Abstract

To provide a technique for implementing suitable authentication and / or authorization in a target system including various assets.SOLUTION: An authentication and authorization system is configured to: acquire an authentication and authorization request for requesting authentication and / or authorization for a request from a request source asset to a request destination asset for predetermined processing; analyze the authentication and authorization request to identify at least one of asset statuses indicating target matters of the authentication and / or authorization for the request source asset and the request destination asset, a request level indicating a degree of confirmation required for the authentication and / or authorization in response to the authentication and authorization request, and a relationship between the request source asset and the request destination asset; and determine authentication and authorization means to be used for the authentication and / or authorization in response to the authentication and authorization request, on the basis of the identified at least one of the asset statuses, the request level, and the relationship.SELECTED DRAWING: Figure 1
