Vulnerability discussion

Administrators need to be aware of activity that occurs regarding their network device management account. Providing administrators with information regarding the number of unsuccessful attempts made to login to their account allows them to determine if any unauthorized activity has occurred. Without this information, the administrator may not be aware that unauthorized activity has occurred. This incorporates all methods of login, including, but not limited to, SSH, HTTP, HTTPS, and physical connectivity.

Check content

Determine if the network device is either configured to notify the administrator of the number of unsuccessful login attempts since the last successful login or configured to use an authentication server which would perform this function. If the administrator is not notified of the number of unsuccessful login attempts since the last successful login, this is a finding.

Fix text

Configure the network device to notify the administrator of the number of unsuccessful login attempts since the last successful login, upon successful login.

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.
