We'll soon set a date for its deprecation. WARNING: Do not provide conversion backends for this tool anymore. Merges multiple YAML documents of a Sigma rule collection into simple Sigma rules.

Use the Rule Creation Guide in our Wiki for a clear guidance on how to populate the various field in Sigma rules. Getting Started Rule Creationįlorian wrote a short rule creation tutorial that can help you getting started. The specifications can be found in the Wiki. Sigma - Make Security Monitoring Great Again Specification See the first slide deck that I prepared for a private conference in mid January 2017. Sigma is meant to be an open standard in which such detection mechanisms can be defined, shared and collected in order to improve the detection capabilities for everyone. Others provide excellent analyses, include IOCs and YARA rules to detect the malicious files and network connections, but have no way to describe a specific or generic detection method in log events. Some of their searches and correlations are great and very useful but they lack a standardized format in which they can share their work with others. People start working on their own, processing numerous white papers, blog posts and log analysis guidelines, extracting the necessary information and build their own searches and dashboard. Today, everyone collects log data for analysis.

Provide Sigma signatures for malicious behaviour in your own application.

Share the signature in threat intel communities - e.g.

Share the signature in the appendix of your analysis along with IOCs and YARA rules.

Write your SIEM searches in Sigma to avoid a vendor lock-in.

Describe your detection method in Sigma to make it shareable.

The main purpose of this project is to provide a structured form in which researchers or analysts can describe their once developed detection methods and make them shareable with others. The rule format is very flexible, easy to write and applicable to any type of log file. Sigma is a generic and open signature format that allows you to describe relevant log events in a straightforward manner. Generic Signature Format for SIEM Systems What is Sigma
