Mainframe Technical Environment for Auditors [MTSE]

This course has been designed and built for Auditors who come into contact (at any level) with IBM mainframe systems in their daily work. The course encompasses an overview of the z/OS mainframe computing environment, before focusing on the security implications of the environment, as relevant to auditors. Each stage of the course builds upon the previous one, enabling attendees to consolidate what has been learned and see how it will apply to their daily work.

This ten-day Boot Camp course is the essential foundation for the IBM Z Systems enterprise computing environment and its flagship operating system, z/OS. The course introduces the concepts and terminology encountered and used by IS personnel every day and explains them in an easily understandable manner.

The concepts, facilities, and use of TSO and IBM's Interactive System Productivity Facility (ISPF) are taught during this week, with a focus on the functions for data editing and dataset management. The week concludes with z/OS Job Control Language (JCL). Attendees will be introduced to the coding of job control statements to execute programs and access datasets in a z/OS environment. They will also learn how to write and test catalogued procedures and be introduced to some advanced functions and utilities.

This five-day course is Part 3 of RSM's newly designed and built z/OS Foundation Skills programmer. The previous two parts have introduced students to the Z Systems computing environment at a conceptual and terminological level, the use of TSO/ISPF, the use of z/OS JCL, and z/OS and JES2 from an operational perspective.

This part of the programmer now examines the System Z mainframe environment at a technical level, introducing the architecture and explaining the z/OS operating system. This is followed by an overview of z/OS security with RACF. The course concludes with an introduction to networks in a Z Systems environment.
