Fix Recommendation

Configure the operating system to prevent a user from overriding a session lock after a 15-minute period of inactivity for graphical user interfaces.

Create a database to contain the system-wide screensaver settings (if it does not already exist) with the following command:

Note: The example below is using the database "local" for the system, so if the system is using another database in /etc/dconf/profile/user, the file should be created under the appropriate subdirectory.

# touch /etc/dconf/db/local.d/locks/session

Add the setting to lock the session idle delay:

/org/gnome/desktop/session/idle-delay

Check Contents

Verify the operating system prevents a user from overriding session idle delay after a 15-minute period of inactivity for graphical user interfaces.

Note: If the system does not have GNOME installed, this requirement is Not Applicable. The screen program must be installed to lock sessions on the console.

Determine which profile the system database is using with the following command:
# grep system-db /etc/dconf/profile/user

system-db:local

Check for the session idle delay setting 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 -i idle-delay /etc/dconf/db/local.d/locks/*

/org/gnome/desktop/session/idle-delay

If the command does not return a result, this is a finding.
