BMC Mainframe: TCP/IP Security in a z/OS Environment using Policy Agent & RACF

The course is developed and delivered by © RSM Technology.

Large system network security requirements have become much more stringent and complex over recent years, following the advent of TCP/IP and Internet interfaces. This essential new course explains how to set up and administer vitally important security for the z/OS networking environment.

The course gives attendees a sound understanding of how the Communications Server, along with other elements in z/OS including RACF, Policy Agent (PAGENT), z/OSMF and the Network Configuration Assistant, provide multiple IP security functions. These protect data privacy and integrity for z/OS and protect system resources from unauthorized access.

This course includes extensive hands-on exercises, with each student being given their own z/OS system on which to work.
