[security-dev] Permission and Role

[Rahul Mahindrakar]

Is it possible To aggregate permissions under roles.

This makes it easier To grant roles To A user and thereby A large set OF permissions.

Hi Rahul,

They are fundamentally two very different things.  A role is typically used to define a set of users for which specific privileges are to be assigned, while a permission is used to control access to application resources or services.  A permission check can actually use the user's roles to determine whether the user has the necessary privilege to perform an action.  Here's a couple of pseudo-code examples to make this a little clearer:


1. Restricting access to a method based on the user's role:

@RolesAllowed("admin")
public void doProtectedOperation() {
   ...
}

2. Restricting access to a method to users with permission to cancel a specific "order":

public void cancelOrder(@HasPermission("cancel") Order order) {
   ...
}

Hope that helps!

Shane
