Study on Security Protection Technology of Multi-Network Integration

With the wide application of information technology, the network architecture presents heterogeneous characteristic. As different security requirements, how to realize connection and security management of heterogeneous networks has become an inevitable challenge. Accordingly, it is important to study information security technology in the situation of multi-network integration. Based on the technologies of security supervision, physical dependence and network virtualization, this paper discusses the methods of security protection for multi-network integration. Furthermore, strict management regulations are established to improve the multi-network security performance. The above-mentioned methods were expounded and have been applied to a certain multi-network structure. The result indicates that the security protection scheme presented in this paper is effective and feasible.
