网络信息的相关安全技术

The related and safe technique of the network information

各种应用软件均是建立在操作系统提供的系统软件平台上的,所以操作系统平台的安全性是网络信息系统安全的基础。在网络环境中网络系统的安全性依赖于网络中各主机系统的安全性,而主机系统的安全性是由其操作系统的安全性所决定的。安全的概念包括级别和类别两方面,其中,安全级别之间具有可比性,而安全类别中,DOS系统是最脆弱的,而开放源码的UNIX系统安全性最高。因而开放式操作系统是使网络更具安全性的必由之路。

Every kind of application softwares all established on the system software platform provide by the operating system.Therefore the safety of the operate system platform in the the network system depends on the safety of the nast system lohile the safty of the hait system is decided by its controllig system.The safety's concept includes the classes and categories in which all classes can be compared and DOS system is the east safe,VMX is the safest.
