My Adventures with TCP/IP Port Security and RACF on z/OS

In the ever growing world of TCPIP security the number of RACF SERVAUTH general resource class profiles has skyrocketed. In this session we will focus on a critical, and often overlooked, aspect of TCPIP security ‐ ports. Learn the key aspects of how to secure all TCP & UDP ports on your mainframe with RACF. We will explore an implementation strategy and how the mainframe has an edge in this mission-critical area of TCPIP security. If you don't take control of your ports, then someone else will!



z/OSMF provides a web-based interface that allows you to manage various aspects of your z/OS systems through a browser at any time, from any location. One asks, ok, what does that have to do with security. Well, using z/OSMF requires sufficient authority in z/OS. Specifically, on the z/OS system to be managed, the resources to be accessed on behalf of z/OSMF users (data sets, operator commands, and so on) are secured through RACF. This session will describe user experiences on setting up z/OSMF with a focus on the security requirements.



Permission to certain UNIXPRIV class profiles can provide users with the ability to perform specific Superuser functions without requiring full Superuser authority. Other UNIXPRIV profiles influence RACF's decision as whether a user is allowed to access a file or directory. This presentation will introduce you to all the UNIXPRIV profiles and discuss how to make best use of them.


RACF Grouping Class Profiles

Gain a better understanding of the contents and administration of grouping class profiles. We will delve
into the relationship and interaction of member and grouping classes. RACF merges the profiles in a member/ grouping class pair during RACLISTing to form a combined set of profiles for access authorization checking. Find out how RACF builds this set and what values it chooses for UACC, AUDIT, WARNING, and permissions.


Experience with Two Factor Authentication (2FA) on z/OS
Have you authenticated to your z/OS system with a token yet ? Come and discuss why you may want to do this. Which users you may want to target. We will discuss various software issues experienced, and some non technical issues you may not have thought about yet. While both IBM and CA security managers support MFA, there may be other issues that you may not have considered yet.
