Episode 12 — Protect Availability: BC/DR Testing, Connected Backups, Disconnected Backups, Recovery
This episode focuses on availability as a security property with measurable engineering requirements, not just a slogan, and shows how SecurityX questions commonly test your ability to select recovery strategies that match business impact and threat reality. You’ll clarify the roles of business continuity versus disaster recovery, then connect them to recovery objectives, dependency mapping, and runbook quality so you can recognize when a plan is technically sound but operationally unusable. We’ll compare connected backups and disconnected backups through the lens of ransomware and destructive incidents, including how backup immutability, credential separation, and recovery network design reduce blast radius. You’ll learn why testing matters more than documentation, how to structure tabletop exercises versus technical failover drills, and what successful testing evidence looks like when auditors or executives ask whether recovery claims are credible. We’ll also troubleshoot frequent failure modes such as backups that cannot be restored, missing encryption keys, untested identity dependencies, and DR environments that silently age out of compatibility. The goal is to answer exam scenarios with a clear recovery decision framework that balances speed, cost, and survivability.
