Description
Similar to any other host-based applications, the Tanium Client is subject to the restrictions other system-level software may place on an operating environment. Antivirus, IPS, encryption, or other security and management stack software may disallow the Tanium Server from working as expected. https://docs.tanium.com/client/client/requirements.html#Host_system_security_exceptions

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-254954r1067672_chk)

Consult with the Tanium system administrator to determine the intrusion prevention software used on the Tanium Clients. Review the settings of the intrusion prevention software. Validate exclusions exist that exclude the Tanium program files from being restricted by intrusion prevention. If exclusions do not exist, this is a finding.

Fix Text (F-58511r867761_fix)

In the host-based intrusion prevention system, ensure the following folders are excluded: Windows (64-bit OS versions) - \Program Files (x86)\Tanium\Tanium Client Windows (32-bit OS versions) - \Program Files\Tanium\Tanium Client macOS - /Library/Tanium/TaniumClient Linux, Solaris, AIX - /opt/Tanium/TaniumClient In the host-based intrusion prevention system, ensure the following processes are excluded: Windows, macOS, Linux - <Tanium Client>/Tools/StdUtils directory or all the files that it contains, including: Windows, macOS, Linux - 7za.exe (Windows) or 7za (macOS, Linux) Windows, macOS, Linux - runasuser.exe (Windows only) Windows, macOS, Linux - runasuser64.exe (Windows only) Windows, macOS, Linux - TaniumExecWrapper.exe (Windows) or TaniumExecWrapper (macOS, Linux) Windows, macOS, Linux - TaniumFileInfo.exe (Windows only) Windows, macOS, Linux - TPowerShell.exe (Windows only) macOS, Linux, Solaris, AIX - <Tanium Client>/TaniumClient macOS, Linux, Solaris, AIX - <Tanium Client>/taniumclient macOS, Linux - <Tanium Client>/distribute-tools.sh macOS, Linux - <Tanium Client>/TaniumCX Windows - <Tanium Client>\TaniumClient.exe Windows - <Tanium Client>\TaniumCX.exe
