title: Client Server socket security
body: <p>Assuming we have a server S and a few Clients (C) and whenever a client update a server, an internal database on the server is updated and replicated to the other clients. This is all done using sockets in an intranet environment. 
  I believe that an attacker can fairly easily sniff this plain text traffic. My colleagues believe I am overly paranoid because we are behind a firewall.</p>
  
  <p>Am I being overly paranoid? Do you know of any exploit (link please) that took advantage of a situation such as this and what ca be done differently. Clients were rewritten in Java but server is still using C++.
  Any thing in code can protect against an attack?</p>
