Issue/Introduction
Is the traffic going back and forth between the client and RmiServer encrypted?
Environment
Release : 9.4
Component : APPLICATIONS MANAGER
Resolution
The client to Server communication in Applications Manager is encrypted. The connection is using Java and Java sockets, which uses Java Secure Socket Extension (JSSE).
JSSE uses both the Secure Sockets Layer (SSL) protocol and the Transport Layer Security (TLS) protocol to provide secure, encrypted communications between your clients and servers.
Please refer to Oracle for more information.
To see some additional information regarding encryption, enable client debug, launch the client and log in, and review the client.log file. The below information or similar can be seen:

Please note that the communication security for these connections is handled by Client and Server Java and the settings configured within Java such as the java.security file.
