title: Security issues I should be aware of with jupyter notebook?
body: <p>I've been using jupyter notebook for about six months now, but I don't really know
  the inner workings and any potential security issues I should be concerned with. </p>
  
  <p>When I run the jupyter command from my console, It seems I am connecting to a
  server which allows me to execute my Python code(?). The server allows access to my PC files -- which means anyone else can access my PC files as well? Would someone potentially be able to delete all my files? Or somehow open a malware script and
  run it on my computer? Are these issues (or similar issues) I need to take additonal precautions against? </p>
  
  <p>What about viruses and malware? Could those be transmitted from the server to my PC easily? Are the servers secure? </p>
  
  <p>Thank you. </p>
