The SUSE operating system must not allow automatic logon via SSH.

Failure to restrict system access via SSH to authenticated users negatively impacts SUSE operating system security.

Verify the SUSE operating system disables automatic logon via SSH.

Check that automatic logon via SSH is disabled with the following command:

# sudo grep -i "permitemptypasswords" /etc/ssh/sshd_config

PermitEmptyPasswords no

If "PermitEmptyPasswords" is not set to "no", is missing completely, or is commented out, this is a finding.

Configure the SUSE operating system disables automatic logon via SSH.

Add or edit the following line in the "/etc/ssh/sshd_config" file:

PermitEmptyPasswords no
