摘要: 对云服务所涉及的相关要素进行抽象,提取其生态防御特性,并根据人工免疫系统中的病毒传播理论,建立一种具有主动免疫隔离功能的SEIR类传播模型。该模型可以主动采取预防措施,使其免受病毒入侵。根据不同的网络危险程度,采取不同的隔离策略,从而最大程度地保证云环境中服务行为的安全。仿真结果证明,该模型具有较高的自适应性、鲁棒性、入侵容忍和自愈能力,能有效控制云计算网络中危险的传播。

Abstract: This paper extracts related factors involved by services in cloud environment and proposes the character of ecological defense of cloud computing networks. An analogous SEIR propagation model with active immunization and isolation function is established by using virus propagation theory in biological immune system. The model aims at taking preventive measures actively before risk behaviors emerge in cloud computing networks and adopting a different isolation strategy with the status of current network to guarantee the security of services in cloud environment as possible. Simulation results show that the model has self-adaptivity, robustness, intrusion-tolerance and self-healing, and it is an effective method of controlling risks emerge in cloud environment.
