SV-45077r1_rule ActiveX opt-in prompt must be disallowed.

Vulnerability discussion

This policy setting allows you to turn off the ActiveX opt-in prompt. The ActiveX opt-in prevents Websites from loading any COM object without prior approval. If a page attempts to load a COM object that Internet Explorer has not used before, an information bar will appear asking the user for approval. If you enable this policy setting, the ActiveX opt-in prompt will not appear. Internet Explorer does not ask the user for permission to load a control, and will load the ActiveX if it passes all other internal security checks. If you disable or do not configure this policy setting the ActiveX opt-in prompt will appear.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
