A Survey on Various Intrusion Detection System Tools and Methods in Cloud Computing

Cloud Computing (CC) depends on sharing of resources to achieve coherence and economies of scale similar to a public utility. An Intrusion Detection System (IDS) is a network based security technology built for detecting vulnerability exploits against a target application or computer. Computational Intelligence (CI) refers to a set of nature-inspired computational methodologies and approaches to address complex real world problems; solutions to these problems may not be possible through mathematical reasoning. The objective of the paper is to account for cloud intrusions, various classifications of IDS along with CI in cloud. The paper discusses the inter-link between the intrusion detection methods and computational intelligence in a cloud environment. The survey reveals a detailed classification of IDS through various parametric techniques and the purpose of the classification is to provide IDS in a nutshell by using CI methodology.
