1.199 OL09-00-001110

Information

OL 9 must not allow blank or null passwords.

GROUP ID: V-271634
RULE ID: SV-271634r1091614

If an account has an empty password, anyone could log in and run commands with the privileges of that account. Accounts with empty passwords should never be used in operational environments.

Solution

Remove any instances of the "nullok" option in the "/etc/pam.d/password-auth" and "/etc/pam.d/system-auth" files to prevent logons with empty passwords.

Note: Manual changes to the listed file may be overwritten by the "authselect" program.
