The Research of Risk Evaluation Method of Modularization and Hiberarchy of Information Security
信息安全风险模块化层次评估方法研究

Information system has been used in every walk of life and its security has nearly been noticed.The risk e- valuation which can analyze the current status and potential risk of information system provide gist and direction for lat- er security programming,moreover it is an important and indispensable for programming,building and maintaining se- curity framework of information system,so it is indispensable.We use system clustering method to build risk evalua- tion method of modularization and hiberarchy based on the strong function modularization of information system.It breaks up the system into seven modules:manage module,core module,distribution layer module,sever module,mar- gin distribution module,Internet module and outer circumstance module.In this article,we introduce detailedly the modularization model,the clustering method and the evolution process.
