Research And Development Of Engineering Supervision Information System With High Security

Surpervision information management system is a construction based onmanagement, information and system, which is a human-machine system capable ofinformation acquisition, transmission, storage, processing, maintenance and use.Information security is the most essential concern in information age, especially innetwork communication. This thesis elaborates on the research and development ofthe production management information system of marine carriage engineeringsurpervision company of Guangzhou port by employing computer network technology,software engineering criterion and communication security technology, which aims todevelop a reliable and convenient system that fits the production management of thecompany. The system distinguishes itself with two features besides improving themanagement efficiency in a more scientific way. Firstly, the system makes use ofadvanced network security technology SSL VPN and OTP to enhance the security ofthe system; secondly, the system adopts more reasonable authority division, users ofdifferent levels having varied access rights.Chapter 1 describes the status of the information system. Chapter 2 studies thebasic theories. Chapter 3 makes an analysis on the syf the system as well as databasedesign. Chapter 4 gives an introduction of the whole realization ostem with a detailedanalysis on some core modules of the system and tells the design and realization ofsecurity strategies used in the system. Finally, it summarizes the key technology andcore problems during the process of system development together with a discussionon further improvement of the system.
