Data Diode Network TAP

Data Diode Network TAPs are purpose-built hardware tools that allow raw data to travel only in one direction, used in guaranteeing information security or protection of critical digital systems, such as industrial control systems, from inbound cyber attacks.

Data Diodes are specifically design not to send traffic back onto the network.

A data diode, also referred to as a unidirectional network or unidirectional gateway, is a network appliance or device that allows data to travel in only one direction. Data diodes can be found most commonly in high security environments, such as federal defense and Industrial IoT, where they serve as connections between two or more networks of differing security classifications. This technology can now be found at the industrial control level for such facilities as nuclear power plants, power generation and safety critical systems like railway networks.
