Description
Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163, SRG-OS-000480-GPOS-00227

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-274872r1107297_chk)

Note: This requirement assumes the use of the Ubuntu 24.04 LTS default graphical user interface, the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable. Verify Ubuntu 24.04 LTS disables ability of the user to override the graphical user interface autorun setting. Determine which profile the system database is using with the following command: $ gsettings writable org.gnome.desktop.media-handling autorun-never false If "autorun-never" is writable, the result is "true". If this is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.

Fix Text (F-78878r1107296_fix)

Configure the Ubuntu 24.04 LTS GNOME desktop to not allow a user to change the setting that disables autorun on removable media. Add the following line to "/etc/dconf/db/local.d/locks/00-security-settings-lock" to prevent user modification: /org/gnome/desktop/media-handling/autorun-never Update the dconf system databases: $ sudo dconf update
