Definition
Level of Authorization, or LoA in this support, describes how much access can be granted depending on the confidence level associated with the identity and its context. Lower assurance leads to no access or restricted access, while higher assurance enables access to more sensitive perimeters. It is a way to make authorization proportional to trust.
The Ariovis perspective
Ariovis separates governed entitlements, authentication and runtime authorization. When a decision depends on the user, resource, action and context, it should be made at the moment of use.
