Dependancies
Rather than reinventing the wheel Security Monitoring for Splunk works on the premise that there are many many great apps on splunkbase that do a great job, and therefore leverages those rather than reinventing the 'wheel'. As such you should download and install the following apps before configuring Security Monitoring for Splunk.
