Using SYSVIEW and the options to access to SYSVIEW interfaces are open to all users. How to restrict it only to the system programmers.
If using SYSVIEW internal security, the easiest way to accomplish this is to modify the 'Miscellaneous Section' of the DEFAULT User Group and set 'Interfaces' to the ones that are allowed for the users.
For example, for TSO or VTAM, if you set it to NONE then the users wouldn't be able to logon at all.
Create a separate User Group (maybe call it SYSPROGS) that contains the IDs of all the SYSPROGs in the 'User Ids Section' that should have access. The SYSPROGS group could be created by copying DEFAULT, just make sure the 'Interfaces' is set back to ALL in the Miscellaneous Section.
