摘要
社会网络的发展为用户提供了新的商业机会和沟通渠道,但同时也引入了新的安全问题。网络攻击的复杂性、多变性,使得如何利用最低的网络开销提供最优的服务安全成为当前的研究热点之一。针对社会网络中的信息安全问题,引入"柔性退化"的概念,以G-N和分角色社区挖掘算法为基础提供不同的安全保护措施,建立了一种基于角色划分的多层次柔性抗攻击社会网络防护体系。通过研究表明,分角色安全保护策略的效果远远优于基于G-N的单一保护策略,它能够使用较低的网络开销保持灵活、持久、稳定的抗攻击效果。
The development of social network provides users with new business opportunities, but also imports new security issues. The complexity, variability of network attacks makes it a research spot to use the least charge to provide the best service security. This paper in terms of the information security problem, introduced the concept of ＂flexible deterioration＂, offered users with different protection strategy according to the result of G-N and role assorted（R-A） community discovery algorithm, and constructed a set of multi-level flexible anti-attack social network protection system. Experimental results show that the results of role assorted security tactics is much better that the single protection based on G-N, it is able to flexibly, steadily resist the network attacks in low price.
