Using Tanium Client-related Tanium content
The Tanium Core Platform includes Tanium content that facilitates Tanium Client administration.
The Tanium Server imports the Tanium™ Default Content pack when you initially log into the Tanium Console. The pack contains a key set of saved questions, packages, and sensors that you use to get data from endpoints and take actions, including the saved questions and scheduled actions related to the deployment of the Tanium Client itself. To familiarize yourself with the Tanium Client-related content:
- From the Main menu, select Console > Actions > Scheduled Actions and review the actions that are scheduled to run against the action group named Default.
- From the Main menu, select Console > Content > Sensors and search for client-related sensors.
- From the Main menu, select Console > Content > Packages and search for client-related packages.
- From the Main menu, select Console > Content > Saved Questions and search for client-related questions.
The Client Upgrade content pack facilitates upgrading the Tanium Client on Windows endpoints. It is available in all deployments and is categorized as core content on the Tanium Solutions page. To import the ClientUpgradeNonWindows content pack for upgrading the Tanium Client on non-Windows endpoints, consult your Technical Account Manager (TAM).

The Client Service Hardening content pack includes saved questions, packages, and scheduled actions that you can use to restrict how the Tanium Client can be accessed from the local Windows system.
The Tanium Client installs as a normal application on Windows. While the protocols used to communicate with the Tanium Server and peer clients are designed to be secure and prevent rogue sensors or actions, it is still imperative that the Tanium Client itself be protected from an attacker or just a tinkering end user.
|Categories||Client Service Hardening||Contains dashboards related to this content.|
|Dashboards||Control Service State Permissions||
Controlling which accounts have permissions to start and stop services is often the first, and most effective, way you can protect the integrity of your Tanium Client deployment.
Many organizations have given some or all of their end users permissions to be a local administrator. For this reason, Tanium typically recommends you restrict service control to the local SYSTEM account instead.
|Set Client Directory Permissions||Default permissions allow several user types to view or modify files in the Tanium Client directory. While this does not mean that an attacker could cause the agent to run sensors or packages that were not issued by the Tanium Server, because these actions are digitally signed, it could lead to performance issues or extra bandwidth consumption while the information is re-synchronized. Setting the file system permissions to SYSTEM is recommended.|
|Hide From Add-Remove Programs||Controlling whether or not the Tanium Client is viewable in the Add/Remove Programs or simply Programs menu does not directly affect the security of the agent by itself. A user with permissions to uninstall an application would also be able to launch the uninstall manually. This is a useful layer that will help reduce accidental uninstallations and preempt the more inquisitive end users from trying to tamper with the agent. Hiding the client from Add/Remove Programs is considered a best practice and should be used alongside of regular audits of unmanaged assets to look for systems with missing or non-functioning agents.|
