Vulnerability discussion

User Account Control (UAC) is a security mechanism for limiting the elevation of privileges, including administrative accounts, unless authorized. Denying elevation requests from standard user accounts requires tasks that need elevation to be initiated by accounts with administrative privileges. This ensures correct accounts are used on the system for privileged tasks to help mitigate credential theft.

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.
