Client Index Extension requirements

Review the requirements before you install and use Client Index Extension.

Tanium dependencies

Make sure that your environment meets the following requirements.

Component Requirement
Tanium™ Core Platform 7.3.314.4250 or later
Tanium™ Client 7.2.314.3211 or later. Some Tanium solutions that manage the deployment of configuration changes with Tanium Endpoint Configuration might require a higher client version.
Computer groups

When you first log into the Tanium Console after an installation of Tanium Server 7.4.2 or later, the server automatically imports the computer groups that Client Index Extension requires.

For earlier versions of the Tanium Server, or after upgrading from an earlier version, you must manually create the computer groups. See Create computer groups.

Disk space requirements

To install Index normally, a minimum of 1 GB of free space must be available on the drive where Tanium Client is installed.

The amount of space the Index installation uses varies depending on how much space is used on the local disks that are being indexed. The actual space that is required for the Index database is proportional to the number of files and directories on the local disks and what hashes are configured. For a rough estimate, the Index database uses approximately 1 MB of space for each 1 GB of drive space that is used.

Host and network security requirements

Security exclusions

If security software is in use in the environment to monitor and block unknown host system processes, Tanium recommends that a security administrator create exclusions to allow the Tanium processes to run without interference. The configuration of these exclusions varies depending on AV software. For a list of all security exclusions to define across Tanium, see Tanium Core Platform Deployment Reference Guide: Host system security exclusions.
