Note: If a zone server is not being used, this is Not Applicable. Consult with the Tanium System Administrator to verify which firewall is being used as a host-based firewall on the Tanium Zone Server. Access the host-based firewall configuration on the Tanium Zone Server. Validate a rule exists for the following: Port Needed: Tanium Clients to Zone Server over TCP port 17472. If a host-based firewall rule does not exist to allow TCP port 17472, bi-directionally, from Tanium Clients to the Tanium Zone Server, this is a finding.
