Academic Management System Security Design And Implementation

With the rapid development of computer technology and the popularization of internet, Education Management System(EMS) based on internet has gained great development. Meanwhile, the security problems in EMS become more and more severe. Therefore, on the basis of the current EMS, the construction of security policy in EMS should be enhanced, and the safe access technology should be further developed to ensure the EMS information security.Focused on the security problems in EMS of Hengshui College of Vocational Technology, on the basis of the analysis on database encryption technology, this thesis firstly analyzes the threats that EMS is confronted with, and then proposes the database security schemes which can protect the system, This thesis presents the security schemes on access control, database encryption, and firewalls and intrusion detection, etc. By analyzing the current database encrypt techniques, it presents the four levels key management which supports cipher text retrieval and then presents the algorithms on sub-secret key based encryption. This paper also discusses database encryption module. This module is designed and realized by the way of confusion and data encryption algorithm in EMS. In the end, the database encrypt function in EMS is tested, and the results show that it can effectively protect the sensitive information in EMS and thus enhance their security levels. The proposed schemes are able to fundamentally ensure the EMS database secure, controllable and manageable, which guarantees the college EMS runs effectively and successfully.
