Vulnerability discussion

Unsecure apps for Office, which are apps that have web page or catalog locations that are not SSL-secured (https://), and/or are not in users' Internet zones may allow data to be transmitted/accessed via clear text to outside sources. By configuring this policy to be disabled, users will be prevented from transmitting/accessing data in a nonsecure manner.

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.
