Research And Implementation Of System Security And Authority Management In High-Resolution Science And Education Service Platform

High-resolution satellite information products science and education Service platform referred to as High resolution of Scientific and Educational service platform is high resolution to Earth observation one of the major projects,the goal is to research institutes,University remote Sensing application research and industry application research.This platform has the remote sensing image data of our country High resolution series satellite,other high resolution satellite data,basic information products and auxiliary data have the function of obtaining,managing and visualizing the query,and it has a transition function in the process of realizing the comprehensive service function of the model system of the Earth Surface System scientific research application.Because the high resolution of Scientific and Educational service platform needs to face a large number of users of remote sensing data every day,different types of users have different data and information product access requirements,so the security of network data access is one of the main problems to be solved.In this paper,the author participates in the design and implementation of the security function module of the platform upgrade and the function of authority management and control.The main work of this paper is as follows:(1)The related theory knowledge and technology of network security and the design idea of current popular network security management mode are studied,which lays the foundation for the design of this research.(2)An in-depth analysis is made on the information security involved in the high resolution science education service platform before the upgrade,this paper mainly studies the access control model and the external access interface based on double recognition,and understands how the system can improve the system's resisting ability through the model,and participates in some design and implementation in the upgraded version of the platform.(3)The existing role-based access control model is improved and optimized,a new role-based access control model is designed,and the validity of the model is validated by experiments.(4)The design of the access control model is applied to the new version of the high resolution of Scientific and Educational service platform,which strengthens the ability of preventing and detecting the network attack.
