SI-7(7) Integration of Detection and Response

Enhancement of: SI-7

High-Level Description

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

Integrating detection and response helps to ensure that detected events are tracked, monitored, corrected, and available for historical purposes. Maintaining historical records is important for being able to identify and discern adversary actions over an extended time period and for possible legal actions. Security-relevant changes include unauthorized changes to established configuration settings or the unauthorized elevation of system privileges.

What to Check

• Verify SI-7(7) Integration of Detection and Response is documented in SSP
• Confirm control is operating effectively
• Review evidence of continuous monitoring for SI-7(7)
• Verify enhancement builds upon base control SI-7

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SI-7(7) 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.
