Security framework for integrated networks

In the last few years extensive efforts have been done to consolidate the manifold network environments. The needed services are integrated in a clearly arranged network and thus, decreasing costs and personnel overhead. Research in network and distributed systems security has provided significant contributions for well-known security problems. However, this is mostly done on the cost of expense, scalability and performance. In this paper, we discuss the limitation of current security mechanisms in heterogeneous networks and present a general-purpose security framework for integrated networks which overcomes with the shortcomings of the present situation.
