Monitoring identity provider logs is crucial for identifying potential security threats, and Sigma rules offer a standardized way to define pattern detection rules in YAML format, enhancing the capability to search logs efficiently. The Grafana Labs Security Operations team has developed a GitHub Action that automates the validation of Sigma rules using a JSON Schema they created, replacing the outdated Rx Schema previously in use. This initiative was part of an internal project that integrated pySigma and pySigma-backend-loki, which translates Sigma rules into LogQL queries for more effective security monitoring. The JSON Schema is now available on the Schema Store and is used to validate each new commit in the Sigma repository. The GitHub Action, now available on the GitHub Marketplace, allows users to validate Sigma rules in both public and private repositories, accommodating custom JSON Schemas if needed. This collaborative project with the Sigma maintainers has resulted in the creation of the sigma-rules-validator project, which encourages community feedback and contributions to further enhance the tool's functionality.
