Title

ActiveX controls marked safe for scripting must be disallowed (Restricted Sites zone). (Cat II impact)

Discussion

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.
