Traditional Host based Intrusion Detection Systems’ Challenges in Cloud Computing

Cloud computing is one of the hottest topics in IT today. It can help enterprises improve the creation and delivery of IT solutions by allowing them to access services more flexibly andcost-effectively. Security concerns in the cloud environment are the main obstacles in cloud adoption. As clouds are distributedin nature, it becomes an easy target for the intruders to exploit the vulnerabilities of the network. Intrusion Detection Systemsare one of the key components for securing computing infrastructures. But there are some issues in applying traditional intrusion detection systems on the cloud. This paper discusseseach of the three cloud models, their security risks and covers the study of intrusion detection system implemented in cloud environment for dealing with various security issues related to cloud, and offers solutions for it.
