The Tanium endpoint must have the Tanium Server's pki.db in its installation.
Without cryptographic integrity protections in the Tanium Client, information could be altered by unauthorized users without detection. Cryptographic mechanisms used for protecting the integrity o...Rule Medium Severity -
Tanium Trusted Content providers must be documented.
A Tanium Sensor, also called content, enables an organization to gather real-time inventory, configuration, and compliance data elements from managed computers. Sensors gather specific information ...Rule Medium Severity -
Tanium public keys of content providers must be validated against documented trusted content providers.

Tanium Computer Groups must be used to restrict console users from affecting changes to unauthorized computers.
Computer Groups allow a site running Tanium to assign responsibility of specific Computer Groups to specific Tanium console users. By doing so, a desktop administrator, for example, will not have t...Rule Medium Severity -
Documentation identifying Tanium console users, their respective User Groups, Computer Groups, and Roles must be maintained.
System access must be reviewed periodically to verify all Tanium users are assigned the appropriate functional role, with the least privileged access possible to perform assigned tasks being the re...Rule Medium Severity -
The Tanium documentation identifying recognized and trusted folders for Threat Response Local Directory Source must be maintained.
Using trusted and recognized IOC sources may detect and prevent systems from becoming compromised. An IOC stream is a series or stream of IOCs that are imported from a vendor based on a subscriptio...Rule Medium Severity -
The publicly accessible Tanium application must display the Standard Mandatory DOD Notice and Consent Banner before granting access to the application.
Display of a standardized and approved use notification before granting access to the publicly accessible application ensures privacy and security notification verbiage used is consistent with appl...Rule Medium Severity -
Multi-factor authentication must be enabled and enforced on the Tanium Server for all access and all accounts.
To ensure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational user...Rule Medium Severity -
The Tanium application must be configured to send audit records from multiple components within the system to a central location for review and analysis of audit records.
Successful incident response and auditing relies on timely, accurate system information and analysis to allow the organization to identify and respond to potential incidents in a proficient manner....Rule Medium Severity -
The Tanium cryptographic signing capabilities must be enabled on the Tanium Clients to safeguard the authenticity of communications sessions when answering requests from the Tanium Server.
All of Tanium's signing capabilities should be enabled upon install. Tanium supports the cryptographic signing and verification before execution of all Sensors, Questions, Actions, Sensor Libraries...Rule Medium Severity -
Firewall rules must be configured on the Tanium Server for Client-to-Server communications.
In addition to the client-to-server TCP communication that takes place over port 17472, Tanium Clients also communicate to other Tanium-managed computers over port 17472. Without proper firewall co...Rule Medium Severity -
Firewall rules must be configured on the Tanium Zone Server for Client-to-Zone Server communications.
In customer environments using the Tanium Zone Server, a Tanium Client may be configured to point to a Zone Server instead of a Tanium Server. The communication requirements for these Clients are i...Rule Medium Severity -
The Tanium Application Server must be configured to prohibit or restrict the use of organization-defined functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.
To prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restr...Rule Medium Severity -
The Tanium application must enforce a 60-day maximum password lifetime restriction.
Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed at specific intervals. One method of minimizing this risk is to use complex passwords and p...Rule Medium Severity -
The Tanium application must separate user functionality (including user interface services) from information system management functionality.
Application management functionality includes functions necessary for administration and requires privileged user access. Allowing nonprivileged users to access application management functionality...Rule Medium Severity -
The Tanium Server and Client applications must have logging enabled.
Failure to a known state can address safety or security in accordance with the mission/business needs of the organization. Failure to a known secure state helps prevent a loss of confidentiality, i...Rule Medium Severity
