Description
Ensure that RACF data set rules for all VTAM system data sets restrict access to only network systems programming staff. These data sets include libraries containing VTAM load modules and exit routines, and VTAM start options and definition statements. Failure to properly control VTAM datasets could potentially compromise the network operations.
