2.3.4.1 (L2) Ensure 'Devices: Prevent users from installing printer drivers' is set to 'Enabled'

Information

For a computer to print to a shared printer, the driver for that shared printer must be installed on the local computer. This security setting determines who is allowed to install a printer driver as part of connecting to a shared printer.

The recommended state for this setting is: Enabled

Note: This setting does not affect the ability to add a local printer. This setting does not affect Administrators.

It may be appropriate in some organizations to allow users to install printer drivers on their own workstations. However, in a high security environment, you should allow only Administrators, not users, to do this, because printer driver installation may unintentionally cause the computer to become less stable. A malicious user could install inappropriate printer drivers in a deliberate attempt to damage the computer, or a user might accidentally install malicious software that masquerades as a printer driver. It is feasible for an attacker to disguise a Trojan horse program as a printer driver. The program may appear to users as if they must use it to print, but such a program could unleash malicious code on your computer network.

Solution

To establish the recommended configuration via GP, set the following UI path to Enabled :

Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\Security Options\Devices: Prevent users from installing printer drivers

Impact:

Only Administrators will be able to install a printer driver as part of connecting to a shared printer. The ability to add a local printer will not be affected.
