# SA-17(6) Structure for Testing

> **Enhancement of:** SA-17

## High-Level Description

**Family:** System and Services Acquisition (SA)
**Framework:** NIST SP 800-53 Rev 5

Applying the security design principles in [SP 800-160-1](#e3cc0520-a366-4fc9-abc2-5272db7e3564) promotes complete, consistent, and comprehensive testing and evaluation of systems, system components, and services. The thoroughness of such testing contributes to the evidence produced to generate an effective assurance case or argument as to the trustworthiness of the system, system component, or service.

## What to Check

- [ ] Verify SA-17(6) Structure for Testing is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SA-17(6)
- [ ] Verify enhancement builds upon base control SA-17

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-17(6) 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

Require the developer of the system, system component, or system service to structure security-relevant hardware, software, and firmware to facilitate testing.

### Implementation Guidance

Applying the security design principles in [SP 800-160-1](#e3cc0520-a366-4fc9-abc2-5272db7e3564) promotes complete, consistent, and comprehensive testing and evaluation of systems, system components, and services. The thoroughness of such testing contributes to the evidence produced to generate an effective assurance case or argument as to the trustworthiness of the system, system component, or service.

| ---------------------------------------------- | -------- | ------------------------------------------ |
| SA-17(6) Structure for Testing not implemented | Medium   | System and Services Acquisition            |
| SA-17(6) partially implemented                 | Low      | Incomplete System and Services Acquisition |

## CWE Categories
