cyberstrikeus IR-5 Incident Monitoring
High-Level Description
Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5
Documenting incidents includes maintaining records about each incident, the status of the incident, and other pertinent information necessary for forensics as well as evaluating incident details, trends, and handling. Incident information can be obtained from a variety of sources, including network monitoring, incident reports, incident response teams, user complaints, supply chain partners, audit monitoring, physical access monitoring, and user and administrator reports. IR-4 provides information on the types of incidents that are appropriate for monitoring.
What to Check
- Verify IR-5 Incident Monitoring is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for IR-5
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IR-5 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.
