Splunk Enterprise Reviews & Ratings 2023

Splunk Enterprise is a brilliant tool that we use in the University of Colorado, Denver to analyze logs obtained from various sources. Our team is responsible for maintaining the security of our campus and the University of Colorado, Anschutz medical campus.

The log sources are typically firewall logs, email logs, logs from the Intrusion detection system (IDS), logs of different services running on the google cloud, etc. It offers a very easy interface and a query language. We can build our own alarm rule and UI within it for visualization. The rules will run at a time defined by the user and will send metrics to the email. It helped in automating blacklisting as now we can get the most troublesome IP addresses and block them in a minute. It also helped us in tracing a list of most vulnerable on the campus. The most powerful feature is the correlation of log sources. Correlation of log sources is a very taxing process for any software. Splunk handles this gracefully. By correlating firewall traffic, wireless and IDS traffic we once spotted a machine that had a trojan in it and was trying to spread itself laterally through open SMB ports.
