Design And Implementation Of Information Security Level Protection Management System

Classified protection of information security is a kind of work to protect information and information carrier according to the importance level of information system.It is a common means to evaluate the security classified and importance of information system.An important part of this work is that the evaluation institution issues the Classified protection report according to the national standards and the system data of the tested unit.Due to various reasons,the informatization classified of the evaluation institution in China is relatively low at present.In order to improve the work efficiency and report accuracy of the evaluation engineer,improve the level of information management,develop the management system based on MySQL database and Java programming language,which can realize the informatization of classified protection of information work,so that users can automatically generate reports when they collect data into the management system,manage the classified protection work uniformly,and realize the data-based evaluation process.First of all,this dissertation analyzes the research background,research significance and the status situation of classified protection all of the world.Then it analyzes the requirements of the evaluation management system of the classified protection,plans the construction principles of the management system,establishes the technical roadmap of the management system and carries out the database selection,clarifies the evaluation process of the classified protection,and designs the system functions and the use processes according to the evaluation process.Furthermore,the architecture of the management system is designed,and the module design,function structure,menu design,flow design,data structure and processing logic diagram of the management system are proposed.In order to calculate the evaluation score of information system classified protection,the weight of evaluation and financial industry classified protection are established,and Bayesian formula is used for accuracy deduction.Then we use the Java programming language to realize all kinds of functions of the management system,and create the database tables of corresponding functions in the MySQL database.According to the data structure and processing method of the management system,we establish the application relationship between the these,realize the management evaluation process and generate the classified protection report.Finally,the usability test is carried out according to the planned deployment mode.The result shows that the management system can satisfy assessment workers to write reports in their work,and meet the design requirements.The management system improves the accuracy and increases the level of informatization for organization.
