Fix Recommendation

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 "pam_pwhistory.so" to contain the option "remember=5 use_authtok" after the third column.

Check Contents

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

Check that the SUSE operating system prohibits the reuse of a password for a minimum of five generations with the following command:

> grep pam_pwhistory.so /etc/pam.d/common-password

password requisite pam_pwhistory.so remember=5 use_authtok

If the command does not return a result, or the returned line is commented out, has a second column value different from "requisite", does not contain "remember" value, the value is less than "5", or is missing the "use_authtok" keyword, this is a finding.
