Install Splunk Phantom using the Amazon Marketplace Image

Install Splunk Phantom for AWS from the AWS Marketplace in the security category.

With the release of Splunk Phantom 4.10, the AMI version of Splunk Phantom is for an unprivileged installation, meaning the the application runs under the phantom user account, and not as root.

• The base installation directory for the unprivileged AMI is /opt/phantom/.
• The custom HTTPS port is 9999, but the Splunk Phantom UI is still available on port 443.

Prerequisites

Your AWS instance must meet or exceed the requirements for either an evaluation system for evaluation or Proof of Value testing, or a production system for production use, and must include:

• A supported operating system. See Supported operating systems.
• Sufficient storage. See System requirements for production use.
