Description
The TN3270 Telnet Server can provide audit data in the form of SMF records. The SMF data produced provides information about individual sessions. This data includes the VTAM application, the remote and local IP addresses, and the remote and local IP port numbers. Failure to collect and retain audit data may contribute to the loss of accountability and hamper security audit activities.
