Therefore, in such a great threat to security in the background, how to take measures to protect the network database against security threats become very important.网络上的非法用户通常都是直接通过网络系统来实现入侵网络数据库，以此来达到攻击网络数据库的目的，所以网络数据库的安全性基本决定于网络系统的安全情况。
一般情况下，我们将网络数据库面临的安全威胁归纳为以下几个方面：（1）因用户操作不当而导致的网络数据库数据错误；（2）非法访问非权限范围内的数据信息：（3）攻击数据库的正常访问；（4）非法窃取或篡改连接中数据库内的数据资源信息。
The illegal Internet users are usually directly through network system to realize network intrusion database, in order to achieve the purpose of attacking network database, so the security of network database of basic depends on the network system security. In general, we will be the networkdatabase security threats to reduce the following respects: ( 1) improper operation by the user in network database data error; ( 2) the illegal access to non purview data information: ( 3 ) to attack normal database access; ( 4) theft or tampering with the connection the data within the database resource information.3、网络数据库安全技术方案探讨In 3, the network database security technology discussion在开放的网络环境中，网络数据库是非常容易遭受到各种安全威胁的，所以我们必须要采取实际有效的技术方案来不断提高网络数据库自身的安全性，以保证数据的完整性和一致性。
一般来说，网络数据库的安全问题可归结为保证数据库中各种对象存取权的合法性和数据库内容本身的安全两个方面，具体安全技术方案有如下几方面：In the open network environment, network database is very susceptible to various security threats, so we must take practical and effective technical solutions to improve the security of network database, in order to ensure data integrity and consistency. In general, the security of network database can be reduced to ensure the database of various object access rights and the legitimacy of the contents of the database itself security two respects, specific security technology scheme are as follows:3.1 用户身份认证3.1 user authentication由于计算机网络环境是一个面向多用户的开放式环境，所以对每一个网络数据库访问用户都必须要进行统一的身份认证，这也是防止网络数据库被用户非法访问的一个最有效的手段。
