Course Overview
In this course you will learn and practice how to conduct investigations using Splunk Enterprise Security features, including Risk Based Alerting, through best practices shared by our security champions, and practice some common tasks using Splunk SOAR.
You will also learn about the PEAK Threat Hunting framework and will apply its basic concepts in a hypothesis-driven threat-hunting exercise.
