About Sigma
Sigma is a generic and open signature format for SIEM systems, analogous to what YARA is for files and Snort is for network traffic. Sigma rules describe log events in a YAML-based format that is independent of any specific SIEM product. Using the sigma-cli converter (pySigma), rules can be translated into native query languages for Splunk (SPL), Elasticsearch (Lucene/KQL), Microsoft Sentinel, QRadar, CrowdStrike, Carbon Black, Grep, and over 30 other backends. The Sigma rule repository contains thousands of community-contributed detection rules covering MITRE ATT&CK techniques, common malware behaviors, lateral movement, persistence mechanisms, and suspicious system activity. Security teams use Sigma to write detection logic once and deploy it across their entire detection infrastructure, regardless of which SIEM products they use. The format is maintained by the SigmaHQ project and has become the de facto standard for shareable detection rules.
About Wazuh
Wazuh is a free, open-source security platform that provides unified XDR (Extended Detection and Response) and SIEM (Security Information and Event Management) capabilities. It consists of an agent deployed on endpoints and a central server that collects, analyzes, and correlates security data. Wazuh performs real-time log analysis, file integrity monitoring, rootkit detection, vulnerability assessment, configuration compliance checking (CIS, PCI DSS, HIPAA, NIST), and active response. It detects threats using rules that correlate events from multiple sources, including endpoint logs, cloud services (AWS, Azure, GCP), containers, and network devices. Wazuh integrates with Elasticsearch and OpenSearch for log storage and visualization, and includes a custom dashboard for security operations. Its open-source nature and comprehensive feature set make it a popular alternative to commercial SIEM solutions.
