Modeling & analysis of cost effective high availability security architecture for whole of government systems to cater DDoS attack
2014 IEEE International Conference on Computational Intelligence and Computing Research(2014)
摘要
A Distributed Denial of Service (DDoS) attack can inflict a grave toll on revenues. Developing countries like Nepal where the E-government system services are in infancy state; if attack like DDoS occurs the probability of dying out of system itself is more. Citizens may be reluctant in using E-services. To handle such challenges, this paper compares various security architectures for E-government systems and proposes the high availability security architecture suitable for whole of government systems. The model is analyzed for high availability using SHARPE software package. Sensitivity analysis is performed to verify the effectiveness of the model. Its downtime and cost effectiveness is evaluated as well. The proposed architecture is found to be very effective in E-government system where system's availability is a major concern. Software rejuvenation technique is incorporated to ensure the systems and data are readily available and quickly recoverable.
