Protecting CICS load module data sets

To prevent unauthorized or accidental modification of hlq.SDFHAUTH, you must protect it with RACF.

Without protection, the integrity and security of your MVS system are at risk. Additionally, if you require protection against the unauthorized use of DFHSIP, do not place this module in the LPA and do not include hlq.SDFHAUTH in the MVS LNKLST unless DFHSIP is RACF®-protected as a controlled program with a profile in the RACF PROGRAM resource class.

You must also RACF-protect the other libraries, including hlq.SDFHLOAD, that make up the STEPLIB and DFHRPL library concatenations.

For information about authorizing access to CICS® data sets, see Implementing RACF protection in a single CICS region.
