A Security Mechanism For SaaS Cloud Service Model Using Dynamic Network Strategy Plan

Abstract

Cloud computing is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly. Now the organizations are trying to migrate into a cloud system, so the cloud system should be secure enough to deals with the organizational services. The SaaS model is easily vulnerable to attacks. The main cause for the attack is the static network configurations. These static network configuration may open the attackers to study the weakness of the network and this will help the attacker to launch the attack. The cloud models mainly suffer DoS attack. The main reason behind is the static network configuration. So the paper suggests a security mechanism to protect SaaS model from DoS attack. For this a dynamic network strategy plan is used. In dynamic strategy plan, the network configurations can be done dynamically. To avoid DoS attack, we are changing the IP address of the network host using NOX controller algorithm. It is very difficult to implement I traditional network, so Software defined networking is adopted.
