# SI-4(17) Integrated Situational Awareness

> **Enhancement of:** SI-4

## High-Level Description

**Family:** System and Information Integrity (SI)
**Framework:** NIST SP 800-53 Rev 5

Correlating monitoring information from a more diverse set of information sources helps to achieve integrated situational awareness. Integrated situational awareness from a combination of physical, cyber, and supply chain monitoring activities enhances the capability of organizations to more quickly detect sophisticated attacks and investigate the methods and techniques employed to carry out such attacks. In contrast to [SI-4(16)](#si-4.16) , which correlates the various cyber monitoring information, integrated situational awareness is intended to correlate monitoring beyond the cyber domain. Correlation of monitoring information from multiple activities may help reveal attacks on organizations that are operating across multiple attack vectors.

## What to Check

- [ ] Verify SI-4(17) Integrated Situational Awareness is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SI-4(17)
- [ ] Verify enhancement builds upon base control SI-4

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-4(17) 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 integrity monitoring | `cloud_audit_monitoring`       |
| AWS CLI         | Review GuardDuty/Inspector | `aws guardduty list-detectors` |

## Remediation Guide

### Control Statement

Correlate information from monitoring physical, cyber, and supply chain activities to achieve integrated, organization-wide situational awareness.

### Implementation Guidance

Correlating monitoring information from a more diverse set of information sources helps to achieve integrated situational awareness. Integrated situational awareness from a combination of physical, cyber, and supply chain monitoring activities enhances the capability of organizations to more quickly detect sophisticated attacks and investigate the methods and techniques employed to carry out such attacks. In contrast to [SI-4(16)](#si-4.16) , which correlates the various cyber monitoring information, integrated situational awareness is intended to correlate monitoring beyond the cyber domain. Correlation of monitoring information from multiple activities may help reveal attacks on organizations that are operating across multiple attack vectors.
