The problem caused by domain conventions is that password settings do not comply with the rules of the Policy Group. In this case, you need to set the response option in the domain policy to reduce the complexity of the password. (By default, the complexity must be at least 7 characters long and contain multiple letter

When the user registers and modifies, resets the password, enforces the password to achieve certain complexity, is one of the effective measures to reduce the theft number.in the code to check the complexity of the password need to use a regular expression, such as requiring
:
Access members of the System.Text.RegularExpressions namespace. If you do not fully qualify member names in your code, add an Imports statement. For more information, see Imports statements (. NET Namespaces and types).
Security
If you want to transfer passwords across the network, you need to use a secure method to transfer the data. For more information, see ASP.net Web application security.
By adding additional complexity checks, you can impro
The regular expressions currently used are as follows:
Copy Code code as follows:
(? =.*\d) (? =.*[a-za-z]) (? =.*[^a-za-z0-9]). {8,30}
The corresponding validation rule is that the password must contain letters, numbers, special characters, at least 8 characters, and a maximum of 30 characters.
This regular expression works fine in C #, but it is problematic in JavaScript.
How do you write such regular expressions in JS?
In Linux, there are several 1 ways to set the password complexity
. One is in the/etc/login.defs file, inside several options
pass_max_days #密码最长过期天数
pass_min_ Days #密码最小过期天数
pass_min_len #密码最小长度
pass_warn_age 7 #密码过期警告天数
2. Another method is to modify the/etc/pam.d/system-auth file to

Microsoft: In the face of brute-force cracking, increasing password complexity is useless.
We all hate passwords, but unfortunately, in the present and the future we can see, the main method for online authentication such as account logon still needs to use passwords. Password Authentication is sometimes annoying. In particular, some websites require that the
Modify Linux system User password length and complexity
Before modifying the length of the Linux password is to modify the/etc/login.defs file Pass_min_len parameters, but the Earth people know that this parameter is not mandatory, users can use the same short password.
The real need to limit the
"pam_cracklib.so" fields and append "minlen=10" that Line, which indicates that the minimum password length is (10-type quantity). The "Number of types" here represents the number of different character types. PAM provides 4 types of symbols as passwords (uppercase, lowercase, digits, and punctuation).
If your password uses these 4 types of symbols at the same time, and the Minlen is set to 10, the shortes
to set the password complexity under Linux:
(1) Modify/etc/login.defs file
pass_max_days #密码最长过期天数Pass_min_days #密码最小过期天数Pass_min_len #密码最小长度Pass_warn_age 7 #密码过期警告天数
(2) Modify/etc/pam.d/system-auth file
find password requisite pam_cracklib.so such a line as the following:
