IR Preparation and Playbooks and Detection and Forensics | Six Minutes: CompTIA Security+, Part 44

Six Minutes: CompTIA Security+, Part 44: IR Preparation and Playbooks and Detection and Forensics: Security Operations: roles, playbooks, tabletops, and simulations; then Detection and Forensics Incident response preparation means assigning roles with owners and backups, and writing playbooks that state the trigger, steps, owners, and escalation points. Tabletop exercises test the plan safely while simulations test hands-on skills, and both must be repeated after staff changes and real incidents. Then: How incidents are identified through alerts, internal and external threat intelligence, and threat hunting, and how digital forensics preserves evidence with chain of custody and e-discovery. A first-responder walkthrough shows the preserve, image, hash, log, analyze order.

A warehouse company's playbook says only 'restore from backup' for ransomware. List the four elements a complete playbook should state, and name the exercise type that tests the plan without touching systems. Answer: trigger, ordered steps, role owners, escalation point; a tabletop exercise. 2. At Beacon Ridge Utilities, the incident lead left the company and the backup restore was never tested. Which two preparation failures does this show, and what fixes them? Answer: no backup role owner and no testing; assign a backup owner and run simulations/restore tests on a schedule. 3. A vendor bulletin warns that a flaw is being exploited in the wild. What kind of detection source is this? Answer: an external advisory. 4. You image a suspect drive and the copy's hash differs from the original's. What do you do? Answer: do not analyze the copy; re-image the drive and hash again.
