US Patent 9420002 Authorization server access system

Systems and techniques are provided for authorizing restricted action (e.g., data access) requests using a tiered arrangement. A rule set is generated based on a policy received by an authorization server and is transmitted to a broker associated with an enterprise server. A restricted action request is received by an agent associated with the enterprise server and is provided to the broker associated with the enterprise server. The broker analyzes the request in view of the rule set and determines if the restricted action request should be granted or denied. The policy and/or rule set are updated based on activities and/or events within the system and a new rule set is generated based on the updated policy.
