Security Based Performance Issues in Agent-based Web Services Integrating Legacy Information Systems

Many closed internal information systems (IS) must not concern much about its security. But, nowadays, mostly due to globalization and dynamic world, business demands integration of several legacy ISs into new one. The new IS must improve its security compared to legacy ISs, because they work in the heterogeneous environment, and need to be opened. Adding security will decrease the new IS performance, but business wants to retain or even improve it. In this paper, we simulate this issue and we create a baseline of performance data that can be used to predict IS response time, for various numbers of requests, request size and implementing security as a necessary issue for new distributed IS.
