Recommended security practices and firewall configurations can help protect an industrial network from attacks that originate from outside the network. Such practices include that protection, control & automation systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet,and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Protection, control & automation systems should not be used for Internet surfing, instant messaging, or receiving e-mails.
