You can restrict client access to a mainframe processing environment in the following ways:
Require client identification for access to TRS. Only clients specifically defined to a TRS are allowed to send requests through TRS.
(For LU 6.2 only) Restrict access to mainframe connections. Each client login is assigned a group of connections it can use.
Restrict access to mainframe transactions. Each client login is assigned a group of permitted mainframe transactions.
By default, TRS security is automatically enabled when you start TRS. You can specifically override it by setting the TRS Security configuration property to no.
