Towards a new approach for adaptive security management in new generation virtual private networks

Once a company is located on several sites, the communication between these sites would be critical for its activity, regardless of its size. VPN technology allows the connection between these different sites, while giving the user the benefit of the security. New Generation VPN technologies allow to create multiple virtual tunnels between various devices in a fast, automatic and dynamic manner. However, existing technologies represent limitations of reliability, which means, the security policy deployed in a domain or a cloud, will be applied on all sorts of traffic whatever its type. This paper proposes a new model of adaptive security that we have called Smart Security Management for New Generation VPN. This model allows to generate security policies in an automatic, intelligent and adapted way to the performances of the transported applications and the network status. That is, if the network is overloaded and the flow to be transported is of real-time type, then generate a policy of medium, low security level or even not secure if the organization allows it in the contract.
