Tanium Operating System (TanOS) must automatically terminate a user session after organization-defined conditions or trigger events requiring session disconnect.

Description
Automatic session termination addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., network disconnect). A logical session (for local, network, and remote access) is initiated whenever a user (or process acting on behalf of a user) accesses an organizational information system. Such user sessions can be terminated (and thus terminate user access) without terminating network sessions.

Who does this work

7 NICE work roles and 5 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-254859r958636_chk)

1. Sign in to the TanOS console as a user with the tanadmin role. 2. Enter "A" to go to the "Appliance Configuration" menu. 3. Enter "A" to go to the "Security" menu. 4. Enter "X" to go to the "Advanced Security" menu. 5. Enter "5" to go to "Set Menu Timeout". 6. See the current setting for timeout, if this does not match the organizationally defined standard, this is a finding.
