title: Sending zeroMQ messages to/from localhost - secure?
body: <p>I am trying to use zeroMQ for communicating between 2 processes. The message contains instructions from one process for the second to execute, so that from a security perspective it is quite important that only the proper messages are sent and received. </p>
  
  <p>If I am worried about 3rd parties who may try to intercept or send malicious messages to the process, am I correct in assuming that as long as my messages are sent/received on IP 127.0.0.1 i am always safe? or is there any circumstance where this can be compromised?</p>
  
  <p>Thanks for the help all!</p>
