How to provide only Access for ELMAH.axd for Administrator login in web

I have created application and implemented ELMAH logging. In my site there are three types of users.

Admin : can everything (rights to view elamh.axd)

User : can have own rights (can't view elamh.axd)

Guest : only view (can't view elamh.axd)

The above user will be stored in Database.

Probelm:- Now how could i manage protection level for User and Guest to view ELMAH.axd log file?
