____ The "DEFAULT" statement for each CONSOLxx member specifies "LOGON(REQUIRED)" or "LOGON(AUTO)".

____ The "CONSOLE" statement for each console assigns a unique name using the "NAME" parameter.

____ The "CONSOLE" statement for each console specifies "AUTH(INFO)". Exceptions are the "AUTH" parameter is not valid for consoles defined with "UNIT(PRT)" and specifying "AUTH(MASTER)" is permissible for the system console.

Fix Text (F-3247r2_fix)
Ensure that the "DEFAULT" statement specifies "LOGON(REQUIRED)" so that all operators are required to log on prior to entering z/OS system commands. At the discretion of the ISSO, "LOGON(AUTO)" may be used. If "LOGON(AUTO)" is used assure that the console userids are defined with minimal access. See ACP00292. Ensure that each "CONSOLE" statement specifies an explicit console NAME. And that "AUTH(INFO)" is specified, this also including extended MCS consoles. "AUTH(MASTER)" may be specified for systems console. Note: The site should be able to determine the system consoles. However, it is imperative that the site adhere to the "DEFAULT" statement requirement.
