InfoSec App for Splunk
Overview
Details
InfoSec app is designed to address the most common security use cases, including continuous monitoring and security investigations. InfoSec app also includes a number of advanced threat detection use cases.
All of the components of InfoSec app can be easily expanded using free security resources available for Splunk like Security Essentials app for Splunk: https://splunkbase.splunk.com/app/3435/
