title: Can selenium Grid and Node URLs be used with security?
body: <p>I am in a situation where I am running my GridServer and Nodes on the cloud and </p>
  
  <p>when I want to access the Grid I use:
  <code>http://someip:4444/grid/console</code></p>
  
  <p>When I want to access the node I use:
  <code>http:someip:&lt;nodeport&gt;/wd/hub</code> </p>
  
  <p>I think its a kind of threat as the IPs are publicly accessible. How can I limit that it shouldn't be opened by external users.</p>
  
  <p>Is there any solution for it?</p>
