What Is Data Diode Technology & How Does It Work?

Today's business environment is increasingly digital, and more vulnerable than ever to cyberattack. Because of this, various network security technologies have been developed to protect organizational data and infrastructures. One of the most effective of these modern technologies is the data diode. Although it is one of the most effective network security tools available, you may not have heard of this technology and know little of what it does. Below, you'll find a description of what data diode technology is and how it works.

What Is Data Diode Technology?

A data diode is a communication device that enables the safe, one-way transfer of data between segmented networks. Intelligent data diode design maintains physical and electrical separation of source and destination networks, establishing a non-routable, completely closed one-way data transfer protocol between networks. Intelligent data diodes effectively eliminate external points of entry to the sending system, preventing intruders and contagious elements from infiltrating the network. Securing all of a network’s data outflow with data diodes makes it impossible for an insecure or hostile network to pass along malware, access your system, or accidentally make harmful changes.

Data diodes allow companies to send process data in real time to information management systems for use in financial, customer service, and management decisions — without compromising the security of your network. This protects valuable information and network infrastructure from theft, destruction, tampering, and human error, mitigating potential loss of thousands of dollars and countless hours of work.

How Does Data Diode Technology Work?

A "diode" is an electronic component that only allows current to flow in one direction. Similarly, data diode technology lets information flow safely in only one direction, from secure areas to less secure systems, without permitting reverse access. A data diode also creates a physical barrier or “air gap” between the two points. This one-way connection prevents data leakage, eliminates the threat of malware, and fully protects the process control network. Moreover, a single data diode can handle data transfers from multiple servers or devices simultaneously, without bottlenecking.
