Fix Recommendation

Configure the SUSE operating system to require "pam_unix.so auth" to use SHA512.

Edit "/etc/pam.d/common-auth" and edit the line containing "pam_unix.so" to contain the option "sha512" after the third column.

Check Contents

Verify the SUSE operating system requires that "pam_unix.so auth" is configured to use SHA512

Check the algorithms used to hash system passwords with the command:

> grep pam_unix.so /etc/pam.d/common-auth
auth required pam_unix.so sha512 try_first_pass

If the command does not return anything, the returned line is commented out, or has a second column value different from "required", or does not contain "sha512", this is a finding.
