Consult with the Tanium System Administrator to verify which firewall is being used as a host-based firewall on the Tanium Module Server. Access the host-based firewall configuration on the Tanium Module Server. Validate a rule exists for the following: Port Needed: Tanium Server to Tanium Module Server over TCP port 17477. If a host-based firewall rule does not exist to allow TCP port 17477, from the Tanium Server to the Tanium Module Server, this is a finding. Consult with the network firewall administrator and validate rules exist for the following: Allow TCP traffic on port 17477 from the Tanium Server to the Tanium Module Server. If a network firewall rule does not exist to allow TCP traffic on port 17477 from the Tanium Server to the Tanium Module Server, this is a finding.
