📋 Incident Response Cheat Sheet

Quick reference for the incident response lifecycle tested on the CyberOps exam.

Why This Cheat Sheet Matters for CYBEROPS

This cheat sheet covers the most important CyberOps Incident Handling concepts tested on the CYBEROPS (CyberOps Associate) certification exam. It contains 2 sections with 10 key points that you should memorize before exam day. Learn the incident response lifecycle (preparation, detection, containment, eradication, recovery, lessons learned), escalation procedures, evidence handling, and post-incident activities. Use this as a quick-reference guide during your final review sessions.

NIST IR Phases

  • 1. Preparation: policies, tools, training, communication plans.
  • 2. Detection & Analysis: identify IOCs, triage alerts, determine scope.
  • 3. Containment: short-term (isolate host) + long-term (patch, segment).
  • 4. Eradication: remove malware, close vulnerabilities.
  • 5. Recovery: restore systems, monitor for re-infection.
  • 6. Post-Incident: lessons learned, update playbooks.

Evidence Handling

  • Maintain chain of custody: document who handled evidence, when, how.
  • Create forensic images — never work on the original.
  • Use hash values (SHA-256) to verify evidence integrity.
  • Volatile evidence first: memory → network connections → running processes → disk.

Cisco Command Quick Reference

Cisco IOS commands follow a hierarchical structure: User EXEC mode (>), Privileged EXEC mode (#), Global Configuration mode (config)#, and Interface Configuration mode (config-if)#. Master the transitions between these modes and the key "show" commands for each technology area — they are heavily tested on every Cisco exam.
