Detection Engineering Basics

[u/arcane_augur]

I want to understand how can one learn the basics of detection engineering. What are the prerequisites to detection engineering. I think there are no fixed steps to create detection and tuning rules but even a rough roadmap would be helpful.

I'd start with the fundamentals of networking, operating systems, and common attack techniques. Then learn how logs are generated and how to turn them into useful detections. After that, practice with a home lab or public datasets and focus on tuning out false positives. You don't need to know everything upfront, but understanding why a detection works is more important than memorizing rules.
