Distributed and Cooperative firewall/controller in cloud environments

In recent years, the work environments such as the cloud and Internet of Things (IoT) have become more sophisticated, and for proof, the access control network has become very important. To adapt to changing environments, in cloud computing, access network verification is an important requirement for researchers to integrate traditional verification using virtual firewalls. Virtual firewall is an effective static verification method, but existing problems at the access network in cloud environments remain unresolved. In this paper, we propose a cooperative firewall framework that applies a model in a complex topology like cloud computing to enable a verification access network. The proposed framework consists of the design of a cooperative firewall in cloud computing using a new partition for the topology and a sequential finite state machine (Se-FSM ) representing the migration rules between existing and distributed firewalls. The evaluation of the proposed framework is performed using the NeSSi2 tool, where the results show that the proposed method not only is promising in terms of delay and blocking rate but also can detect the DDoS attacks.
