Collaborative intrusion detection as a service in cloud computing environment

With the growing trends of cloud computing, the security issues in this area are growing at the same speed as its development. Some malicious intruders and other malware activities tend to find the inner vulnerabilities and spare no effort to control the administration or conduct the pure break-down service with curiosity or on purpose. Traditional defense systems such as firewall, intrusion detection and malware code system are still utilized in nowadays network scenes, but they may not support enough in cloud computing environment with old-fashioned architectures. Here we focus on intrusion detection system (IDS) to defend against intruders and other attacks. In this paper, we proposed a collaborative intrusion detection service and our goal is to make use of the state-of-the-art computing framework in cloud environment and to provide a rounded IDS service for both cloud providers and cloud tenants, while the collaborative architecture will help to respond to the attacks promptly. We set up our system prototype and discuss the empirical results on the preference. The experimental results demonstrate that our system does enhance the security when some network-based attacks happen and ensure that both cloud service providers and tenants are protected with satisfaction.
