Abstract
Authorizing information flows between devices of a data processing system is provided. In one illustrative embodiment, an information flow request is received from a first device to authorize an information flow from the first device to a second device. The information flow request includes an identifier of the second device. Based on an identifier of the first device and the second device, security information identifying an authorization level of the first device and second device is retrieved. A sensitivity of an information object that is to be transferred in the information flow is determined and the information flow is authorized or denied based only on the sensitivity of the information object and the authorization level of the first and second devices irregardless of the particular action being performed on the information object as part of the information flow.
