Vulnerability discussion

This is a Category 1 finding because users and user groups that are assigned this right can bypass all security protective mechanisms that apply to all users, including administrators. Accounts with this right should have passwords with the maximum length and be kept in a locked container accessible only by the IAO and his designated backup. Some applications require this right to function. Any exception needs to be documented with the IAO.

Acceptable forms of documentation include vendor published documents and application owner confirmation.

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.
