关于Oracle12c 密码加固金融行业都是有要求的，这里做一个测试记录。

1、创建一个用户
SYS@orcl1> create user roidba identified by roidba;
create user roidba identified by roidba
*
ERROR at line 1:
ORA-28003: password verification for the specified password failed
ORA-20001: Password same as or similar to user  --出现报错，提示密码验证失败。

2、查看profile
SYS@orcl1> select * from dba_profiles;

ora12c_strong_verify_function Function Password Requirements
The ora12c_strong_verify_function function fulfills the Department of Defense Database Security Technical Implementation Guide requirements.

This function checks for the following requirements when users create or modify passwords:

The password must contain at least 2 upper case characters, 2 lower case characters, 2 numeric characters, and 2 special characters. These special characters are as follows:
--要求至少2个大写，两个小写，2个数字，2个特殊字符
‘ ~ ! @ # $ % ^ & * ( ) _ - + = { } [ ] \ / < > , . ; ? ' : | (space) 
The password must differ from the previous password by at least 4 characters.

The following internal checks are also applied:

The password contains no fewer than nine characters and does not exceed 30 characters.
The password does not contain the double-quotation character ("). It can be surrounded by double-quotation marks, however.

4、根据要求重新创建一个用户

SYS@orcl1> create user roidba identified by "FXlv12!@";

User created.
SYS@orcl1> grant connect to roidba;

Grant succeeded.

SYS@orcl1> conn roidba/"FXlv12!@"
Connected.
ROIDBA@orcl1>

5、取消密码复杂度验证

SYS@orcl1> ALTER PROFILE DEFAULT LIMIT PASSWORD_VERIFY_FUNCTION NULL;

Profile altered.

SYS@orcl1> alter user roidba identified by roidba;

User altered.

SYS@orcl1> 

6、设置密码复杂度验证操作过程

Enabling Password Complexity Verification
The utlpwdmg.sql script can be customized to enable password complexity verification.

Log in to SQL*Plus with administrative privileges.
For example:

CONNECT SYSTEM
Enter password: password
Run the utlpwdmg.sql script (or your modified version of this script) to create the password complexity functions in the SYS schema.
@$ORACLE_HOME/rdbms/admin/utlpwdmg.sql
Grant any users who must use this function the EXECUTE privilege on it.
For example:

GRANT pmsith EXECUTE ON ora12c_strong_verify_function;
In the default profile or the user profile, set the PASSWORD_VERIFY_FUNCTION setting to either the sample password complexity function in the utlpwdmg.sql script, or to your customized function. Use one of the following methods:
Log in to SQL*Plus with administrator privileges and use the CREATE PROFILE or ALTER PROFILE statement to enable the function. Ensure that you have the EXECUTE privilege on the function.

For example, to update the default profile to use the ora12c_strong_verify_function function:

ALTER PROFILE default LIMIT 
 PASSWORD_VERIFY_FUNCTION ora12c_strong_verify_function;
