Comparative Study and Analysis of Cloud Intrusion Detection System

Cloud computing provides a framework for supporting end users easily attaching powerful services and applications through Internet. Denial ofService (DoS) attack or Distributed Denial-of-Service (DDoS) are major security issues in cloud environment. The best solution to protect the cloud from these attacks is use of IDS. IDS have become popular cloud security technology to detect cyber attacks in wide variety of networks. In this paper we will discuss comparative study of various existing integrated intrusion detection systems available to secure cloud. The cloud networks have their own characteristics which are the reason for threats to the security in cloud, cloud intrusion detection system is better solution to achieve a higher level of security maintaining its uniqueness. The cloud intrusion detection system is the most widely used technique where the system consists of IDS connected over the network in combination with Apriori, Bayesian, and Classification algorithms. The paper discusses architectures of cloud Intrusion Detection System and techniques to detect them
