Policy Management for Networked Systems and Applications

In this paper, we present a novel policy middleware architecture for managing IT systems and applications that span multiple networks and administrative domains. The proposed policy middleware provides a standard infrastructure for the creation, storage, distribution, and execution of policies, and helps in reducing the cost of making IT systems policyaware. In particular, we focus on three aspects of the proposed policy middleware that help in making the middleware fully general: (1) a platform-neutral and extensible specification of policies; (2) the local ratification of policies, which lets system administrators accept, reject, or flag an incoming policy; and (3) the transformation of policies, which allows system administrators to transform incoming policies to match their local environment. We present our experience in building an application on the proposed middleware to audit the configuration of a storage area network. We also present performance results from a prototype and show that our policy middleware design can scale to handle a large number of policies.
