title: Ensuring security of my files at web server
body: <p>I have hosted my website on a shared web-hosting server. However, I am worried about the security of the files that I have kept on the server. Admins of web-hosting service keep on changing the contents of my cron jobs etc. by their own. I am worried if they change my files also some day.</p>
  
  <p>Is there any way to lock my folders on web-server so that no one else can have access to it as we have folder-locker in Windows.</p>
  
  <p>Any other suggestions are also welcomed in this regard.</p>
  
  <p>Thanks !</p>
