Disclosed is a method, a device, and/or a system of control over data resource utilization through a security node control policy evaluated in the context of an authorization request. In one embodiment, a method includes receiving an authorization request from a device to utilize a protected resource within a datastore. A control policy extracted from a security node defines an authorized context for the device to utilize the protected resource. The control policy includes a control algorithm comprising one or more conditionals comparing context values to control ranges. Context values are retrieved to form a context dataset. Utilization of the protected resource is authorized when it is determined by the control algorithm that the context dataset conforms to the authorized context. The security node may organize data into a domain structure that includes a unique identifier, an identity element, a content element, and a context element.
