Abstract
Rapid growth of resources and escalating cost of infrastructure is leading organizations to adopt cloud computing. Cloud computing provides high performance, efficient utilization, and on-demand availability of resources. In modern days, with the increasing popularity of cloud computing, security in cloud has become a significant issue. As ‘prevention is better than cure’, detecting and blocking an intrusion is better than responding to an intrusion after a system has been compromised. With the increasing amount of network throughput and security threat, the study of intrusion detection systems (IDSs) has received a lot of attention throughout the computer science field. Though there is a number of existing literatures to IDS issues, in this paper, we attempt to give a more elaborate survey of prior comprehensive analysis.
