【摘要】 网络数据库被多用户共享访问,存在着许多安全问题。明确安全隐患的来源及其危害性,并提出针对性的解决方法,是网络数据库安全体系构建的重点。通过分析网络数据库在网络系统层次、操作系统层次、数据库管理系统层次、应用程序层次四个方面存在的安全问题,并分别利用防火墙技术、安全漏洞检测技术、数据库加密技术、视图与存储过程等技术或方法来保障各层次的安全,构建了一个实用性强、可操作性好的基于层次模型的网络数据库安全体系。更多还原

【Abstract】 Shared by multi-users,there must be many security problems in the network database.It is the keystone of building the network databases’ security system for us to make definite the sources and their dangers of potential safety problems,and then propose some specific solutions.By analyzing the security problems that may encounter in the following four hierarchies: network system hierarchy,operation system hierarchy,database administer system hierarchy and application hierarchy,respectively use firewall technology,security vulnerability detection technology,database encryption technology,and view or stored procedure technology,and other technical methods to protect the safety of all levels,and finally construct a practical and maneuverable network database security system based on hierarchical-level models.更多还原
