Title

Firewall rules must be configured on the Tanium Server for server-to-database communications. (Cat II impact)

Discussion

The Tanium Server can use either a SQL Server relational database management system (RDBMS) installed locally to the same device as the Tanium Server application or a remote dedicated or shared SQL Server instance. Using a local SQL Server database typically requires no changes to network firewall rules since all communication remains on the Tanium application server device. To access database resources installed to a remote device, however, the Tanium Server service communicates over the port reserved for SQL, by default port 1433, to the database. Port Needed: Tanium Server to Remote SQL Server over TCP port 1433. Network firewall rules: Allow TCP traffic on port 1433 from the Tanium Server device to the remote device hosting the SQL Server RDBMS. For more information, refer to https://docs.tanium.com/platform_install/platform_install/reference_network_ports.html.

Check Content

Consult with the Tanium system administrator to verify which firewall is being used as a host-based firewall on the Tanium Server. 1. Access the Tanium Server. 2. Log on to the server with an account that has administrative privileges. 3. Access the host-based firewall configuration on the Tanium Server. 4. Validate a rule exists for the following: Port Needed: Tanium Server to Remote SQL Server over TCP port 1433. If a host-based firewall rule does not exist to allow Tanium Server to Remote SQL Server over TCP port 1433, this is a finding. Consult with the network firewall administrator and validate rules exist for the following: Allow traffic from Tanium Server to Remote SQL Server over TCP port 1433. If a network firewall rule does not exist to allow traffic from Tanium Server to Remote SQL Server over TCP port 1433, this is a finding.

Fix Text

1. Configure host-based firewall rules on the Tanium Server to include the following required traffic: Allow TCP traffic on port 1433 from the Tanium Server to the Remote SQL Server. 2. Configure the network firewall to allow the above traffic.
