过去人们对网络安全问题的研究主要集中在技术方面,而网络安全问题不是单纯依靠技术手段能解决的,安全管理也是解决网络安全问题很重要的手段。因此文章首先给出网络安全问题的一种描述方法,综合技术和管理两方面的内容,采取层次化的设计方法,提出了一种混合的安全模型,为今后研究和实施网络安全系统提供参照。
In the past, people mainly focused on the research of network security issues in terms of technology. However, the problem of network security can not be solved simply by technical means. Security management is also an important means to solve the problem of network security. Therefore, the article first gives a description of the network security issues, comprehensive technology and management of both content, to take a hierarchical design method, a hybrid security model is proposed for the future study and implementation of network security systems provide a reference.
