Re: AT-TLS Redbook

The target machine is a development system and a client requirement needs its 
implementation.

Re: AT-TLS Redbook

I've said this here before, but it bears repeating: although I'd be the first 
to agree that this sounds stupid/basic, make sure they know NOT to turn it on 
Just Because. We've had two customers who decided it would increase security, 
so they enabled it--for a connection that was already using https. (To be 
precise, it wasn't the customer per se--it was their outsourcer.) The server 
(non-z/OS side) was not amused by the double TLS handshake. Fortunately by the 
second one, I recognized it quickly...

I have a client that in the early stages of planning an AT-TLS installation for 
TLS 1. Is there a Redbook that focuses on AT-TLS?

Re: AT-TLS Redbook

[Colin Paice]

I've written many blog posts on AT-TLS - see here

They cover

   - Getting AT-TLS and PAGENT to work on z/OS – start here.
   

   - configuring pagent
   - Using z/OSMF Network Configuration assistant for TCPIP, to define
   AT-TLS configuration (I found this more work than not using it)
   - programming with AT-TLS
   - secure x3270
   - tracing
   - debugging
   - netstat ((for at-tls)

Please feel free to contact me offline

As far as I’m aware there’s no IBM redbook that exclusively covers z/OS AT-TLS, 
but there are several redbooks that contain relevant chapters or sections. See 
this page for an index:
