Abstract:
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 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.
