Firewall rules must be configured on the Tanium Server for server-to-database communications.

Description
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.

ℹ️ Check
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
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.
