Discussion

Off-loading ensures audit information is not overwritten if the limited audit storage capacity is reached and also protects the audit record in case the system/component being audited is compromised. Off-loading is a common process in information systems with limited audit storage capacity. The audit storage on the IDPS is used only in a transitory fashion until the system can communicate with the centralized log server designated for storing the audit records, at which point the information is transferred. However, DoD requires that the log be transferred in real time, which indicates that the time from event detection to off-loading is seconds or less. This does not apply to audit logs generated on behalf of the device itself (management).

Fix Text

Configure the DBN-6300 to be connected to the syslog server. Also configure the DBN-6300 to include audit records in the syslog message feed. Navigate to Settings >> Advanced >> Syslog. Enter the syslog connection information (port and IP address) and push the "enabled" button for both "TCP" and "enable". 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. If the "Use System Syslog" button is not set to "Yes", press the "Yes" button. Click on "Commit".

Check Content

Audit records are automatically backed up on a real-time basis via syslog when enabled. 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, process an account action. Confirm the presence of a syslog message on the syslog server containing the details of this account action. If the DBN-6300 is not connected to the syslog server, or if the syslog server is connected but the message containing the information with the details of this account action is not there, this is a finding.
