OWCD for boundary-restricted data diodes in IoT, production management, and healthcare operations.

OWCD for boundary-restricted data diodes in IoT, production management, and healthcare operations.

Connecting business device networks that handle production equipment and medical devices with general office systems. For cybersecurity at this boundary, start with this.

- Let's collect operational information from the PLC and visualize it. - Let's actively improve yield and quality, as well as conduct condition monitoring using IoT for factory monitoring. - Let's connect medical devices, electronic medical record systems, and medical administrative systems to enhance the efficiency of expanding healthcare. However, there are high barriers: "Our devices are vulnerable from a security standpoint, so we must keep them completely isolated." This is the mindset across various industries. To securely protect IT critical assets that are potentially at risk of external intrusion, we should ensure that they are completely independent from the outside while allowing information to be shared internally. That's where "OWCD" comes in. It physically shuts out signals from the outside! Zero Trust assumes connectivity; ransomware attacks ultimately break passwords—it's just a matter of time. OWCD itself requires no configuration work and can be used simply and clearly. It frees you from maintenance tasks such as router and firewall configuration, patching, and password management. One of the definitions of cybersecurity recognized in Japan, the United States, and Europe can be realized with "OWCD," which enables one-way communication control. This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video linked below! Feel free to contact us.

Data Diode OWCD Data Secure Link

Data Diode OWCD Data Secure Link

Is data transmission safe? The data diode OWCD "Data Secure Link" can prevent intrusions by restricting communication to one direction only.

One-way communication restriction device data diode "OWCD" The recognition among infrastructure engineers and security engineers has been increasing. You are already aware of it, right? The simple structure of the data diode, which is dedicated to physically allowing communication to flow in only one direction, is well supported. However, relying solely on that capability may not be sufficient to start utilization. Therefore, we have prepared a lineup that responds to various communication needs, including converting bidirectional communication protocols to flow in only one direction, protocol conversion according to the circumstances of the receiving side, such as the internet, and even enhancing value through the collection and analysis of IoT information. Among them, one option is the data diode OWCD "Data Secure Link." It is absolutely not allowed for anything to enter internally, and it can be utilized to ensure the security of our customers. As digital transformation progresses, the operational management becomes increasingly challenging with the growing communication volume. We encourage you to utilize the data diode OWCD "Data Secure Link," which allows for easy and clear use with minimal running costs and ensures safe and secure operations. There is a video introducing the principle; please check the related link below.

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. For more information, please download the PDF or feel free to contact us.

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. Securing the supply chain can be enhanced even with different levels of partners using OWC's secure link for file 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 a data diode (OWCD) that restricts communication in one direction, it is possible to minimize damage transmitted through the network by segmenting connections to the necessary range. In addition to CSV and binary formats, incorporating file transfers such as JSON and HTTPS can clarify the responsibility boundaries and create a network that prevents everything from stopping, even when security management levels and malware countermeasures differ. OWCD physically enforces one-way communication restrictions. While it may seem very mundane, it effectively stops what needs to be stopped, allowing the internet to be used in various ways while ensuring that critical systems can: - Shut out unauthorized intrusions from the source - Shut out unauthorized transmissions from the receiving side 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 through the link below.

How to prevent file information leakage using a data diode OWCD.

How to prevent file information leakage using a data diode OWCD.

Ransomware damage is increasing, and the risks are growing. If breached, only a handful succeed in preventing data leaks. Are you implementing measures to prevent theft?

Zero Trust Security: Did you know that if you don't operate it properly at all times, you could have been breached a long time ago? With "stealth cyber attacks," half of passwords are compromised, allowing intrusions to occur openly, and 80% of unauthorized signals that you might notice later are stealthily hidden, so you remain unaware at that moment... Once it reaches this point, the probability of a bad move failing is only a few percent, allowing them to do as they please. Did you know that there are actually two ways to use OWCD? One is to protect the core without allowing intrusion. The other is to avoid actual damage by "not revealing anything." There are very few cases where simply achieving the goal by gaining access is sufficient. Once inside, the intruder can scout the system, penetrate critical areas, encrypt contents to halt operations, extract confidential information, or continuously send malicious emails... these are the actual damages. For this to happen, the virus itself must communicate with external malicious intruders and be remotely controlled. If that communication cannot occur, even if there is an intrusion, no actual damage has yet occurred, allowing time to detect and eliminate even unknown viruses. Cybersecurity: Depending on how you use OWCD, you can strengthen your defenses. Please consider it. For inquiries, please use the related link below.

Preventing the Syslog collection circuit from being used by malware: Conditions for Zero Trust.

Preventing the Syslog collection circuit from being used by malware: Conditions for Zero Trust.

The compatibility of Zero Trust and data diodes is outstanding! The number of adoption cases is steadily increasing. Let's make visible progress in secure measures!

Zero Trust is fundamentally about "not trusting," but since the premise is "connecting," there is the challenge of "how to connect under the premise of not connecting." This is where the data diode "OWCD" comes into play! When connecting operational technology (OT) networks, such as those in factories and power plants, to external networks (IT), the demand for "sending data securely via one-way communication" is increasing, leading to a rise in the adoption of OWCD. Today, we will discuss "secure transfer of Syslog" within this context. To realize Zero Trust, it is essential to continuously collect and analyze logs and monitoring data from each device, but if that system management information cannot be sent to infrastructure engineers, it becomes nearly impossible to conduct detailed analysis. Once breached, the consequences can be catastrophic... OWCD is perfect for a route that simply sends logs and monitoring data to SIEM. It only allows one-way flow. The adoption by infrastructure engineers is rapidly increasing. It is indispensable for support services. For system integrators, if you want to promote cybersecurity, let's effectively utilize boundary control as well. There is a video explanation linked below! Feel free to reach out for inquiries.

How to Use Data Diodes to Prevent Severe Ransomware Damage

How to Use Data Diodes to Prevent Severe Ransomware Damage

The intrusion of information-gathering malware cannot be completely prevented. Let's effectively use data diodes (OWCD) as a communication restriction to protect ourselves from data theft and encryption.

The horror of ransomware lies not only in its ability to steal data but also in its power to halt daily life. It steadily infiltrates deep within systems, targeting file servers and database servers to launch attacks. “Info-stealer” malware is at work, stealing authentication information and thoroughly investigating targets before launching an attack, identifying the locations of important business secrets and personal information. Unlike the moment when a system is encrypted and it becomes immediately apparent that an attack has occurred, the stealthy operation of information-gathering malware allows it to collect data without the victim realizing it, often having infiltrated days in advance and causing data leaks. This malware sends the information it has gathered back to external attackers by tracing the infiltration route. By blocking that communication channel, it secures time until other security measures or virus removals can take effect, minimizing operational downtime. Boundary control is not just for preventing intrusions. The data diode "OWCD" physically restricts communication in one direction, allowing for high security even without on-site personnel due to its physical method.
