Do not allow users to reuse recent passwords. This can be accomplished by using the 'remember' option for the 'pam_unix' PAM module. In the file '/etc/pam.d/system-auth', append 'remember=5' to the line which refers to the 'pam_unix.so' module, as shown: 'password sufficient pam_unix.so


Parameter:

[number_of_last_passwords_to_remember_5]


Technical Mechanism:

Preventing re-use of previous passwords helps ensure that a compromised password is not re-used by a user.
