Toward quality of security service in a resource management system benefit function

Enforcement of a high-level statement of security policy may be difficult to discern when mapped through func-tional requirements to a myriad of possible security ser-vices and mechanisms in a highly complex, networked environment. A method for articulating network security functional requirements, and their fulfillment, is presented. Using this method, security in a quality of service frame-work is discussed in terms of “variant ” security mecha-nisms and dynamic security policies. For illustration, it is shown how this method can be used to represent Quality of Security Service (QoSS) in a network scheduler benefit function1.
