在保证数据库安全性的技术中,访问控制技术是目前应用最广泛、也是最有效的一种技术措施。从分析DAC、MAC和RBAC的特点入手,提出在RBAC模型中增加时间和空间因素,从而加强安全性控制的技术方案,该方案增加了非法用户对数据库系统进行攻击时的难度,可达到有效保护数据库安全的目的。
In the technique of assurance database security, access control technique is most extensively currently to apply and is also a kind of the most valid technique measure. From analysing the characteristics of DAC, MAC and RBAC, puts forward time of increment and space factor in the RBAC model, strengthens the technique project of security control and that project increased an illegal customer to carry on the difficulty which attackstones a hour to the database system, can attain a valid protection database the purpose of security.
