摘　　要：审计作为事后追踪的凭证,在安全要求级别较高的系统中扮演着重要的角色。为了解决审计信息冗余、格式复杂、影响性能等问题,提出了基于中心节点的SQL Server数据库审计系统,提供用户有选择地选取审计跟踪的对象与内容,并将审计数据按分区表方式存放于数据中心,再通过报表服务展现给用户,提高了审计数据的安全性。实验证明,降低了对数据库性能的影响,方便审计数据的管理,而且简化了用户对审计数据的查询与分析。As a way to provide evidence for later tracking,audit plays an important role in systems that require high security.In order to resolve such problems as audit information redundancy,file format complexity and performance deterioration,the author proposes a SQL Server database audit system based on central nodes,which offers users audit trace events selection for object and content.Besides,the system stores audit data in the central server using partition table and then presents them to user in reporting service form.Experiment shows that the system not only ensures the security of audit records,but also reduces the performance impact on application databases.What＇s more,it eases the management and facilitates the query and statistical analysis of audit data.
