Recommended security practices and firewall configurations can help protect a process control network from attacks that originate from outside the network. Such practices include ensuring applications and servers are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that must be evaluated case by case. Sensitive application servers should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system.
