Subject: RE: Securing CF Apps.
What!?!?!?
I sure hope the application security would say "hey, you don't have
permission to look at that userID's info, so here's a nice fat error
message", long before it every got to querying the database.
That's the whole point of a security system: to control access to resources.
If you merely make it hard to request the resource, but don't actually
control access, you don't have a security system, you've just got a mess.
Cheers,
