Sigma rules are a great way to identify suspicious activity and detect anomalies in log events. With the Sigma syntax, you can easily express detection logic for a wide range of logs, making it a powerful framework to use.

You can use Sigma to write rules for detecting threats across different log types, including proxy logs, Windows events, application logs, firewall logs, cloud events, Linux audit logs, and many more.

Corporate networks often consist of hundreds or thousands of devices that generate millions of lines of logs every minute. To sift through all this information efficiently and separate malicious activity from daily noise in an automated fashion, SOC and threat intel analysts can rely on Sigma rules.

This training covers the most critical components of Sigma rules, including log source and detection, Sigma taxonomy, and testing Sigma rules. It aims to prepare analysts who are new to Sigma to write their first rules.
