Every incident response process must end with two critical questions: What went wrong? And how do we prevent it next time? In this final episode of Domain 4, we explore the structure and value of root cause analysis (RCA) and the metrics analysts use to evaluate incident response performance. You'll learn techniques for identifying the initial failure point, tracing cascading effects, and distinguishing symptoms from causes.

We’ll also dive into performance indicators like Mean Time to Detect (MTTD), Mean Time to Respond (MTTR), Mean Time to Remediate (MTTM), and alert volume tracking. These metrics provide feedback loops that help teams improve processes, justify investments, and meet service-level objectives. For CySA+ and beyond, this episode cements your understanding of how reflection and measurement transform reactive teams into proactive ones. Brought to you by BareMetalCyber.com
