Network Intrusion Detection and Monitoring in Cloud Based Systems

In recent times there has been a shift towards Cloud based systems for varieties of applications. But, security concerns have always been a challenge for its widespread acceptance. Some of the major challenges relate to data security, deployment of applications, and security of infrastructural elements. In this paper, we have dealt with one of the important security issues, namely, network intrusion detection, in order to protect cloud infrastructure from malicious users. Our work involves continuous tracking of communication among virtual machines and analyse the packets transmitted over the network for possible intrusive attempts. We have developed appropriate mechanism to monitor the network and measure the sensitivity of certain network ports used for data transmission.
