Analysis of dynamic service oriented systems for security related problems detection

The paper presents an approach to solve some problems arising in the management process of IT security. Our motivation of this research is to study in every detail the context of service oriented systems, which can be defined as considerable heterogeneous, dynamic and flexible configuration of the hardware and software system resources. The fundamental difference between security management systems with traditional centralized and monolithic architecture and service oriented systems is discussed. We propose a multilayered-reference model for service-oriented systems aimed predominantly at principal objectives related to IT based systems security working in dynamic environments. Likewise, considered are some dedicated to service-oriented environments key assumptions of a multi-agent system design with the aim at security analysis. The last part of the paper presents briefly the results of our analysis of IT security aspects, performed on the comparison basis of correlation between the events observed at the low and at high layers of our reference model.
