    Abstract

    The purpose of this document is to complete the task of introducing Transport Layer Security to z/OS® so IBM Personal Communications (PCOMM) uses TLS security.

    This document walks you through enabling Tunneled Transport Layer Security (TTLS) on your IBM z/OS for use with a PCOMM TN3270 connection. When you complete this task, you require a certificate to access your TN3270 PCOMM session.

    You work with the following products and components:

    • TN3270
    • TCPIP
    • PAGENT
    • INET (maybe)
    • IBM RACF®

    This document assumes that the reader has extensive knowledge of z/OS security administration and these products and components.

    This document is part of the Technical Enablement Series that was created at the IBM Client Experience Centers.
