To ensure password changes are effective in their goals, the system must ensure old and new passwords have significant differences. Without significant changes, new passwords may be easily guessed based on the value of a previously compromised password.
Check /etc/default/passwd to verify the MINDIFF setting. # grep ^MINDIFF /etc/default/passwd If the setting is not present, or is less than eight, this is a finding.
The root role is required. # pfedit /etc/default/passwd Search for MINDIFF. Change the line to read: MINDIFF=8
