Title

The system is configured to allow installation of printers using kernel-mode drivers. (Cat II impact)

Discussion

Kernel-mode drivers are drivers that operate in kernel mode. Kernel mode allows virtually unlimited access to hardware and memory. A poorly written kernel driver may cause system instability and data corruption. Malicious code inserted in a kernel-mode driver has almost no limit on what it may do. Most modern printers do not require kernel-mode drivers.

Fix Text

Configure the system to prevent it from allowing the installation of kernel-mode drivers by setting the policy value for Computer Configuration -> Administrative Templates -> Printers “Disallow Installation of Printers Using Kernel-mode Drivers” to “Enabled”.
