ActiveX Control

One of the most useful capabilities of App Rules is the ability to distinguish between different types of ActiveX or Flash network traffic. This allows you to block games while permitting Windows updates. Prior to App Rules, you could configure SonicOS to block ActiveX with POLICY | Security Services > Content Filter, but this blocked all ActiveX controls, including your software updates.

App Rules achieves this distinction by scanning for the value of classid in the HTML source. Each type of ActiveX has its own class ID, and the class ID can change for different versions of the same application.

Some ActiveX types and their classid’s are shown in ActiveX Types and Classids.

ActiveX Match Object shows an ActiveX type match object that is using the Macromedia Shockwave class ID. You can create a policy that uses this match object to block online games or other Shockwave-based content.

ActiveX Match Object

You can look up the class ID for these Active X controls on the Internet, or you can view the source in your browser to find it. For example, Example of source file with class ID shows a source file with the class ID for Macromedia Shockwave or Flash.
