IR-8(1)_breaches

IR-8(1) Breaches

Enhancement of: IR-8

High-Level Description

Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5

Organizations may be required by law, regulation, or policy to follow specific procedures relating to breaches, including notice to individuals, affected organizations, and oversight bodies; standards of harm; and mitigation or other specific requirements.

What to Check

• Verify IR-8(1) Breaches is documented in SSP
• Validate all 3 control requirements are implemented
• Confirm control is operating effectively
• Review evidence of continuous monitoring for IR-8(1)
• Verify enhancement builds upon base control IR-8

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IR-8(1) 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.
