Let's protect the data diode one-way communication restriction device "OWCD"!

Are you able to implement multi-layered defense? Can you fully protect critical infrastructure and production facilities? The only option to "physically sever" communication in one direction is "OWCD."

Cyber attacks are now aimed not at "data leaks" but at "business and operational shutdowns." As malware generation and phishing accuracy improve, attacks unfold at a speed that surpasses human thought. Firewalls, VPNs, gateways, virus checks, and access authentication software—how far can these keep up? Maintenance is challenging, and the reality is… According to a survey, it takes an average of 349 days to realize an intrusion has occurred, and by then, it has already permeated. Whether actual damage occurs depends on the intruder. While humans are still thinking about how to respond… The era of human versus human is coming to an end, and we are entering the era of machine versus machine. It is essential to have systems in place that reliably stop unnecessary communications, as well as to check important infrastructure, production equipment, IoT data collection, and SYS-LOGs. It is also crucial to block the "outlet" through which malware communicates with the outside from within the information assets that need protection. OWCD eliminates intrusions from the outside or data exfiltration by physically blocking communication in one direction. It realizes the "zero trust" barrier that cannot be fully prevented by software control through hardware. The use of multi-layered defense is rapidly increasing. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

Physical Layer One-Way Communication Restriction Device "Data Diode OWCD"

One-way shutout! A communication restriction device that physically enhances security.

The "Data Diode OWCD" is a physical one-way communication restriction device that physically limits communication to one direction. No configuration is required for one-way communication. Because there is no physical (electrical) connection, it cannot be mistakenly connected like a firewall due to configuration errors. Additionally, we provide a standard data file transfer program. When a data file is written to the transfer folder of the upstream PC, it is transferred to the output folder of the downstream PC. 【Features】 ■ No configuration required for one-way communication ■ By switching the front panel switch, it is possible to switch between one-way communication and two-way communication modes ■ Monitors the state of the switch and notifies the upstream network ■ Standard data file transfer program provided *For more details, please refer to the PDF materials or feel free to contact us.

Introduction to OWCD OPC UA Support

Let's protect important infrastructure by enhancing security measures for each line, utilizing OPC UA, which is advancing in production equipment communication.

One-way communication restriction device data diode "OWCD" introduces "OPC UA communication"! OPC UA, which is platform-independent and enables seamless communication of various information, is extremely flexible and demonstrates connectivity benefits throughout the entire production process. By utilizing flags categorized by industry, it allows for unified information even among different production equipment manufacturers, contributing to the improvement of production digital transformation (DX). It is expected to continue spreading towards the standardization of industrial communication technologies. While OPC UA can implement security measures such as encryption, being able to cross segments that do not require "dialogue" can create security holes. This is where the "OWCD" comes into play. Even with configurations using firewalls and switches in the information transmission circuit, maintenance can be cumbersome, and mistakes can occur, while outdated firmware may fail to prevent passage. The "OPC UA compatibility" of OWCD does not require any configuration for one-way communication. It is hassle-free and reliable. In the current situation where multi-layered defense against ransomware is required, we respond to production equipment security. There is a explanatory video at the related link below!
