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 functional requirements to a myriad of possible security services 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 framework is discussed in terms of “variant” security mechanisms 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 function
