Best way to further secure rails app from?

Question

I am using rails 3.2 and devise 1.5.3.

I added an admin attribute in my model as described in option 2 on the devise wiki How To: Add an Admin Role

I added this in a post controller for force logins:

before_filter :authenticate_user!

I wrote some logic to hide the edit/new links in my views based on whether you're an admin or not.

I feel like there's more I should be doing.. Should I add anything else to new/edit/delete actions to make them more secure? If so, where?

Answer 1

your answer may be working but it is pretty difficult to ensure security in the whole app if you are using some logic to hide the edit/new links in my views and I'm pretty sure no amount of security testing would give you the feeling that maybe you are forgetting about something

for example I someone could log in,,,, (not having admin profile) and go to (in the URL),: /users/edit/3 and start damaging your valuable information....

situation is: Devise only provides authentication,,, but authorization has to be enforced in some other way or else I could be able to do the above things...

for that I would highly recommend CanCan (from rbates ofcourse) which is the one I have tested personally and is PRETTY easy to configure just by reading the docs and examples in github..... hope it helps!
