Fix Recommendation

Configure the "DEFAULT" statement to specify "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.

Configure each "CONSOLE" statement to specify 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.
