There is an client-server app written in Java. They communicate to each other somehow. Unfortunately our technician is not reliable (we are going to fire him).
He accepted that application from the company. They are claiming that everything is secure.
I am not a technican person, can you help me to find out if communication between client and server is encrypted?
I have access to the server. The server is Windows Server.
One suggested to use
netstat but I don't know how to use it (which parameters to provide)
