Work with your support team to meet Splunk Cloud Platform requirements

Work with your support team to make sure your Splunk Cloud Platform environment is ready to install the Splunk Phantom App for Splunk:

Before you begin the installation process, submit a support request to the Splunk Cloud Platform team to make sure the administrative user has the correct privileges. After you have the correct privileges, open access from Splunk Cloud Platform to port 8089 using the Admin Config Service (ACS) API.

1. The Splunk Phantom App for Splunk requires that a user with administrative privileges installs both the Splunk Phantom App for Splunk and Splunk software. In situations where events can't be sent from Splunk Cloud Platform to Splunk Phantom or Splunk SOAR using alert actions, adaptive response actions, or event forwarding, the events are stored in the phantom_retry KV Store collection. The Splunk Phantom App for Splunk requires the admin user to run the phantom_retry.py script every 60 seconds to try to send any events that could not be sent earlier. If the user invoking the phantom_retry.py script is not the admin user, submit a support request to to the Splunk Cloud Platform team to modify the local/inputs.conf file to contain:

   [script://$SPLUNK_HOME/etc/apps/phantom/bin/scripts/phantom_retry.py]
   passAuth = <username>
   

   Also make sure the local/inputs.conf file does not change ownership or permission.
2. Your Splunk Phantom or Splunk SOAR instance must be running in the DMZ or perimeter network with the appropriate firewalls or reverse proxies to support internal connectivity.
3. Splunk Phantom requires a publicly valid certificate chain. The cacerts.pem file must be configured into a single PEM certificate file with the server, intermediate, and root certificates.
