Splunk is a SIEM (Security Information and Event Management) solution that collects logs from various sources (server, network devices, applications, etc.), stores (indexes) the collected logs, and provides search, research, analysis and correlation on the stored logs. With its simple logic, Splunk works with the forwarder, indexer and master structure. Splunk can be used for free up to a certain 500 MB value.
