Process Control
Nuclear power plants, SCADA networks, smart grids, (public) transportation networks, etc. are vulnerable for cyber attacks. Firewalls, DMZ or stepping stone measures can be misconfigured, manipulated or circumvented, leaving the critical (process) control network open for hackers to gain access.
Products
The Fox DataDiode, a perfect, hundred-percent-secure solution, transfers data—online, in real-time and continuously—between two networks of varying security levels without compromising the security of the receiving network, with support for many applications, protocols and SCADA protocols.
Fox DataDiodes are often used within process control environments where availability and continuity are a top priority.
Case Studies
Air Traffic Control
Airports want to show their personnel, passengers and on-line visitors up-to-date flight information with regards to departures and arrivals. This real-time operational data is kept at the isolated Air Traffic Control (ATC) systems and needs to be copied out of this secure environment to the airport back-office.
Due to European and national regulations, the ATC systems must be isolated from any other network to prevent unauthorised tampering with the systems.
The Fox DataDiode is deployed to transfer messages and files from the secure ATC network to the airport back-office, thus guaranteeing 100% security against attacks aimed at the ATC systems.
(Nuclear) Power Plants
(Nuclear) power plants are part of the nations critical infrastructure. The power generating systems are monitored at all times, and reports are generated based on input and output. This requires real-time data transfers from these systems to the power plant's back-office.
It is simply not acceptable that the systems and network in the power generating environment can be tampered with by unauthorised individuals or malicious automated entities. A physical barrier between the environment and any other network – including the back-office network – is highly advisable.
The Fox DataDiode is used to allow data to leave the power generating environment and reach the back-office, while guaranteeing a 100% physical security barrier that prevents attacks the other way.
Public Transportation Systems
Most public transportation systems are currently isolated from the corporate network and the Internet. From a business perspective it is very interesting to acquire real-time information from the transportation system e.g. location of the vehicles and provide this to users who are demanding to have the most accurate information. From a security perspective the risks are too high when relying on standard security devices like firewalls.
The solution is to deploy the Fox DataDiode between the transportation network and the corporate network. Ensuring that through the physically secure one-way connection, real-time status information can flow outbound, while preventing (unwanted) information to enter the critical system. Fox DataDiodes prevents hackers to manipulate the network from the insecure network.
