| 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 | ||||

Check Text (C-271679r1091749_chk)
This requirement assumes the use of the OL 9 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 that OL 9 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:
$ grep system-db /etc/dconf/profile/user
system-db:local
Check that the automount setting is locked from nonprivileged user modification with the following command:
Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". This path must be modified if a database other than "local" is being used.
$ grep 'autorun-never' /etc/dconf/db/local.d/locks/*
/org/gnome/desktop/media-handling/autorun-never
If the command does not return at least the example result, this is a finding.
Fix Text (F-75636r1091748_fix)
Configure the 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
