Abstract: A method of establishing centralized trust includes, at a policy server having connectivity to a network, establishing a trust relationship with a first enterprise network domain and a second enterprise network domain. One or more criterion from a server in the first enterprise network domain are received by the policy server and a federation relationship is established between at least a portion of the first enterprise network domain and one or more entities in the second enterprise network domain based on the one or more criterion. Based on the federation relationship, the policy server enables the one or more entities in the second enterprise network domain to access the at least a portion of the first enterprise network domain.
