Assessment Title

Rule Text

The default Autorun behavior must be configured to prevent Autorun commands.

Description

Discussion Text

Allowing Autorun commands to execute may introduce malicious code to a system. Configuring this setting prevents Autorun commands from executing.

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

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> AutoPlay Policies -> "Set the default behavior for AutoRun" to "Enabled:Do not execute any autorun commands".
