OTHER SECURITY MANAGEMENT TECHNIQUES - IBM Mainframe

Some other security management techniques under CICS are FCT SERVREQ option and EIBTRMID option.

The FCT definition macro DFHFCT has an option SERVREQ. through which the type of access by CICS to a file can be restricted. So in the DFHFCT macro for the option Service Request, SERVREQ can be coded so that only specified services are granted to the application program. If a CICS application program requests an unauthorized service, it will be rejected with an 1NVREQ condition.

This gives the application program the authority to read and update the dataset. The other options are ADD, BROWSE and DELETE.

EIBTRMID contains the 4 character terminal id defined in the Terminal Control Table (TCT) for the terminal, which the current transaction is associated. It can be checked whether the terminal is authorized for this transaction. So in the beginning of an application program, the programmer can check whether the transaction is being initiated from the authorized terminal and if not the task can be terminated.
