Introduction

  • Program Name: Commonwealth Bank SOC Analyst Training Program
  • Duration: 5 weeks
  • Platform: The Forage
  • Skills: SOC, Splunk, SIEM, Cybersecurity
  • The first step of the program was to install Splunk Enterprise.
  • The configuration and the ability to run it on a virtual machine was a challenge.

Installing Splunk Enterprise

Downloaded Splunk Enterprise from this website and installed Splunk Enterprise on a virtual machine (VM) running Ubuntu 24.04.02 LTS.

Post-installation configuration

  • Because of my virtual machine, I searched for a shortcut in the applications menu and couldn't find it. So I had to start Splunk from the terminal.
cd /opt/splunk/bin
sudo ./splunk start --accept-license
