Fix Recommendation

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

Add the following line in "/etc/pam.d/system-auth" and "/etc/pam.d/password-auth" (or modify the line to have the required value):

password required pam_pwhistory.so use_authtok remember=5 retry=3

Check Contents

Verify the operating system prohibits password reuse for a minimum of five generations.

Check for the value of the "remember" argument in "/etc/pam.d/system-auth" and "/etc/pam.d/password-auth" with the following command:

$ sudo grep -i remember /etc/pam.d/system-auth /etc/pam.d/password-auth

password required pam_pwhistory.so use_authtok remember=5 retry=3

If the line containing "pam_pwhistory.so" does not have the "remember" module argument set, is commented out, or the value of the "remember" module argument is set to less than "5", this is a finding.
