A Hierarchical Intrusion Detection System for Clouds: Design and Evaluation
Hisham A. Kholidy · International Journal on Cloud Computing Services and Architecture · 2012
Security and availability are critical for cloud environments because their massive amount of resources simplifies several attacks to cloud services.This paper introduces a distributed deployment and a centralized one for our Cloud intrusion detection framework, CIDS-VERT.After describing the architectures and the components of the two deployments it describes the experimental results that confirm that the deployments overcome some limitation of current IDSs to detect host, network and DDoS attacks.Lastly, we discuss the integration and the correlation of the host and network IDSs alerts to build a summarized attack report.
