丸趣 TV 小编给大家分享一下 Oracle FGA 的示例分析，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

Oracle FGA(Fine-Grained Auditing)

一：创建 FGA;
Example 9-21 Using DBMS_FGA.ADD_POLICY to Create a Fine-Grained Audit Policy

SQL
BEGIN
DBMS_FGA.ADD_POLICY(
object_schema = HR ,
object_name = EMPLOYEES ,
policy_name = chk_hr_employees ,
enable = TRUE,
statement_types = INSERT, UPDATE, SELECT, DELETE ,
audit_trail = DBMS_FGA.DB+DBMS_FGA.EXTENDED);
END;
/

二：查看已经创建的 FGA;
At this point, if you query the DBA_AUDIT_POLICIES view, you will find the new policy listed:
SQL SELECT POLICY_NAME FROM DBA_AUDIT_POLICIES;
POLICY_NAME
——————————
CHK_HR_EMPLOYEES

三：生成审计数据
Afterwards, any of the following SQL statements log an audit event record.
SQL SELECT COUNT(*) FROM HR.EMPLOYEES WHERE COMMISSION_PCT = 20 AND SALARY 4500;
SQL SELECT SALARY FROM HR.EMPLOYEES WHERE DEPARTMENT_ID = 50;
SQL DELETE FROM HR.EMPLOYEES WHERE SALARY 1000000;
SQL select * from employees;

四：查看审计信息
SQL select lsqltext from sys.fga_log$;
LSQLTEXT
——————————————————————————–
SELECT COUNT(*) FROM HR.EMPLOYEES WHERE COMMISSION_PCT = 20 AND SALARY 4500
SELECT SALARY FROM HR.EMPLOYEES WHERE DEPARTMENT_ID = 50
DELETE FROM HR.EMPLOYEES WHERE SALARY 1000000
select * from employees

SQL select SQL_TEXT from dba_fga_audit_trail;
SQL_TEXT
——————————————————————————–
SELECT COUNT(*) FROM HR.EMPLOYEES WHERE COMMISSION_PCT = 20 AND SALARY 4500
SELECT SALARY FROM HR.EMPLOYEES WHERE DEPARTMENT_ID = 50
DELETE FROM HR.EMPLOYEES WHERE SALARY 1000000
select * from employees

五：删除 chk_hr_employees 审计
SQL exec DBMS_FGA.DROP_POLICY(object_schema= HR ,object_name= EMPLOYEES ,policy_name= chk_hr_employees
—SQL exec DBMS_FGA.DISABLE_POLICY_POLICY(object_schema= HR ,object_name= EMPLOYEES ,policy_name= chk_hr_employees
—SQL exec DBMS_FGA.ENABLE_POLICY(object_schema= HR ,object_name= EMPLOYEES ,policy_name= chk_hr_employees
