Modeling and Analysis of High availability Security Architecture for Whole of Government Systems

Failure in complex software or network based information server causes various problems. Recently, security is treated not only to prevent from intrusion but also as a Quality of Service (QoS) attribute. Software failure arises from random uncovering of faults during execution of successful inputs. We cannot predict all future intrusion and faults. To handle new type of attack based on application layer, Semi Markov Model is used to analyze & quantify the security attributes of the system. In developing countries, e-government systems are in its infancy state, if attacks like DDoS occur citizens may be reluctant in using E-services. This paper compares various security architectures for whole of government systems and proposes the optimal solution. The model is analyzed for high availability using SHARPE software package .It focuses on impact rather than specific attack procedure.
