SQL Server 2012审计报告生成

2023年6月28日 179次阅读

试图确定一台服务器输出的审计文件是否可以在该服务器上没有CONTROL SERVER访问权的情况下读取.
MSDN docs表明这是可能的：

Even when the Database Engine is writing to a file, other Windows
users can read the audit file if they have permission. The Database
Engine does not take an exclusive lock that prevents read operations.

并且：

We recommend that you generate audit reports from a separate instance
of SQL Server, such as an instance of SQL Server Express, to which
only Audit Administrators or Audit Readers have access. By using a
separate instance of the Database Engine for reporting, you can help
prevent unauthorized users from obtaining access to the audit record.

总之,我可以这样做吗？

[澄清]
q的关键部分是,您是否可以使用来自单独数据库的sys.fn_get_audit_file访问该文件,而无需在创建审计信息的数据库上拥有管理员访问权限.这样我们就可以让具有DB管理员访问权限的DBA独立于文件系统访问的审计读者.对不起,最初没有说清楚.

就您的答案而言,此查询是否可以从不相关的SQL Mgmt Studio / DB运行,由不是原DB上的DBA的人运行？

SELECT 
    event_time, action_id, session_id, object_id, class_type, 
    database_principal_name, database_name, object_name, statement
FROM 
    sys.fn_get_audit_file('\\Temp\Audit\*',NULL,NULL);

最佳答案 确实,这很有效.

USE [master]
GO

CREATE SERVER AUDIT [SQL2012-Audit-20121214-Demo]
TO FILE 
(   FILEPATH = N'\\Temp\Audit'
    ,MAXSIZE = 2 MB
    ,MAX_FILES = 32
    ,RESERVE_DISK_SPACE = OFF
) WITH (QUEUE_DELAY = 2000,ON_FAILURE = CONTINUE)
GO

ALTER SERVER AUDIT [SQL2012-Audit-20121214-Demo] WITH (STATE = ON);

USE [Performance]
GO

CREATE DATABASE AUDIT SPECIFICATION [SQL2012-DBAudit-20121214-Demo]
FOR SERVER AUDIT [SQL2012-Audit-20121214-Demo]
ADD (SELECT,INSERT,DELETE,UPDATE,EXECUTE ON DATABASE::[Performance] BY [dbo])
WITH (STATE = ON);
GO

在服务器审计和数据库审计到位并激活后,立即创建第一个审计文件,并且无法删除它,因为Windows声明该文件正在使用中.

但是,从文件中选择始终有效.这是“工作量”,其活动据称是由审计设置捕获的：

SELECT * INTO partition_stats_4 FROM Performance.sys.dm_db_partition_stats
SELECT * INTO partition_stats_3 FROM Performance.sys.dm_db_partition_stats
SELECT * INTO partition_stats_2 FROM Performance.sys.dm_db_partition_stats
SELECT * INTO partition_stats_1 FROM Performance.sys.dm_db_partition_stats
SELECT * INTO partition_stats   FROM Performance.sys.dm_db_partition_stats

DELETE FROM partition_stats
DELETE FROM partition_stats_1
DELETE FROM partition_stats_2
DELETE FROM partition_stats_3
DELETE FROM partition_stats_4

DROP TABLE partition_stats_4
DROP TABLE partition_stats_3
DROP TABLE partition_stats_2
DROP TABLE partition_stats_1
DROP TABLE partition_stats

这是结果：

SELECT 
    event_time, action_id, session_id, object_id, class_type, 
    database_principal_name, database_name, object_name, statement
FROM 
    sys.fn_get_audit_file('\\Temp\Audit\*',NULL,NULL);

 

顺便说一句,这与服务器端跟踪文件完全相同.我们一直在运行跟踪,文件是“可查询的”,没有任何问题.

快乐的审核！
