Ensure password creation requirements are configured

低级别 2自动化cos

说明

The pam_passwdqc.so module checks the strength of passwords. It performs checks such as making sure a password is not a dictionary word, it is a certain length, contains a mix of characters (e.g. alphabet, numeric, other) and more based on the following options set in the /etc/security/passwdqc.conf: - min=disabled,disabled,disabled,disabled,14 - The password must be 14 characters or more and consists of four character classes. - max=40 - The maximum allowed password length is 40. - passphrase=3 - The number of words required for a passphrase is at least 3. - match=4 - The length of common substring required to conclude that a password is at least partially based on information found in a character string is 4. - similar=deny - The password that is similar to the old one is going to be denied. - random=47 - The size of randomly-generated passphrases in bits is 47. - enforce=everyone -...

修复方式

修复方法: 操作指南或基础设施补丁

Edit the file /etc/security/passwdqc.conf and add or modify the following lines for password length and complexity to conform to site policy: min=disabled,disabled,disabled,disabled,14 max=40 passphrase=3 match=4 similar=deny random=47 enforce=everyone retry=3 Edit the /etc/pam.d/system-auth files to include the appropriate options for pam_passwdqc.so and to conform to site policy: password required pam_passwdqc.so config=/etc/security/passwdqc.conf
