[security-dev] Permission and Role

[Shane Bryzak]

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
