Fix Recommendation

Configure the graphical user interface to disable the ability to automount devices.

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.

Create or edit the /etc/dconf/db/local.d/00-No-Automount file and add the following:

[org/gnome/desktop/media-handling]

automount=false

automount-open=false

autorun-never=true

Create or edit the /etc/dconf/db/local.d/locks/00-No-Automount file and add the following:
/org/gnome/desktop/media-handling/automount

/org/gnome/desktop/media-handling/automount-open

/org/gnome/desktop/media-handling/autorun-never

Run the following command to update the database:

# dconf update

Check Contents

Note: If the operating system does not have a graphical user interface installed, this requirement is Not Applicable.

Verify the operating system disables the ability to automount devices in a graphical user interface.

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.

Check to see if automounter service is disabled with the following commands:
# cat /etc/dconf/db/local.d/00-No-Automount

[org/gnome/desktop/media-handling]

automount=false

automount-open=false

autorun-never=true

If the output does not match the example above, this is a finding.

# cat /etc/dconf/db/local.d/locks/00-No-Automount

/org/gnome/desktop/media-handling/automount

/org/gnome/desktop/media-handling/automount-open

/org/gnome/desktop/media-handling/autorun-never

If the output does not match the example, this is a finding.
