Building an Open SIEM From Scratch
I have used Elastic Stack few times whether in a Threat Hunting Lab or Detection & Behavior analysis contexts. This series of blogs is about sharing what I learned in the process.
Building a SIEM based on open-sourced solutions can be particularly challenging but also much more fun. In this article series I will try to share how can we overcome some of the basic challenges that we may face during building such toolsets like:
- Data normalization.
- Event collection and processing.
- Alerting : Time-based vs Event-Centric correlation
- Visualizations and Dashboarding
- SIEM metrics and reporting
I will be using the following tools:
- Elastic Stack: Elasticsearch, Kibana, Logstash, and Beats for collecting, processing, storing, and searching data.
- OpenDistro for Elasticsearch plugins for Alerting and Security.
- ElastAlert for additional alerting features
