Abstract

Denial of service attacks (DoS) don’t necessarily damage data directly, or permanently but intentionally compromise the functionality. Even in an intrusion tolerant system, the resources will be fatigued if the intrusion is long lasting because of compromising iteratively or incrementally. In due course, the system will not provide even the minimum critical functionality. Thus we propose a model to increase the cluster system survivability level by maintaining the essential functionality. In this paper, we present the cluster recovery model with a software rejuvenation methodology, which is applicable in security field and also less expensive. The basic idea is – investigate the consequences for the exact responses in face of attacks and rejuvenate the running software/service, or/and reconfigure it. It shows that the system operates through intrusions and provides continued the critical functions, and gracefully degrades non-critical system functionality in the face of intrusions.
