incidents. The results of assessments or audits may include open-source information that contributed to a decision or result and could be used to help the supply chain entity resolve a concern or improve its processes.

| -------------------------------------------- | -------- | --------------------------------------- |
| SR-8 Notification Agreements not implemented | Medium   | Supply Chain Risk Management            |
| SR-8 partially implemented                   | Low      | Incomplete Supply Chain Risk Management |
