Thanks to all that responded both on and off list. Although I have not 
completed a through process that could be used by any system I have concluded 
with reasonable assurances that SSL is not being used by my system. The best 
way in my opinion for those interested, is to utilize the SMF 119 records.

Understand that there are various sub types of this record. Since we run the 
MXG product (and with the help of their excellent support) I quickly ensured 
that TCPIP was requesting that the 119 records be generated and that we were 
only seeing sub types 2,10,20 & 21 being produced. As mention other systems may 
have additional sub types being generated based on TCPIP settings and system 
usage.

But for our system the 02 subtype provided via MXG field TTTTLSSP shows the 
protocol that was used for the TCP connection (SSLV2, SSLV3, TLSV1.0, TLSV1.1 
or TLSV1.2). In our case this field was x'4040' indicating no SSL usage. Also 
the 21 subtype provides via the MXG field NTSSL indicates if an SSL session 
exist. In our case this field was 0 indicating NO SSL SESSION.

Sub type 10 and 20 provided no additional information on SSL usage.

Again thanks to all.

I dare to disagree.
CSFSERV is iCSF SERVcices.
Yes, ICSF services (liek encrypt, decrypt) are protected using CSFSERV
class, but it's not System SSL. Obviously the components are related.

Dennis: I would bet the only candidates using System SSL are TN3270 for
secure emulator connections, FTP (FTPS or FTP/SSL )and possibly HTTPs.
Nothing more. Of course each application should use some port and ports
in use should be know to network folks...
