Overview

This course explains how to set up security for the z/OS networking environment. With the advent of TCP/IP and the Internet, network security requirements have become more stringent and complex.
The Communications Server, along with other elements in z/OS including RACF and Policy Agent (PAGENT), provides IP security functions. These protect data privacy and intergrity for z/OS, and protect system resources from unauthorized access.
This is a 'workshop' style course, and attendees will work through extensive hands-on exercises, on their own z/OS system.

This course is also available 'on demand' (minimum 2 students) for additional public presentations or for one-company, on-site presentations.

Prerequisites

Attendees will need a sound knowledge of TCP/IP concepts and protocols (this can be gained by attending the RSM course TCP/IP Fundamentals), and TCP/IP in a z/OS environment (this can be gained by attending the RSM course z/OS Communications Server Part 2 - Implementing TCP/IP under z/OS. A good knowledge of UNIX System Services is also needed, which can be gained by attending RSM's course Using RACF under UNIX System Services (USS).
