Elastic Security, previously known as Elastic SIEM, is a comprehensive solution that includes SIEM, endpoint security, threat hunting, and cloud monitoring. The platform leverages the MITRE ATT&CK framework to enhance security teams' understanding of attacker tactics and improve their threat detection capabilities. Elastic Security 7.6 introduced 92 detection rules aligned with ATT&CK, allowing users to generate "signals" based on risk and severity scores for effective triage. The system operates by running detection rules every five minutes, which output a signal when specific criteria are met. For effective threat analysis, users can configure and utilize Sysmon data, a Windows-specific application that logs various system activities, to trigger these rules. The document emphasizes the importance of live data testing through Sysmon to ensure the accuracy and reliability of threat detection, while cautioning against running tests on production systems without proper authorization. Proper setup involves using Sysmon in conjunction with Elasticsearch and Winlogbeat to ship logs in an ECS-compatible format, ensuring that Elastic SIEM can process and analyze the data efficiently.
