基于安全系数的网络安全防范措施

分析了计算机网络的主要应用领域并讨论了计算机网络主要的安全性问题,从计算机网络应用领域（工作、学习、娱乐）的角度考虑,通过收集大量数据,在既能保证网络安全,又能提高网络速度的原则之下,以银行职员王先生、惠州学院徐同学和退休干部林先生为例,采用安全系数函数得到他们的计算机网络安全系数分别为：0.81、0.64、0.40,与传统安全措施不同的是,通过分析,根据不同的安全需求建议选择最适合用户的安全防范措施。

Measures based on the Safety Factors of the Network Security

This paper analyzes the main application areas of computer networks and discuss the main security issues in the computer network,from the computer network applications＇（work,study,entertainment） point of view,Under the principle that we can not only guarantee the network security but also improve the speed of the network,we take the example of three people,the bank staff,Mr.Wang,a student of Huizhou College,Mr Xu,and a retired officer,Mr.Lin,and collect large amounts of data about them.We use the factor of safety function to get the safety factor results of these three people.Their safety factors of the computer network were： 0.81,0.64,0.40,by our analysis and according to different security needs,we offer some suggestions to choose the most suitable safety precautions for users.
