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

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

Cyber attacks are now aimed at "management and operational shutdown" rather than "information leakage." The automatic generation of malware and the high precision of phishing are advancing, and attacks are unfolding at speeds that exceed human thought. Firewalls, VPNs, gateways, virus checks, and access authentication software—how far can these keep up? Maintenance is challenging, and the reality is… In a certain survey, it took an average of 349 days to realize an intrusion had occurred; in fact, infiltration had already taken place. 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 can reliably stop unnecessary communications, as well as to block the "outlets" through which malware communicates with the outside from within the information assets that need to be protected. OWCD eliminates external intrusions 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

Utilizing OPC UA, which is advancing in communication at manufacturing sites, is beneficial for strengthening security measures by line. Let's protect our important production equipment!

One-way communication restriction device data diode "OWCD" introduces "OPC UA communication"! OPC UA, which is platform-independent and seamlessly integrates various communication information, offers extremely high flexibility and demonstrates connectivity benefits throughout the entire production process. By utilizing flags categorized by each industry, unified information can be obtained even from different production equipment manufacturers, contributing to the improvement of production DX. It is expected to continue spreading towards the standardization of industrial communication technologies. While OPC UA can implement security measures such as encryption, the ability to cross segments that do not require "dialogue" can lead to security holes. This is where the "OWCD" comes into play. Even when utilizing settings with firewalls and switches in the information transmission circuit, maintenance can be cumbersome, and mistakes can occur, especially if outdated firmware prevents passage. The "OPC UA compatibility" of OWCD does not require configuration for one-way communication. It is hassle-free and reliable. In the current situation where multi-layered defense is required against ransomware, we respond to production equipment security needs. There is an explanatory video at the related link below!
