Automatically mounting file systems permits easy introduction of unknown devices, thereby facilitating malicious activity. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163
Note: This requirement assumes the use of the RHEL 10 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 RHEL 10 disables the graphical user interface automount function. Disable the setting with the following command: $ gsettings get org.gnome.desktop.media-handling automount-open false If "automount-open" is set to "true" and is not documented with the information system security officer as an operational requirement, this is a finding.
Configure RHEL 10 GNOME to disable automated mount of removable media. Note: The example below is using the database "local" for the system. If the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory. Update the "/etc/dconf/db/local.d/00-security-settings" database file with the following lines: $ sudo vi /etc/dconf/db/local.d/00-security-settings [org/gnome/desktop/media-handling] automount-open=false Update the dconf system databases: $ sudo dconf update
