Designing a multi-layered security algorithms for network intrusion detection systems on virtual machines in the cloud computing

With the emergence of new generation networks and providing new types of services, as cloud computing networks, the need to provide security that are compatible with the performance of these networks lead us to offer an algorithm for using the context of security available in prior networks. In this algorithm, intrusion detection systems(IDS) are activated depending on the service which selected by the user. The packages of each user is related to the network layer and standard protocols and will be selected considering that intrusion detection system. The techniques used in this paper are based on the parallel use of intrusion detection systems on network virtual machines. As objectives of this algorithm, we can point to reducing the computational load in contrast to large number of users and applications. Considering that internet is the context of using these networks, we need to reduce the response time to the user as short as possible.
