Federated systems are an emerging paradigm for
information sharing and integration. Such systems
require access management policies that not only
protect user privacy and resource security but also
allow scalable and seamless interoperation. Current
solutions to distributed access control generally
fail to simultaneously address both dimensions of the
problem. This book describes the design of a policy
engineering framework, called X-FEDERATE, for
specification and enforcement of access management
policies in federated systems. The framework has been
designed from the perspectives of both security
management and software engineering to not only allow
specification of requirements for federated
access management but also allow development of
standardized policy definitions and constructs that
facilitate policy deployment and enforcement in a
federated system. The framework comprises of an
access control language specification that is an
extension of the well-accepted Role Based Access
Control (RBAC) standard. The language extends RBAC to
incorporate various essential features for federated
access management.
