Dependability Evaluation of Service-oriented Information System Using Computer Simulation and Post-processing Results

In times of known hacking techniques as well as malicious software ubiquity, mostly commercialized information systems are seriously threaten. For this reason nowadays network security and dependable operation has become a major priority for design and implementation. Looking for powerful means network engineers started to often use computer simulation technique as a way for better understanding and development of complex computer systems. Therefore, plenitude of specialized development initiatives appeared in last few years. Currently network simulators are tools useful not only for creating new and better protocols, but also become money savers. By extending their functionalities e.g. post-processing capabilities for evaluating security and dependability metrics they turn out to be a fundamental state of the art network management platforms. This paper presents the information system, proposes metrics definitions, and describes the procedure of their evaluation using a simulator and a post-processing module.
