Normal preset security

CICS preset terminal security allows you to associate a userid permanently with a terminal, or console, that is defined to CICS. This means that CICS implicitly signs on the device when it is being installed, instead of a subsequent sign-on of that terminal by a user. Typically, you define preset security for devices without keyboards, such as printers, at which users cannot sign on.

You can also use the normal preset security on ordinary display terminals as an alternative to terminal user security. This permits anyone with physical access to a terminal with preset security to enter the transactions that are authorized for that terminal. The terminal remains signed on as long as it is installed, and no explicit sign-off can be performed against it. If the userid associated with a display terminal with preset-security has been authorized to use any sensitive transactions, ensure that the terminal is in a secure location to which access is restricted. Preset-security might be appropriate, for example, for the terminals physically located within a CICS network control center.

You can use preset-security to assign a userid with lower authority than the default, for terminals in unrestricted areas.

For example, to define a terminal with preset-security, use RACF® and CICS (CEDA) commands as follows:
ADDUSER userid NAME(preset_terminal_user_name) OWNER(owner_userid or group_id)
               DFLTGRP(group_name)
CEDA DEFINE TERMINAL(cics_termid) NETNAME(vtam_termid) USERID(userid)
            TYPETERM(cics_typeterm)
