网络安全模型及其优化

Network Sevurity Model and Optimization

为了保证计算机网络系统和信息资源的整体安全性,人们建立了网络安全模型,并对其整体安全性进行研究。P2DR和PDRR为常用的两种安全模型。在详细介绍两种网络安全模型的基础上,对PDRR安全模型进行优化,通过漏洞扫描仪等工具对主机等进行风险评估,并提出防护措施,使之更加安全高效。

In order to ensure the overall security of the information resources and the computer network system, people set up a network security model, and to study its overall safety. P2DR and PDRR are two frequently--used security models. Thispaper optimizes the PDRR security model after introduced the two network securitymodels. You can use Vulnerability scanner or some others to do some risk assessments to increase security of the network security models.
