Transaction security

Transaction security (also known as attach-time security, and transaction-attach security) ensures that users that attempt to run a transaction are entitled to do so.

CICS parameters controlling transaction-attach security
You control CICS transaction-attach security checking through CICS system initialization parameters.
Defining transaction profiles to RACF
For those CICS regions running with transaction security checking, define transaction profiles for all transactions that need to be protected from unauthorized access.
Authorization failures and error messages
If a terminal user tries to initiate an unauthorized transaction, CICS issues a security violation message (DFHAC2033) to the terminal.
Protecting non-terminal transactions
For all resource security checking, CICS needs a userid or an ICRX which maps to a userid to check the user's authority to access the resource.
