摘　　要：随着计算机网络技术的不断发展,处于网络环境中的数据库系统成为极具诱惑力的攻击目标,如何保证数据的保密性、完整性和有效性是个复杂问题。目前数据库管理系统所提供的安全保护措施虽然能够对其安全起一定的保护作用,但仍然存在漏洞。通过分析系统部件出现故障的原因及相关安全技术,基于入侵容忍技术抽象了一种多层数据库安全模型,能够在遭受攻击的情况下保证用户数据库的可用性、完整性和机密性。With the development of the network technology, the database system in the network environment becomes the attacked aim which has much more attraction. How to ensure data confidentiality, integrity, reliability and availability is a complex issue. The security protection measures provided by the current database management system have some loopholes. By analyzing the faults and relative security technology of the system components, a multi-layer database security model based on intrusion-tolerance technique is abstracted, which can ensure usability, integrity and confidentiality of the user＇s database.
