The DBN-6300 must automatically audit account enabling actions.

Description
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail that documents the creation of application user accounts and notifies administrators and ISSOs. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes. With the DBN-6300, audit records are automatically backed up on a real-time basis via syslog when enabled.

Check Text ( C-76609r1_chk )
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 the Audit Configuration Categories are all checked for Audit Log, Syslog, and Audit Console. Following this verification, enable an account. Confirm the presence of a syslog message on the syslog server containing the date and time of this last logon. 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 an account has been enabled is not there, this is a finding.
