The Tanium Operating System (TanOS) must use FIPS-validated encryption and hashing algorithms to protect the confidentiality and integrity of operating system configuration and user-generated data stored on the host.

Description
Confidentiality and integrity protections are intended to address the confidentiality and integrity of system information at rest when it is located on a storage device within the network device or as a component of the network device. This protection is required to prevent unauthorized alteration, corruption, or disclosure of information when not stored directly on the network device. This requirement addresses the protection of user-generated data as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information.

Who does this work

7 NICE work roles and 7 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-254853r958552_chk)

1. Access the Tanium Server interactively. 2. Log on to the TanOS server with the tanadmin role. 3. Press "A" for "Appliance Configuration Menu," and then press "Enter". 4. Press "A" for "Security," and then press "Enter". 5. Press "X" for "Advanced Security," and then press "Enter". If the FIPS 140-2 setting is currently disabled or persistently disabled, this is a finding.
