Vulnerability discussion

An HTML5 based application, the Tanium Console runs from any device with a browser that supports HTML5. For security, the HTTP and SOAP communication to the Tanium Server is SSL encrypted, so the Tanium Server installer configures the server to listen for HTTP and SOAP requests on port 443. Without a proper connection to the Tanium Server, access to the system capabilities could be denied.Port Needed: To Tanium Server over TCP port 443.Network firewall rules:Allow HTTP traffic on TCP port 443 from any computer on the internal network to the Tanium Server device.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. Access the host-based firewall configuration on the Tanium Server. Validate a rule exists for the following: Port Needed: From only designated Tanium console user clients to Tanium Server over TCP port 443. If a host-based firewall rule does not exist to allow only designated Tanium console user clients to Tanium Server over TCP port 443, this is a finding. Consult with the network firewall administrator and validate rules exist for the following: Allow TCP traffic from only designated Tanium console user clients to Tanium Server over TCP ports 443. If a network firewall rule does not exist to allow traffic from only designated Tanium console user clients to Tanium Server over TCP port 443, this is a finding.

Fix text

Configure host-based firewall rules on the Tanium Server to include the following required traffic: Allow TCP traffic on port 433 to the Tanium Server from designated Tanium console user clients. Configure the network firewall to allow the above traffic.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
