Assessment Title

Rule Text

Autoplay must be turned off for non-volume devices.

Description

Discussion Text

Allowing Autoplay to execute may introduce malicious code to a system. Autoplay begins reading from a drive as soon as media is inserted into the drive. As a result, the setup file of programs or music on audio media may start. This setting will disable Autoplay for non-volume devices (such as Media Transfer Protocol (MTP) devices).

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> AutoPlay Policies -> "Disallow Autoplay for non-volume devices" to "Enabled".
