Re: [FW1] [OT] Securing 3270E data stream



Bill,

The short answer is yes (it's not secure).  TN3270 is just a (somewhat odd)
terminal on plain old TELNET.  If you do look at the traffic, remember it's
in EBCDIC (not ASCII).

The long answer is that there's an encryption (TLS/SSL) draft RFC for
TN3270, and it's been implemented in at least a couple of places.  Current
versions of Communications Server for OS/390, for example.  Whether or not
Hummingbird supports it, and has been configured to use it, is another
question.
