Overview

Finding ID Version Rule ID IA Controls Severity
V-46581 DTBI116-IE11 SV-59445r1_rule DCMC-1 Medium
Description
This policy setting allows management of whether ActiveX controls marked safe for scripting can interact with a script. If you enable this policy setting, script interaction can occur automatically without user intervention. ActiveX controls not marked as safe for scripting should not be executed. Although this is not a complete security measure for a control to be marked safe for scripting, if a control is not marked safe, it should not be initialized and executed.
