Abstract

The proliferation of the Internet in recent years has radically altered the landscape of network security. Despite continuing attempts by organisations to secure corporate networks, the high rate of successful network attacks have led to significant financial losses. This paper concerns the protection of virtual networks against network attack. The limitations of current security tools are outlined. Based on this analysis, a Distributed Cooperative Multi-layer Security Architecture (DCMSA) for virtual networks is proposed. The structure of the DCMSA is detailed and the advantages of this architecture are discussed. In short, the DCMSA provides distributed security enforcement combined with centralised management. Further, it uses the synergy of different security tools working together and multiple layers of defence to provide enhanced protection.
