Cloud computing is a large-scale distributed computing paradigm. It is a collection of sources in order to enable resource sharing in terms of scalability, managed computing services that are delivered on demand over the network. The traditional Intrusion Detection System is not flexible in providing security in cloud computing because of the distributed structure of cloud computing. This paper surveys the intrusion detection and prevention techniques and possible solutions in Host Based and Network Based Intrusion Detection System. It discusses DDoS attacks in cloud environment. Different Intrusion Detection techniques are also discussed namely anomaly based techniques and signature based techniques. It also surveys different approaches of Intrusion Prevention System.
