Detection engineering with Sigma

When it applies

You need a detection that survives a SIEM change: express the logic once in Sigma (a generic YAML rule format), then compile to Splunk/Elastic/Sentinel/etc. Pairs with offensive skills — every technique you learn to run, you can learn to catch.

Why it works

Sigma abstracts log-source + condition from backend query syntax, so one rule ports across SIEMs and reviews cleanly. Mapping to ATT&CK gives coverage you can measure and gaps you can see.
