Episode 41 — Eliminate Single Points of Failure Before They Become Incident Headlines
This episode explains how single points of failure show up in real architectures and why ISSEP questions often test whether you can spot them early, before they turn into outages, data loss, or uncontrolled privilege escalation. We define a single point of failure as any component, path, or dependency whose loss causes mission-impacting failure, then expand the idea to include “security SPOFs,” like one identity provider, one logging pipeline, one key store, or one administrator workflow that, if compromised, collapses defenses. You’ll learn practical ways to identify SPOFs by mapping dependencies, failure modes, and operational procedures, and by asking what happens during partial failures like network partition, degraded DNS, or an unavailable cloud control plane. We also cover best practices for designing redundancy and failover that are tested and observable, plus troubleshooting patterns where redundancy exists but does not work because of shared configuration, shared credentials, or common-mode dependencies. By the end, you should be able to explain and defend design changes that reduce risk while preserving performance, cost, and maintainability.
