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

ℹ️ Check
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
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
