在对物联网安全进行研究的过程中,对于不同安全敏感度应用,通常是人为判断其所属的安全等级域。针对该问题,以等级划分为基础,提出一个物联网安全模型,利用该模型分析某一物联网应用的拓扑结构,预测其攻击来源与类型并判定其所属的安全等级域,从而对该应用进行合适的安全技术配置。将该模型用于某大学的智慧校园系统中,实践结果证明,其有利于学校更好地发展智慧校园应用,建立更加安全、稳定的智慧校园系统。
Different applications have different security sensitivities,which are determined by subjective judgment in the process of security research on Internet of Things(IOT).This paper presents a Security Model of IOT Based on Hierarchy(BHSM-IOT),which can be used to analyze the topology structure,predict the attack source and attack type and determine the application level of security domain,so that appropriate safety technical configuration can be made.The model is applied in a wisdom campus system of a university,and result proves that it is helpful for the managers to construct a more safe and stability system for the students and teachers with the model.
