数据库安全机制的探讨与实现

Research and implementation of database security mechanism

数据库技术已经成为计算机技术的基础和核心,数据库中的数据会受到很多方面的攻击,为保护数据库中数据的安全,数据库提供了各级身份验证机制,防止用户非法登录;提供了服务器角色、数据库角色和权限来限制登录用户的操作;提供了数据加密,即使用户获取数据后需要解密才可以正确读取数据;触发器也可以作为辅助手段保护数据安全性。

Database technology is becoming the foundation and core of computer technology. The data in the database will be suffered a lot of attack, in order to protect the safety of the data; database provides all levels of authentication mechanism, to prevent the user from ille- gal loading; provides the server role, database roles and permissions to restrict user login op- eration; provides data encryption, even if the user gets data also need to decrypt that data can be read correctly. Trigger is also can be used as an auxiliary means to protect data security.
