This presentation is intrended to show and demonstrate how powerful can be IBM zSecure a quick overview about internal criteria used by IBM Workloadwith RACF to fully protect IBM Scheduler for z/OS (IWSz) resources, especially with the new modern needs of addressing DEVOPS issues of allowing developers to access IWSz in a limited way enabling work only with batch applications and objects they are responsible for. This is also achieved with last IWSz 9.3 enhancements, and can be protected in the best way by using zSecure Command Verifier. I created this presentation for several Workload Automarion and zSecure User Groups (Denmark, France, UK and Germany in Copenhagen, Paris, London, Nuremberg, Frankfurt).
