Overview

Finding ID Version Rule ID IA Controls Severity
V-22160 DTBI880 SV-40739r1_rule ECSC-1 Medium
Description
This policy setting controls whether or not the user is prompted to allow ActiveX controls to run on web sites other than the web site that installed the ActiveX control. If the user were to disable the setting for the zone, malicious ActiveX controls could be executed without the user's knowledge. Disabling this setting would allow the possibility for malicious ActiveX controls to be executed from non-approved domains within this zone without the user's knowledge. Enabling this setting enforces the default value and prohibits the user from changing the value. Web sites should be moved into another zone if permissions need to be changed.
