Disable Geolocation in GNOME3

An XCCDF Rule

Description

GNOME allows the clock and applications to track and access location information. This setting should be disabled as applications should not track system location. To configure the system to disable location tracking, add or set enabled to false in /etc/dconf/db/local.d/00-security-settings. For example:

[org/gnome/system/location]
enabled=false

To configure the clock to disable location tracking, add or set geolocation to false in /etc/dconf/db/local.d/00-security-settings. For example:

[org/gnome/clocks]
geolocation=false

Once the settings have been added, add a lock to /etc/dconf/db/local.d/locks/00-security-settings-lock to prevent user modification. For example:

/org/gnome/system/location/enabled
/org/gnome/clocks/geolocation

After the settings have been set, run dconf update.

Rationale

Power settings should not be enabled on systems that are not mobile devices. Enabling power settings on non-mobile devices could have unintended processing consequences on standard systems.
