Discussion

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. Satisfies: SRG-OS-000392-GPOS-00172, SRG-OS-000032-GPOS-00013

The TELNETPARMS SMFINIT statement is coded with the TYPE119 operand within each TELNETPARMS statement block.

The TELNETPARMS SMFTERM statement is coded with the TYPE119 operand within each TELNETPARMS statement block.

Note: The SMFINIT and SMFTERM statement can appear in both TELNETGLOBAL and TELNETPARM statement blocks. If duplicate statements appear in the TELNETGLOBALS, TELNETPARMS, Telnet uses the last valid statement that was specified.
