Assessment Title

Rule Text

Autoplay must be disabled for all drives.

Description

Discussion Text

Allowing Autoplay to execute may introduce malicious code to a system. Autoplay begins reading from a drive as soon media is inserted into the drive. As a result, the setup file of programs or music on audio media may start. By default, Autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive) and on network drives. Enabling this policy disables Autoplay on all drives.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Assessment Script Powered by AISyntax-verified

A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual ms_windows_2012_and_2012_r2_ms target this check assesses.

# OVAL Definition: oval:mil.disa.fso.windows:def:4492

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> AutoPlay Policies -> "Turn off AutoPlay" to "Enabled:All Drives".
