摘要
文章首先给出了多个TMN通过X接口互连时面临的安全威胁,进而提出了TMN X接口安全管理的需求,在此基础上提出了两类Inter-TMN安全管理的模型:联合管理模型和协同管理模型。通过引入安全前端作为TMN安全网关,文章的最后给出了基于联合管理模型的实现原型。
This paper examines the issue of providing security for the interaction between TMNs over the TMN X -interface. Based on OSI security architecture and ITU- T TMN Recommendations, threats to TMN are reviewed, which, in particular, is followed by a survey of inter - TMN security requirements. Two major models implementing inter - TMN security management architecture are presented in details, which are Joint Management Model and Co - operative Management Model. Finally, we introduce security front - ending devices as TMN - gateway to implement a prototype based on Joint Management Model.
