This repository contains the configuration and support files for the SANS FOR572 SOF-ELK® VM Appliance. SOF-ELK® is a “big data analytics” platform focused on the typical needs of computer forensic investigators/analysts and information security operations personnel. The platform is a customized build of the open source ELK stack, consisting of the Elasticsearch storage and search engine, Logstash ingest and enrichment system, and the Kibana dashboard frontend. With a significant amount of customization and ongoing development, SOF-ELK® users can avoid the typically long and involved setup process the ELK stack requires. Instead, they can simply download the pre-built and ready-to-use SOF-ELK® virtual appliance that consumes various source data types (numerous log types as well as NetFlow), parsing out the most critical data and visualizing it on several stock dashboards. Advanced users can build visualizations the suit their own investigative or operational requirements, optionally contributing those back to the primary code repository.
