Secure transfer of SCADA information

To transmit critical information, e.g. from a SCADA system to an administrative office network means potential security risks. But there are solutions that take care of security problems and at the same time enables an exchange of information.

SCADA (Supervisory Control and Data Acquisition) is a term used for systems for monitoring and controlling processes in industry and in critical infrastructure. The processes that these systems control, and monitor are often of very sensitive nature and must therefore be handled securely in order to avoid that someone without permission affects or alters its function. If that happens, critical functions can be turned off or manipulated, which can lead to major disruptions which affects many people. For many years, companies using SCADA systems have been gradually automated. At the same time, the systems become increasingly complex and control more and more socially critical functions. This makes them more vulnerable and the challenge will be to continue digitising in a secure way. At the same time, the need to transfer the information to other networks is growing to be able to work efficiently.

The transmission of sensitive information can be done by using a solution which offers secure and filtered unidirectional communication. One such solution is Advenica’s data diode DD1000i, a data diode that ensures unidirectional file transfer with built-in support for multiple file transfer protocols.
