Study And Application Of J2EE Security In Digital Campus

In this new century, the rapid development of information technology which is based on network communication and multi media technology has led to profound transformation in many fields of the society. In face of the opportunities provided .by informationalization and guided by the tide of global digitization, the digital and informational construction in Chinese high schools has been quietly stepping forward.Considering the needs and characteristics of its own development, National University of Defense Technology (NUDT) is steadily carrying out the construction of a digital campus by using J2EE which is the most successful technology with the brightest application prospect in current Large-medium-sized Distributing Applied System. Along with the progression of informationlization of the university, the problem of security is becoming more salient. Therefore, it has been an urgent need to re-analyze the security of the application system and construct a system of security mechanism to cover this whole digital campus.Security is not only a question of technology, but an integration of strategies, technology and management. Centered on this concept, the study and practice of J2EE security has provided the digital campus with whole security strategy and referential security model of the application system as well as the realization of security service. The successful application of these in the project of digital campus caters to the security needs of NUDT digital campus construction.Based on the discussion of related background information and through three parts which are the analysis of J2EE security, the whole digital campus security strategy and referential model together with security service, and the development and secure realization the information system of the Department of Scientific Research in the university, this thesis summarizes the study of the subject and the achievement that has been made and proposes some opinions and thoughts for the further study of the subject in the final part.This thesis has important value in terms of reference and guidance for the security construction of digital campus in NUDT.
