四、管理特权审计：
****************************************************************************************
----------------------------------------------------------------------------------------
管理特权审计包括监视和记录需要一个指定系统特权的SQL语句的执行；可以审计任意一个系统特权。

-- 4.1 启用审计特权

SQL> audit create any table;

Audit succeeded

-- 4.2 审计具体用户

/*
环境准备：

create user win identified by password
quota 100m on users;

grant create session, create table to win;

*/

--步骤1：检查已经启用特权审计

SQL> select user_name, privilege, success, failure from dba_priv_audit_opts ;

USER_NAME PRIVILEGE SUCCESS FAILURE
------------------------------ ---------------------------------------- ---------- ----------

--步骤2：启用特权审计
SQL> audit select any table by scott by access;

Audit succeeded

--步骤3：检查已经启用特权审计

SQL> select user_name, privilege, success, failure from dba_priv_audit_opts ;

USER_NAME PRIVILEGE SUCCESS FAILURE
------------------------------ ---------------------------------------- ---------- ----------
SCOTT SELECT ANY TABLE BY ACCESS BY ACCESS

--步骤4：连接到scott账户操作

SQL> conn scott/tiger
已连接。
SQL> select * from win.accp;

TID
----------
1001

--步骤5：检查审计跟踪

SQL> select username, to_char(timestamp,'yyyy:mm:dd:hh'), action_name
from dba_audit_trail where username= 'SCOTT';

USERNAME TIME ACTION_NAME
------------------------------ ------------- ----------------------------
SCOTT 2008:10:29:01 SELECT

--步骤6：清空审计记录

SQL> delete from sys.aud$ ;
