Check the system password length setting. Procedure: Check the password minlen option # grep pam_cracklib.so /etc/pam.d/ common-{auth,account,password,session} Confirm the minlen option is set to at least 15 as in the example below: password required pam_cracklib.so minlen=15 There may be other options on the line. If no such line is found, or the minlen is less than 15 this is a finding. |

Edit /etc/pam.d/common-password and add or edit a pam_cracklib.so entry with a minlen parameter set equal to or greater than 15. NOTE: /etc/pam.d/common-password is normally a symbolic link that points to common-password-pc or common-password-local, a file to be ‘included’ by other pam configuration files. |
