About MISP
MISP (Malware Information Sharing Platform) is an open-source threat intelligence platform for gathering, sharing, storing, and correlating Indicators of Compromise (IOCs) of targeted attacks, threat intelligence, financial fraud information, vulnerability information, and counter-terrorism data. It provides a robust data model for structuring threat data, automatic correlation of attributes and indicators, flexible sharing groups for controlled distribution, and import/export in STIX, OpenIOC, and many other formats. MISP includes a built-in feed system for consuming external threat intelligence, a REST API for automation, and taxonomies and galaxies for consistent classification. It's used by CERTs, SOCs, threat intelligence teams, and law enforcement worldwide as their primary threat intelligence management platform.
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.
