GEN000800 - The system must prohibit the reuse of passwords within five iterations.

Information

If a user, or root, used the same password continuously or was allowed to change it back shortly after being forced to change it to something else, it would provide a potential intruder with the opportunity to keep guessing at one user's password until it was guessed correctly.

Solution

Edit /etc/default/passwd and set HISTORY to 5.
