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

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

Connecting business networks that handle production equipment and medical devices with general office systems: This is the first step for cybersecurity measures.

- Connect the factory monitoring IoT to the production control network to actively improve yield, enhance quality, and conduct condition monitoring. - By linking medical devices and medical record systems with medical administrative systems, we aim to continuously enhance the efficiency of healthcare. However, there are often high barriers, and the natural flow is to completely isolate "IoT-based devices due to security vulnerabilities." To securely protect critical IT assets that are potentially at risk of external intrusion, they should be kept completely independent from external access while allowing information to be shared internally. This is where "OWCD" is recommended. It physically shuts out signals from the outside, making setup unnecessary and allowing for straightforward use. One-way communication control, which is recognized as a measure for cyber resilience defined in Japan, the United States, and Europe, can be achieved. A certain company's ransomware incident targeted network devices, right? Passwords can be breached. With OWCD, you are freed from maintenance tasks such as router and firewall configuration, patching, and password management. This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video at the related link below! For inquiries, please also refer to the related link below.

Let's protect the core against external information leaks in medical institutions!

Let's protect the core against external information leaks in medical institutions!

The number of ransom demands and service suspensions due to ransomware infections is increasing. As IT advances, the risks also grow. Don't forget to implement effective intrusion and information leakage countermeasures.

It is said that with "zero trust, security measures are perfect and intrusion prevention through boundary control is outdated," but... In the end, there are security holes somewhere that allow intrusions, requiring days to restart the system and restore data from backups, during which nothing can be done. This often makes the news, and there are even worse cases. The physical data diode OWCD provides hassle-free boundary control, but did you know there are actually two ways to use it? One is to protect the core without allowing intrusions. The other is to ensure "nothing goes out," preventing the actual damage from a takeover. To take over, remote communication with the outside is essential. By shutting that down, we can counteract leaks and ransom demands for encrypted data. By combining it with access authentication and virus detection mechanisms, we enhance the overall availability of your hospital's medical system and protect patient care. Not limited to medical institutions, government agencies and companies that skillfully combine OWCD to strengthen defenses while reducing costs are rapidly increasing, as are the SIers providing these solutions. We encourage your company to consider utilizing the physical data diode OWCD. Please refer to our website for more information. There are also video explanations! Check out the related links below, including contact information.

OWCD Remote Secure Link File Sharing

OWCD Remote Secure Link File Sharing

There are also ways to obtain information within the supply chain. Even partners with a low level of responsiveness can strengthen their cybersecurity.

A data diode that restricts communication direction to one way, specifically the physical data diode "OWCD," which truly cuts off the line in one direction. By skillfully combining this in the network configuration, we can create a network that protects the supply chain. While the internet can be used in various ways, the critical systems can: - Shut out unauthorized intrusions from the source - Shut out information leaks from the receiving side Isn't it still common to attach PDF files to emails and send them to others? Perhaps sending via FTP? Even in situations where emails are simply accepted, utilizing OWCD to prevent leaks from that circuit is recommended. In the case of sending and receiving invoices in the supply chain, placing OWCD on both sides can strengthen protection. If bidirectional communication is necessary, it can be addressed by establishing mutual arrangements. The use of OWCD is increasingly being utilized by SIers in their proposals to customers. Please make use of it to strengthen your cybersecurity. For inquiries, please visit our company website through the link below.

[Information] Shirutoku Report No. 12 #Types and Features of Diodes

[Information] Shirutoku Report No. 12 #Types and Features of Diodes

Efficient power supply using SiC devices! A brief introduction to the types and features of diodes.

★★Shirutoku Report: Useful Information You Should Know★★ By changing semiconductor materials from Si to SiC (silicon carbide), the breakdown voltage of Schottky Barrier Diodes (SBD) has improved, making them usable in DC/DC converters for PCS. While performance improves with SiC, cost issues had previously hindered its adoption. However, in the last year or two, cost challenges have been addressed, leading to increased opportunities for use. This report will briefly explain the types and characteristics of diodes. 【Contents】 ■ Types and Characteristics of Diodes *For more details, please refer to the PDF document or feel free to contact us.*

[Analysis Case] Breakdown Observation of 600V Rated SiC Diode

[Analysis Case] Breakdown Observation of 600V Rated SiC Diode

Consistent analysis from preprocessing to luminescence location identification.

By using a high-voltage power supply (capable of applying up to 2000V), it is possible to induce breakdown in diodes with high breakdown voltage. In this case, a SiC Schottky diode with a breakdown voltage of 600V was operated, and by applying high voltage in the reverse direction, breakdown was induced. After removing the cathode electrode through polishing, emission microscopy observations were conducted to identify the location of the breakdown current generation. Commercially available products were used for the measurements.
