Research On The Model And Application Of User Level Security Audit For E-government Entranet Application

With the extensive construction and application of e-government,the core component of e-government network application system will involve state secrets.There are primary hot issues about how to ensure the security of national secret information and ensure the effective use of government information resources in the process of the application and construction of e-government network.The e-government network users through the interaction process of egovernment network applications to come true the utility e-government information.It has proved that an effective e-government network user behavior security audit is an important means to ensure the utility and security of e-government application information.It has aroused the concern of e-government network application researchers and construction managers about e-government network's model and application research.Through the analysis of the requirements of user security audit in the security standard under the application of e-government network,aiming at the problems in the security audit of user behavior in e-government network application construction,facing the development trend of cloud framework technology for e-government network,combined with e-government network application user behavior security audit platform development practice,based on the theory and method of intelligence analysis,knowledge management,system engineering and software engineering,the thesis puts forward a kind of user behavior security audit driven by user behavior information model and the centralized user behavior security audit platform for cloud service architecture.The main work of this paper are as follows:(1)Based on the analysis of security auditing requirements of information security level protection standard and grading protection standard,this paper puts forward the user behavior security audit of e-government network application in view of the lack of detailed discussion about user's security audit,the general framework of the system;(2)Aiming at the problem that the user behavior attribute description which is not sufficient in the application design of e-government network and leads to the weakness of user behavior security audit function,the user behavior attribute description model and the user behavior attribute description acquisition method are proposed;(3)Based on the comprehensive user behavior attribute information,this paper puts forward a kind of user behavior safety audit analysis from the perspective of constructing a complete user behavior trajectory for the current user behavior security audit.The method of research is carried out;(4)According to the above research results,this paper puts forward a kind of e-government,which is based on the research results of the e-government network application user security audit island,unable or difficult to capture and comprehensively analyze the user's behavior Intranet cloud architecture Based on the user's behavior security audit platform,and its structure and function of a preliminary study;(5)Combine with their own practical work,participating in the design and development of a city e-government network application platform for user behavior security audit platform and verifying the validity and practicability of the user behavior security audit model proposed in this paper.User behavior security audit is an important component of e-government network application and it is also an important means for the security of e-government application information system.This paper puts forward the application of security model for e-government network application,which is of great significance for the theory and practice of security design in e-government network application.
