Hi Vinay

If you are already checking your $_SESSION['authtype'] var, to know whether or 
not to display certain links.. then you can just add the same kind of checking 
at the top of any code that should be reserved for a certain level of user.  If 
someone without proper access has hacked the URL then just redirect to your 
login page, or whatever you want to do to the intruders.
