The data security monitor (ICHDSM00, usually called DSMON) is a batch program that allows authorized users to obtain a set of reports that provide information about the current status of your installation's data security environment.

These reports help you (1) check the initial steps you took to establish system security and (2) make additional security checks periodically. If the DSMON program (ICHDSM00) is defined in the PROGRAM class (that is, it is a controlled program), the user must be authorized through its access list before the program can be run. If DSMON is not a controlled program, the user must have the AUDITOR attribute to run DSMON and produce reports. (For more information on controlled programs, see Protecting programs.)

For more information on the DSMON reports, see Using the data security monitor (DSMON) or z/OS Security Server RACF Auditor's Guide.
