How To Install And Integrate Splunk Universal Forwarder In Linux
Splunk is a SIEM solution that allows us to collect, analyze, and correlate logs in a centralized server in real-time. This video will cover installing Splunk on Linux and configuring different log sources from Linux into Splunk.
The steps are as follow:
- Install and integrate Universal Forwarder
- Collecting Logs from important logs sources/files like syslog, auth.log, audited, etc
Splunk has two primary types of forwarders that can be used in different use cases. They are explained below:
Heavy Forwarders:
Heavy forwarders are used when we need to apply a filter, analyze or make changes to the logs at the source before forwarding it to the destination. In this video, we will be installing and configuring Universal forwarders.
Universal Forwarders:
It is a lightweight agent that gets installed on the target host, and its main purpose is to get the logs and send them to the Splunk instance or another forwarder without applying any filters or indexing.
Universal forwarders can be downloaded from the official Splunk website. It supports various OS.
Linux Log Sources:
Linux stores all its important logs into the /var/log file, as shown below. In our case, we will ingest syslog into Splunk. All other logs can be ingested using the same method.
