Evaluation vs Search
Authorization evaluation questions ask "Can subject
do action
to resource
(with context
)?", e.g.
- Can Sally (
subject
) withdraw (action
) $5,000 (context
) from account 058201 (resource
)?
The response to this is allow or deny.
Authorization search questions ask which values of an unknown generate an allow or deny decision, e.g.:
- Unknown Actions: What actions can Javier do on an escalated ticket?
- Unknown Context: During what hours can badge #2541 access the store room?
- Unknown Subject: Who is allowed to approve payments over $10,000?
- Unknown Resource: Whose salaries can a Director see?
The response to this is a set of filtered application data.
