摘要
在分析影响网络安全几个因素的基础上,分别从OSI/ISO七层网络协议和三层网络结构2个角度,讨论了各个层次网络安全存在的风险和问题,给出了解决各层安全问题应该采用的防范措施。结果认为,为保障网络信息安全,既要弄清网络协议本身存在的问题和漏洞,又要深入研究实际组网的客观要求和情况。
Based on the analysis of factors of network safety, risks and problems in each layer of network are discussed separately from the perspectives of OSI/ISO seven layers network protocol and three layer network frame. Precautions are provided for the safety problem in each layer of network. The conclusion is that to keep network information safe, it is necessary to not only figure out the problems and vulnerability of network protocol, but also learn about the real requirements and situations in netting.
