25. The network security device of claim 20 , wherein the client module generates a subscribe IF-MAP message that requests a subscription to the authorization information corresponding to the endpoint device, forwards the subscribe IF-MAP message to the intermediate storage device that implements the IF-MAP data model, generates a poll IF-MAP message that requests the authorization information corresponding to the subscription requested by the subscribe IF-MAP message, and forwards the poll IF-MAP message to the intermediate storage device that implements the IF-MAP data model.
20. A network security device comprising: a policy database that stores an import translation policy; and a control unit comprising: an admission module that receives network traffic from an endpoint device; a client module that requests, in response to receiving the network traffic, authorization information from an intermediate storage device in accordance with an Interface for Metadata Access Point (IF-MAP) protocol and receives the authorization information from the intermediate storage device, wherein the intermediate authorization storage device stores the authorization information in accordance with a first IF-MAP authorization data model that confirms to an IF-MAP standard; and a translation module that applies the import translation policy to translate the authorization information stored in accordance the first IF-MAP authorization data model into translated authorization information that complies with a second proprietary authorization data model, wherein the second IF-MAP authorization data model is different from the first proprietary authorization data model, wherein the admission module forwards the network traffic based on the translated authorization information.
