AT-TLS in a Nutshell takes you on a quick tour of the Application Transparent Transport Layer Security feature of z/OS Communications Server. Starting with a very high level review of SSL/TLS, this video goes on to describe what AT-TLS is, how it works, why you would want to use it, and gives you a quick snapshot of AT-TLS configuration. From there, we point you to references you can use to start pursuing your own AT-TLS deployment.
