Vulnerability discussion

This policy setting controls whether or not the “Open File – Security Warning” prompt is shown when launching executables or other unsafe files. If you do not configure this policy setting, users can configure the prompt behavior. By default, execution is blocked in the Restricted Zone, enabled in the Intranet and Local Computer Zones, and set to prompt in the Internet and Trusted Zones.

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.
