    Abstract: This study addresses the problem of security interoperability in an integrated heterogeneous
database environment. It presents a universal framework of security management model for integrating and
managing security features namely label-based access control of integrated heterogeneous relational legacy
databases. The model is anchored in Rule-Based Algorithm and Global Security Policies, using XML as
integration medium with richer features and above. Validation and implementation of the expedient model
are also provided including the designated-principal benchmarks.
