This blog series provides a comprehensive guide on integrating the Elastic Stack with ArcSight SIEM to enhance security analytics capabilities, detailing the process of sending Common Event Format data from ArcSight to Elasticsearch using Logstash and Kibana, and leveraging X-Pack for added functionalities. The series outlines steps for setting up the Elastic Stack, including the installation of Elasticsearch, Kibana, and Logstash with X-Pack, and configuring ArcSight Smart Connectors to send data to Logstash. It also emphasizes the importance of exploring security data through Kibana dashboards and visualizations, and discusses the role of X-Pack alerting in monitoring security events. Further, the series plans to extend into scaling the architecture, setting up alerts for common security threats, and employing machine learning for anomaly detection, with additional insights on using ArcSight alongside Kafka and other security analytics tools.
