Vulnerability discussion

Upon gaining access to a network device, an attacker will often attempt to create a persistent method of reestablishing access. One way to accomplish this is to modify an account. This control does not apply to the account of last resort or root account. DoD prohibits local user accounts on the device, except for an account of last resort and (where applicable) a root account.Account management functions include assignment of group or role membership; identifying account type; specifying user access authorizations (i.e., privileges); account removal, update, or termination; and administrative alerts.With the DBN-6300, audit records are automatically backed up on a real-time basis via syslog when enabled.

Check content

Verify the DBN-6300 is connected to the syslog server. Navigate to Settings >> Advanced >> Syslog. Verify that the syslog services are set to "on", the syslog server information is valid, and the syslog server has connected. Navigate to Settings >> Advanced >> Audit Log. Verify that the Audit Syslog, "Use System Syslog" button is set to "Yes" and that the Audit Configuration Categories are all checked for Audit Log, Syslog, and Audit Console. Following this verification, process an account modification. Confirm the presence of a syslog message on the syslog server containing the information for successful account modification. If the DBN-6300 is not connected to the syslog server, or if the syslog server is connected but the message containing the information that a successful account modification has just occurred is not there, this is a finding.

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.
