Vulnerability discussion

If a user cannot explicitly end an operating system session, the session may remain open and be exploited by an attacker; this is referred to as a zombie session.Information resources to which users gain access via authentication include, for example, local workstations and remote services. For some types of interactive sessions, including, for example, remote logon, information systems typically send logoff messages as final messages prior to terminating sessions.

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.
