# CM-2(6) Development and Test Environments

> **Enhancement of:** CM-2

## High-Level Description

**Family:** Configuration Management (CM)
**Framework:** NIST SP 800-53 Rev 5

Establishing separate baseline configurations for development, testing, and operational environments protects systems from unplanned or unexpected events related to development and testing activities. Separate baseline configurations allow organizations to apply the configuration management that is most appropriate for each type of configuration. For example, the management of operational configurations typically emphasizes the need for stability, while the management of development or test configurations requires greater flexibility. Configurations in the test environment mirror configurations in the operational environment to the extent practicable so that the results of the testing are representative of the proposed changes to the operational systems. Separate baseline configurations do not necessarily require separate physical environments.

## What to Check

- [ ] Verify CM-2(6) Development and Test Environments is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for CM-2(6)
- [ ] Verify enhancement builds upon base control CM-2

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CM-2(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                                     |
| --------------- | ----------------------------- | ----------------------------------------- |
| cloud-audit-mcp | Check configuration baselines | `cloud_audit_config`                      |
| AWS CLI         | Review Config rules           | `aws configservice describe-config-rules` |

## Remediation Guide

### Control Statement

Maintain a baseline configuration for system development and test environments that is managed separately from the operational baseline configuration.

### Implementation Guidance

Establishing separate baseline configurations for development, testing, and operational environments protects systems from unplanned or unexpected events related to development and testing activities. Separate baseline configurations allow organizations to apply the configuration management that is most appropriate for each type of configuration. For example, the management of operational configurations typically emphasizes the need for stability, while the management of development or test configurations requires greater flexibility. Configurations in the test environment mirror configurations in the operational environment to the extent practicable so that the results of the testing are representative of the proposed changes to the operational systems. Separate baseline configurations do not necessarily require separate physical environments.

## Risk Assessment

| Finding                                                   | Severity | Impact                              |
| --------------------------------------------------------- | -------- | ----------------------------------- |
| CM-2(6) Development and Test Environments not implemented | Medium   | Configuration Management            |
| CM-2(6) partially implemented                             | Low      | Incomplete Configuration Management |
