A Survey on Cloud Based Intrusion Detection System
P. Praveen Kumar, K. Bhaskar Naik · 2013
Cloud Computing is becoming popular day by day as many enterprise applications and data are moving into cloud based platforms. Because of the distributed nature, cloud computing environments are aim for intruders looking for possible vulnerabilities to exploit. However, with the increasing use of cloud computing, security issues are came out on a growing scale. It is needful to solve these security issues to contribute to the wider applications of cloud computing. Security is an important issue in cloud computing environment. Therefore, some Intrusion Detection Systems (IDSs) needed in Cloud computing system for protecting each virtual machine against intruders. There is a trade-off between the system performance and security levels of Intrusion Detection Systems. If the IDS provide stronger security services using more rules or patterns, then it needs much more computational resources in directly proportion to the strength of security. Another difficulty in Cloud Computing is that, it is not easy to analyze extensive amount of logs by system administrators. The main objective of the paper is to propose a model that makes Cloud Computing System to achieve both effectiveness of using the system resources and capability of the security service.
