Fix Recommendation

Configure the SUSE operating system to require at least eight characters be changed between the old and new passwords during a password change with the following command:

Edit "/etc/pam.d/common-password" and edit the line containing "pam_cracklib.so" to contain the option "difok=8" after the third column.

Check Contents

Verify the SUSE operating system requires at least eight (8) characters be changed between the old and new passwords during a password change.

Check that the operating system requires at least eight (8) characters be changed between the old and new passwords during a password change by running the following command:

# grep pam_cracklib.so /etc/pam.d/common-password
password requisite pam_cracklib.so difok=8

If the command does not return anything, the returned line is commented out, or has a second column value different from "requisite", or does not contain "difok", or the value is less than "8", this is a finding.
