Regulatory authorities overseeing Critical Infrastructures and Utilities have shown a growing concern regarding Cyber Terror and Cyber Crime. As a direct result, regulations, policies and requirements (from NRC, NERC, NIST and others) are becoming stricter and more rigorous.
One area addressed by all of the various regulations and policies is connections of critical (e.g.: SCADA, DCS, Production, Industrial) networks and external (business, third party, public) networks. All of the regulations urge industrial users to keep their critical assets totally segregated from external networks in order to protect against cyber terror and cyber-attacks. Users, however, need to achieve this level of segregation yet still provide staff access to industrial and operational data.
Unidirectional Security Gateway products and technologies are deployed routinely at nuclear generating sites to provide stronger-than-firewall solutions for reliability-critical equipment and control systems. Unidirectional Security Gateways provide safe IT/OT integration by replicating industrial servers and devices from generating networks to business networks through a system of hardware modules that physically prevents any attack from reaching back into the protected critical control system network. Unidirectional Gateways replace firewalls, which have proven inadequate to the needs of reliability-critical and safety-critical networks. Every path through a firewall that permits data to leave a critical network for use by an enterprise, also allows attacks to pass back into that critical network. Unidirectional Security Gateways enable safe IT/OT integration, without the serious security risks that always accompany firewalls.
