# SC-36(2) Synchronization

> **Enhancement of:** SC-36

## High-Level Description

**Family:** System and Communications Protection (SC)
**Framework:** NIST SP 800-53 Rev 5

[SC-36](#sc-36) and [CP-9(6)](#cp-9.6) require the duplication of systems or system components in distributed locations. The synchronization of duplicated and redundant services and data helps to ensure that information contained in the distributed locations can be used in the mission or business functions of organizations, as needed.

## What to Check

- [ ] Verify SC-36(2) Synchronization is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SC-36(2)
- [ ] Verify enhancement builds upon base control SC-36

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-36(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.

## Tools

| Tool            | Purpose                               | Usage                                |
| --------------- | ------------------------------------- | ------------------------------------ |
| cloud-audit-mcp | Check encryption and network controls | `cloud_audit_encryption`             |
| nmap            | Network scanning                      | `nmap -sV --script ssl-enum-ciphers` |

## Remediation Guide

### Control Statement

Synchronize the following duplicate systems or system components: [organization-defined].

### Implementation Guidance

[SC-36](#sc-36) and [CP-9(6)](#cp-9.6) require the duplication of systems or system components in distributed locations. The synchronization of duplicated and redundant services and data helps to ensure that information contained in the distributed locations can be used in the mission or business functions of organizations, as needed.

## Risk Assessment

| Finding                                  | Severity | Impact                                          |
| ---------------------------------------- | -------- | ----------------------------------------------- |
| SC-36(2) Synchronization not implemented | High     | System and Communications Protection            |
| SC-36(2) partially implemented           | Medium   | Incomplete System and Communications Protection |

## CWE Categories

| CWE ID  | Title                                |
