摘要
En 中文
Cloud computing has become the most needed technology for the IT industry. Impersonation attacks are among the most dangerous threats that Clouds face. In this paper, we present an approach to detect masquerade attacks in Clouds. The efficient detection of these attacks should correlate user behaviors in distinct environments and also should apply to several deployment models. We present and evaluate three approaches to detect Impersonation and masquerade attacks. The first approach analyzes sequences of correlated system calls from the VMs operating systems, while the second analyzes the NetFlow data from the network environment. The third approach integrates these two approaches by using a neural network that will produce better detections than any of the first two approaches. To simplify the testing and the evaluation of the three methods, the Cloud Intrusion Detection Dataset (CIDD) is used as a source for cloud audits data. The evaluation has considered alternative deployment models through our two intrusion detection frameworks, CIDS and CIDS-VIRT. The paper also shows that the proposed detection approaches are more accurate and outperform the SWAD-MMD, a recent masquerade detection framework that works in the cloud computing systems. Furthermore, the paper details our experimental results and evaluates the computational performance and the detection accuracy of these approaches. (C) 2020 Elsevier B.V. All rights reserved.
