Recommended security practices and firewall configurations can help protect an organization network from attacks that originate from outside the network. Such practices include ensuring critical 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 that has a minimal number of ports exposed, and others that must be evaluated case by case. Critical systems 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.
