title: Restricting MySQL connections from localhost to improve security
body: <p>I heard that anyone that knows my MySQL Username and Password can access it, Even if it's listening only to <em>localhost</em>.</p>
  
  <p>Supposing my info is as following:</p>
  
  <pre><code>USER: root
  PASS: 123456
  Host: LOCALHOST (only)
  </code></pre>
  
  <p>How is it possible that anyone out there (local) can access it?</p>
