Frequently Asked Questions
What is detection engineering?
Detection engineering is designing, building, testing, and maintaining the rules and analytics that find malicious activity in logs and endpoint data.
What makes a detection high fidelity?
A high-fidelity detection catches real malicious behavior with few false positives. It is specific, uses reliable data, and is tested against both attack and normal activity.
How do you improve rule performance in a SIEM?
Filter early on indexed fields, limit time ranges, avoid expensive wildcards, and use summary data. This free advanced Codelivly room covers practical optimization techniques.
