Abstract

Internet becomes more and more popular, and most companies and institutes use web services as a fundamental tools to promote their business. As results, Internet and web services become core infrastructure for a business and become more and more important, but attacks against web services increase as the popularity of web services grows. Therefore, there are increasing needs of undisturbed web services despite of attacks. In this paper, we proposed adaptation policies for a web-server intrusion tolerant system. Our proposed adaptation policies allow the system to provide continuous web services using various techniques, such as intrusion tolerant types, replication degree, server allocation mechanism, adaptive access control method and so on.
