# SA-10(4) Trusted Generation

> **Enhancement of:** SA-10

## High-Level Description

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

The trusted generation of descriptions, source code, and object code addresses authorized changes to hardware, software, and firmware components between versions during development. The focus is on the efficacy of the configuration management process by the developer to ensure that newly generated versions of security-relevant hardware descriptions, source code, and object code continue to enforce the security policy for the system, system component, or system service. In contrast, [SA-10(1)](#sa-10.1) and [SA-10(3)](#sa-10.3) allow organizations to detect unauthorized changes to hardware, software, and firmware components using tools, techniques, or mechanisms provided by developers.

## What to Check

- [ ] Verify SA-10(4) Trusted Generation is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SA-10(4)
- [ ] Verify enhancement builds upon base control SA-10

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-10(4) 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 employ tools for comparing newly generated versions of security-relevant hardware descriptions, source code, and object code with previous versions.

### Implementation Guidance

The trusted generation of descriptions, source code, and object code addresses authorized changes to hardware, software, and firmware components between versions during development. The focus is on the efficacy of the configuration management process by the developer to ensure that newly generated versions of security-relevant hardware descriptions, source code, and object code continue to enforce the security policy for the system, system component, or system service. In contrast, [SA-10(1)](#sa-10.1) and [SA-10(3)](#sa-10.3) allow organizations to detect unauthorized changes to hardware, software, and firmware components using tools, techniques, or mechanisms provided by developers.

| Finding                                     | Severity | Impact                                     |
| ------------------------------------------- | -------- | ------------------------------------------ |
| SA-10(4) Trusted Generation not implemented | Medium   | System and Services Acquisition            |
| SA-10(4) partially implemented              | Low      | Incomplete System and Services Acquisition |
