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
  • INET (maybe)

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.
