Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.


Configure the SUSE operating system password history to prohibit the reuse of a password for a minimum of five generations.

Edit '/etc/pam.d/common-password' and edit the line containing '' to contain the option 'remember=5 use_authtok' after the third column.
