Protect the core of the data diode system "OWCD"!

Zero Trust is not a philosophy of "abandoning boundaries." What is the "final boundary" required in all networks in the AI era?

There has been a lot of discussion about a case where OpenAI went out of control while testing intrusion capabilities in a controlled environment, leading to breaches into other companies' systems and causing impacts, which has heightened vigilance against cyber threats. The information-stealing malware (infostealer), which is the first step in intrusion, collects information from devices and sends only the useful data for intrusion to the AI, which then instructs the next steps. This process reportedly takes about a minute, and it is clever enough to evade communication monitoring. If an intrusion is allowed, attackers can cause damage at any time, potentially leading to serious consequences such as business shutdowns. OWCD physically disconnects communication in one direction. It builds a "zero trust wall" with hardware that cannot be breached by software, eliminating the possibility of attacks. It is perfectly compatible with zero trust and is chosen as the "last bastion" of multi-layered defense. Cyber attacks aim for "operational shutdowns" targeting critical infrastructure, production facilities, IoT, and SYS-LOG lines. Once breached, these areas put business continuity at risk. Measures at the "entry" point are essential, but it is also crucial to have a system that seals off the "exit" to the outside where information-stealing malware can send out the stolen data. That’s OWCD. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

OWCD, a necessary boundary-restricted data diode for IoT, production management, and healthcare.

OWCD, a necessary boundary-restricted data diode for IoT, production management, and healthcare.

Information transmission from business device networks handling production equipment and medical devices to general office systems. For cybersecurity at this boundary, start with this.

- Let's collect operational information from the PLC and visualize it. - Using IoT for factory monitoring, let's actively improve yield, enhance quality, and conduct condition monitoring. - By connecting medical devices, electronic medical records systems, and medical administration systems, let's aim to enhance the efficiency of expanding healthcare. However, there are high barriers to this. "Our equipment is vulnerable from a security standpoint, so we must keep it completely isolated." This is the mindset across various industries. To securely protect IT critical assets that have potential risks of external intrusion, information should be able to be transmitted from operational devices while remaining completely independent from external sources. That's where the data diode "OWCD" comes in. It physically shuts out signals from the outside! Zero trust actually assumes measures for horizontal deployment and upgrading authentication levels. Ransomware damage ultimately comes down to passwords being broken; it's just a matter of time. The OWCD itself requires no setup work and can be used simply and clearly. Its strength is different from routers and firewalls. In Japan, as well as in the United States and Europe, one of the important measures for cybersecurity is the one-way communication restriction, which can be achieved with "OWCD." This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video at the related link below! Please feel free to contact us.

OWCD Remote Secure Link File Sharing

OWCD Remote Secure Link File Sharing

To securely obtain information in the supply chain, there are methods like this that can strengthen cybersecurity even with partners at different levels of response.

Are you familiar with cross-domain solutions? It is an advanced cybersecurity technology for securely transferring and sharing data between networks (domains) with different security levels. However, the costs can be exorbitant... While it may lack the glamour of IT technology, often, information transmission through files is sufficient. Instead of creating a system with many invisible parts, why not just use files? Utilizing JSON is recommended. Data diodes that restrict communication to one direction—among them, the physical data diode "OWCD" that truly cuts off the line in one direction—can be effectively used to create networks that protect the supply chain just like cross-domain solutions. In meaningfully utilizing the internet, the essential systems can: - Shut out unauthorized intrusions from the source - Shut out information leaks on the receiving side There are increasing examples of SIers utilizing this in their proposals to clients. Originality is also possible when combined with various checking functions. Please make use of this to strengthen your cybersecurity. For inquiries, please visit our website through the link below.

Network monitoring essential for log collection: Data diode "OWCD"

Network monitoring essential for log collection: Data diode "OWCD"

"A one-way device that achieves 'zero backflow' just by placing it" - A lightweight data diode that guarantees the safety of SPAN mirrors at the physical layer.

Cyber attacks are now in an era where they are noticed "after the intrusion." Monitoring and log collection are the minimum line of defense for companies. However, when it comes to whether SPAN is passive but completely safe: - Misconfigurations can create bidirectional communication. - If the monitoring side (SOC/log server/NDR) is compromised, there is a risk of backflow. - Software control alone cannot achieve zero risk. - Audits are beginning to demand "backflow countermeasures for monitoring paths." In such times, the "unidirectional communication restriction device" OWCD comes into play to physically block backflow. It can be implemented simply by placing it in the existing network to realize unidirectionality. - No configuration required. - Completely blocks backflow at the physical layer. This enhances the safety of monitoring and log collection. The "five zeros" provided by the unidirectional device: - Zero backflow. - Zero unauthorized access. - Zero misconfiguration risk. - Zero operational burden. - Minimal implementation cost. It is the only option to add physical safety without changing the existing network. The adoption by infrastructure engineers is rapidly increasing. It is essential for support services. SIers, why not effectively utilize this in your cybersecurity measures sales? There is an explanatory video at the related link below! Please feel free to contact us.

Background of Data Diode Product Development and Introduction Image

Background of Data Diode Product Development and Introduction Image

About the network boundaries with important systems! We are co-creating suitable utilization methods.

The train operation management system, which is an important system of railway infrastructure, is generally operated in a closed environment that does not communicate with external sources. However, when there is a need to connect part of the train operation management system to an external network for reasons such as improving the quality of customer services like real-time information notifications to user apps (train running positions, delays, etc.) or monitoring operational status from office areas, measures will be taken to prevent intrusion from external sources into the network of the critical system. Some railway operators utilize unidirectional communication control to create an environment where no transmissions can be made to the network where the train operation management system operates. Ryosei's data diode products leverage the low latency and lightweight nature of the UDP protocol, making them suitable for on-site applications that cannot be stopped, such as log transmission and sensor data transfer. We are currently co-creating suitable utilization methods while confirming multiple use cases with our customers. *For detailed information, please refer to the attached PDF document.

How to use Remote Secure Link in the supply chain

How to use Remote Secure Link in the supply chain

Business owners have a headache [to secure the supply chain]. With OWC's Remote Secure Link, you can strengthen your defenses even against partners with different levels of security.

DX through database integration such as ERP can lead to a situation where a virus propagates within the supply chain, causing extensive damage if one mistake is made. By effectively using the data diode OWCD, which restricts communication in one direction, it is possible to minimize damage that spreads through the network. By adding file transfers such as JSON and HTTPS in addition to CSV and binary, we can clarify the responsibility boundaries and create a network that prevents everything from coming to a halt, even when the security management levels and malware countermeasures differ. OWCD physically enforces one-way communication restrictions. It may seem very plain, but by ensuring that what needs to be stopped is indeed stopped, you can use the internet in various ways while ensuring that critical systems: - Block unauthorized intrusions from the source - Block unauthorized transmissions from the receiving side (preventing malware data exfiltration) It can be utilized for various purposes, including understanding production status, IoT, and remote monitoring data collection. There are increasing examples of SIers utilizing OWCD in their proposals to customers. Please make use of it. For inquiries, please visit our company website via the link below.

Preventing the use of syslog collection circuits by malware: A prerequisite for SOC collaboration.

Preventing the use of syslog collection circuits by malware: A prerequisite for SOC collaboration.

SOC services should absolutely not be a pathway for malware intrusion. The adoption of secure measures is increasingly becoming a trend.

EDR = "micro monitoring" of terminals, SIEM = "macro monitoring" of the entire organization, and SOC = a "human team (command center)" that monitors, analyzes, and responds 24/365 using those tools. The issue is the "people" who monitor, analyze, and respond 24/365. To achieve zero trust, it is essential to continuously collect and analyze logs and monitoring data from each device, but if the system management information cannot be sent to infrastructure engineers, it becomes hopeless to conduct detailed analysis consistently. Therefore, it is a natural progression to outsource to external specialized services. However, there is no difference in connecting to the outside, and the question is how to secure it; if an intrusion occurs from there, it can be catastrophic... This is where the data diode "OWCD" comes into play! OWCD is perfect not only for the line that sends data to external SOC specialized services but also for the route that sends logs and monitoring data from OT to SIEM. It can only allow one-way flow. The adoption by infrastructure engineers is rapidly increasing. It has become indispensable for support services. For SIers, if you want to promote cybersecurity, let's effectively utilize boundary control as well. There is a video explanation linked below! Feel free to contact us.

Utilization of OWCD as Remote Maintenance

Utilization of OWCD as Remote Maintenance

Important infrastructure OT medical equipment cannot connect to the outside. However, it is problematic to restrict communication in one direction, especially for remote maintenance. There is a solution.

Previously, Microsoft provided remote desktop software (functionality) for remote control. Based on this, we offer a solution where only specific PCs can access devices on a network protected by a data diode for remote maintenance. This is used in conjunction with OWC. Data diodes are offered by multiple manufacturers, but only OWC can propose such solutions. While this technology alone does not solve everything, we will assist in building a system that aligns with your usage environment, using this as the core. For more information about OWC, please refer to our company website. There are also video explanations available! For inquiries, please use the related link below.
