Let us take a brief look at the assets that CICS® manages, and potential exposures. The assets are the application programs, the application data, and the application output. To prevent disclosure, destruction, or corruption of these assets, you must first safeguard the CICS system components themselves.
There are two distinct areas from which exposures to the CICS system can arise. The first of these is from sources external to CICS. You can use RACF® data set protection as the primary means of preventing unauthorized access, from either TSO users or batch jobs, to the assets CICS manages.
