Security insurance of cloud computing services through cross roads of human-immune and intrusion-detection systems

Cloud computing has emerged as a new computer model that aims to provide reliable, customized and dynamic information technology environments oriented towards a better quality of service and availability of infrastructure without much financial burden. However, this advanced paradigm has immediately highlighted a serious security problem whose resolution is a real challenge. This challenge is explained by the importance of using services offered by cloud computing in distributed applications and by the interest to fully take advantage of their strengths. In this paper, we propose a novel intrusion detection system dedicated to the security of cloud computing resources and services. This system takes advantage from: (i) the intrusion detection system paradigm to implement an efficient security system; and (ii) the integration of human immune techniques, i.e. macrophage, B cells, T cells, and natural killer cells. The performed experiments show the high performance of our proposed system in terms of detection of novel attacks as well as of good detection rates and low false ones.
