- Mitigation SYS600cisa_csaf_ot
Hitachi Energy recommends security practices and firewall configurations to help protect process control networks from attacks that originate from outside the network. Such practices include physically protecting process control systems from direct access by unauthorized personnel, having no direct connections to the Internet, separating 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. Process control 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.
