Prerequisites

Before diving into the installation process, let's first discuss the prerequisites for installing Splunk SOAR. First, you need to have a functioning Linux machine (Ubuntu, Centos, or RHEL are all fine). Ensure that you have sudo access or Root permissions on this machine. Your system should have at least 8GB of RAM and a minimum of 2 cores to avoid any performance bottlenecks.

Downloading Splunk SOAR

Once you have ensured the prerequisites are in place, navigate to the official Splunk website and download the Splunk SOAR installation package. If required, register for an account before accessing the download page. Select the version that is suitable for your OS type, and download the .tar.gz file. Remember the location where the file is downloaded as that will be used in the subsequent steps.

Installation Steps

After successfully downloading the file, we can move onto the actual installation process. Here’s a step-by-step walkthrough.

Step 1: Unpack the downloaded file

Firstly, you will need to unpack the downloaded file. To do this, navigate to the directory where you stored the .tar.gz file and run the following command:
tar -xzvf filename.tar.gz

Step 2: Navigate to the unpacked directory

Once the file is unpacked, traverse to the resulting directory using the command:
cd directory_name

Step 3: Run the Installation Script

Within the directory, you will find an installation script. Run this script with root or sudo privileges.
