From my short time of searching the internet I never found a guide to setting up a logging system for Windows from start to finsh. An effective logging system has an agentcollector, a log aggregator, a data visualizer, and a good alerting mechnism. The following sytem I have setup has WazuhOSSEC fork for log collection, Wazuh Management for a log aggregator, the ELK stack for data retention and vizualiztion, and elastalert for e mail alerting. In this guide I will walk you through on how to setup an effective logging system for all operating systems but mainly Windows for free. Additionally, we will be discussing the type of things that should be logged depending on your enviornment. Optional gcc 4. 6. Ubuntu packages. We provide several PPAs to add to your Ubuntu installation For stable releases add the Darktable Release PPA.

Wazuh HIDS Performs log analysis, file integrity checking, policy monitoring, rootkitsmalware detection and real time alerting. The alerts are written in an extended JSON format, and stored locally on the box running as the OSSEC manager. Logstash Is a data pipeline used for processing logs and other event data from a variety of systems. Logstash will read and process OSSEC JSON files, adding IP Geolocation information and modeling data before sending it to the Elasticsearch Cluster. Elasticsearch Is the search engine used to index and store our OSSEC alerts. It can be deployed as a cluster, with multiple nodes, for better performance and data replication. Kibana Kibana is a WEB framework used to explore all elasticsearch indexes. We will use it to analyze OSSEC alerts and to create custom dashboards for different use cases, including compliance regulations like PCI DSS or benchmarks like CIS.
