摘要:

多接入边缘计算(multi-access edge computing,MEC)部署在网络边缘,在实现移动网络中高效、快速的数据处理的同时,还承担着重要的安全功能,这使得MEC成为攻击者的主要目标。因此,MEC节点将面临巨大的安全风险,如何准确地评估、量化MEC安全能力是迫切需要解决的课题。为了准确地评估、量化MEC安全能力,结合MEC安全风险提出了MEC安全评估体系,该评估体系选取的评估指标较为全面地反映了MEC 的基本特性,体现了其完整的安全能力。基于此评估体系,利用层次分析法(analytic hierarchy process,AHP)和模糊评价设计了MEC安全评估方法,创新性地提出了MEC漏洞评分系统,并参考该系统的结果给出指标评价,最终计算出MEC安全能力量化值。实例结果证明了方法的有效性。

Abstract:

Multi-access edge computing (MEC) is deployed at the edge of the network, enabling efficient and fast data processing in mobile networks, while also undertaking important security functions, making MEC a prime target for attackers.Therefore, MEC nodes will face huge security risks.How to accurately evaluate and quantify MEC security capabilities is an urgent issue to be solved.For accurately evaluating and quantifying MEC security capabilities, the MEC safety assessment system was proposed in combination with MEC safety risks.The assessment indicators selected in the assessment system comprehensively reflect the basic characteristics of MEC and its complete safety capability.Based on this evaluation system, the MEC security evaluation method was designed by using the analytic hierarchy process (AHP) and fuzzy evaluation, the MEC vulnerability scoring system was creatively proposed, and the evaluation indicators were provided based on the results of MEC vulnerability scoring system, the MEC security capability quantification value was finally calculated.The experimental result proves the effectiveness of the method.

Key words: 5G MEC, security assessment system, vulnerability scoring system, AHP, fuzzy evaluation
