ROOT CAUSE ANALYSIS
Root cause analysis: find out why it happened
We trace an incident back to its source and show how to stop it happening again.
What is a security root cause analysis?
A security root cause analysis (RCA) is a structured investigation after an incident to find how it started, why existing controls did not stop it and what must change. It uses logs and evidence to build a timeline, identifies technical and process gaps, and gives a fix plan to prevent repeats.
Fixing symptoms invites the next incident.
An RCA finds the real cause, so the same gap is not used again.
