A Method for Constructing Heterogeneous Entities Pool in NFV Security Architecture Based on Mimic Defense

The characteristics of resource sharing and centralized deployment of network function virtualization (NFV) make the physical boundary under the traditional closed management mode disappear, bringing many new security threats to the network. To improve the security of the NFV network, this paper proposes a network function virtualization security architecture based on mimic defense. At the same time, to ensure the differences between heterogeneous entities, a genetic algorithm-based heterogeneous entities pool construction method is proposed. Simulation results show that this method can effectively guarantee the difference between heterogeneous entities and increase the difficulty of attackers.
