Let's protect the core of the data diode "OWCD" system!

Let's protect the core of the data diode "OWCD" system!

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

Current cyber attacks are targeting "operational shutdown" rather than "data leakage." OWCD physically disconnects communication in one direction, fundamentally cutting off the entry or exit points. It builds a "zero trust wall" with hardware that cannot be breached by software, eliminating any opportunity for attackers. It is perfectly compatible with zero trust and is chosen as the "last bastion" of multi-layered defense. Infostealer malware reportedly sends information collected from the victim's computer to the attacker's computer in about a minute. Moreover, it cleverly bypasses communication monitoring to send out data. By the time you notice it, the attacker has already infiltrated deep within your system, allowing them to cause real damage at any time they choose. While humans are still making judgments, the attack quietly progresses, and the damage expands. If you allow reconnaissance activities by viruses, the next risk will be a direct shutdown. Therefore, it is possible to cut off communication lines. Critical infrastructure, production facilities, IoT, SYS-LOG lines—if breached, these areas put business continuity at risk. A mechanism to seal off "exits" to the outside world where information-stealing malware can send out extracted information is also essential. That is OWCD. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

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. 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 spreads throughout 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 that travels through the network by segmenting connections to the necessary range. In addition to CSV and binary formats, adding file transfers such as JSON and HTTPS can clarify the responsibility boundaries and create a network that prevents everything from coming to a halt, even when security management levels and malware countermeasures differ. OWCD physically enforces one-way communication restrictions. While it may seem very mundane, it ensures that what needs to be stopped is indeed 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 recipient 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 clients. Please make use of it. For inquiries, please visit our company website via the 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 increasing rapidly. 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 control networks (OT) in factories and power plants to external networks (IT), the demand for "sending data securely through one-way communication" is increasing, and the adoption of OWCD is on the rise. 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 perfectly suited for sending logs and monitoring data from OT to SIEM. It allows data to flow in only one direction. The adoption by infrastructure engineers is rapidly increasing. It is indispensable for support services. 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 reach out for inquiries.

Introduction to Data Diode OWCD Supporting OPC UA

Introduction to Data Diode OWCD Supporting OPC UA

The use of OPC UA is advancing in manufacturing sites, and OWCD is beneficial for strengthening intrusion prevention from office IT. Let's protect our important production equipment!

One-way communication restriction device data diode "OWCD" now supports "OPC UA communication"! OPC UA is highly flexible and platform-independent, allowing for seamless communication of various information, enabling connectivity benefits throughout the entire production process. By utilizing flags categorized by industry, unified information can be obtained even from different production equipment manufacturers, contributing to the improvement of production DX. It is expected to spread further towards the standardization of industrial communication technologies. While OPC UA can implement security measures such as encryption, connecting networks across segments can create security holes. This is where the "OWCD" comes into play. Even with firewalls and switches, maintenance can be cumbersome, and mistakes can occur, especially if outdated firmware prevents passage. The "OPC UA support" of OWCD does not require configuration for one-way communication. It is hassle-free and reliable. In the current environment where multi-layered defense against ransomware is essential, we respond to production equipment security needs such as micro-segmentation.

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.
