Vulnerability discussion

The kernel extension for Wi-Fi network devices such as Airport must be removed to ensure that users will not be able to reactivate wireless networking at a later time. System updates will sometimes replace deleted kernel extensions. Administrator users may need to periodically check to ensure that the file remains deleted. Alternately, the wireless card hardware may be removed from the system.

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.
