What is a Data Diode ?

Panoptech's technology partnership with 4Secure and Owl Cyber Defence, is all about providing customers access to the latest in Cross Domain technologies used to secure digital assets.

At the core of this capability is a cost effective Data Diode Technology delivered by OWL, which this Blog aims to offer an insight into.

So what is a Data Diode ?

...... a device with two nodes or circuits—one send only and one receive only—that allows the flow of data in one direction only, from a source to a destination.

It is perhaps simplest to think of data diodes as one-way valves for data, allowing data to flow out, without a way back in.

So what is an Owl Data Diode ?

An Owl data diode goes way beyond a disabled cable; it is a hardware-based electronic device designed with two separate circuits–one send-only, and one receive-only–which physically constrain the transfer of data to one direction only and form an “air gap” between the source and destination networks. Owl provides a multi-layered, patented approach to the design of our data diodes.

Over the last 20 years, Owl has been developing and refining data diode technologies, consistently well ahead of any other competing solution. Owl solutions feature transfer rates at up to an industry-leading 10 gigabits per second, with a packet transfer latency of 2 milliseconds or less. In addition, the reliability, high bandwidth and low latency of Owl solutions means packets never require retransmission, creating a highly tuned and optimized solutions with zero data loss when operating within the specified bandwidth rate.

In order to address the expected “handshakes” or acknowledgments of two-way protocols in a one-way system, an Owl data diode employs a proxy computer on both its send and receive sides.

The source communicates with the send side proxy of the data diode. That two-way protocol is then converted to a one-way data transfer across the data diode to the receive side. Then the receive side proxy initiates a new two-way communication with the destination and completes the data transfer.
