R. Van athi, Shenbagalakshmi Gunasekaran · 2012
Computer Networks face a constant struggle against intruders and attackers. Attacks on distributed systems grow stronger and more prevalent each and every day. Intrusion detection methods are a key to control and potentially eradicate attacks on a system. An Intrusion detection system pertains to the methods used to identify an attack on a computer or computer network. In cloud computing environment the applications are user-centric and the customers should be confident about their applications stored in the cloud server. Network Intrusion Detection System (NIDS) plays an important role in providing the network security. They provide a defence layer which monitors the network traffic for pre-defined suspicious activity or pattern. In this paper Snort, Tcpdump and Network Flight Recorder which are the most famous NIDS in cloud system are examined and contrasted.
