What is the first step when preparing to install ES?

The first step when preparing to install Splunk Enterprise Security (ES) is to determine the size and scope of the installation. This step is crucial because it lays the foundation for the entire installation process. Understanding the size and scope involves assessing the organization's security needs, the volume of data that will be ingested, the number of users who will access the system, and the anticipated future growth.

By evaluating these factors upfront, you can make informed decisions about the necessary resources, such as hardware specifications, scaling requirements, and the configuration of the Splunk environment. This thorough understanding helps to ensure that the installation is not only adequate for current needs but also flexible enough to accommodate future demands. Ultimately, properly gauging the size and scope ensures a successful deployment that meets performance and usability expectations.
