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 policy-
aware. 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 speci-
fication 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 environ-
ment. 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.
