Concepts (6)

deny-overrides
Deny-overrides
The deny overrides combining algorithm is intended for those cases where a deny decision should have priority over a permit decision.
permit-overrides
Permit-overrides
The permit overrides combining algorithm is intended for those cases where a permit decision should have priority over a deny decision.
ordered-deny-overrides
Ordered-deny-overrides
The behavior of this algorithm is identical to that of the “Deny-overrides” rule-combining algorithm with one exception. The order in which the collection of rules is evaluated SHALL match the order as listed in the permission.
ordered-permit-overrides
Ordered-permit-overrides
The behavior of this algorithm is identical to that of the “Permit-overrides” rule-combining algorithm with one exception. The order in which the collection of rules is evaluated SHALL match the order as listed in the permission.
deny-unless-permit
Deny-unless-permit
The “Deny-unless-permit” combining algorithm is intended for those cases where a permit decision should have priority over a deny decision, and an “Indeterminate” or “NotApplicable” must never be the result. It is particularly useful at the top level in a policy structure to ensure that a PDP will always return a definite “Permit” or “Deny” result.
permit-unless-deny
Permit-unless-deny
The “Permit-unless-deny” combining algorithm is intended for those cases where a deny decision should have priority over a permit decision, and an “Indeterminate” or “NotApplicable” must never be the result. It is particularly useful at the top level in a policy structure to ensure that a PDP will always return a definite “Permit” or “Deny” result. This algorithm has the following behavior.
