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

Zero Trust is not a philosophy of "discarding 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 verifying intrusion capabilities in a controlled environment and infiltrated other companies' systems, raising concerns about cyber threats. The information-stealing malware (infostealer), which is the first step in an intrusion, collects information from devices and sends only the information beneficial for the 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 isolates 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, and it is also crucial to have a mechanism that seals off the "exit" to the outside where information-stealing malware can transmit stolen information. That’s OWCD. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

OWCD, the essential boundary-restricted data diode for IoT, production management, and healthcare.

Information transmission from business equipment networks handling production devices and medical equipment to general office networks. 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, and monitor conditions using IoT for factory 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 devices are vulnerable from a security standpoint, so we must keep them completely isolated." This is the mindset across various industries and the guidance from the government. To securely protect critical assets that are visibly at risk of external intrusion, we should ensure that information can be transmitted from operational devices while keeping them completely independent from external sources. In this context, we recommend the data diode "OWCD," which physically shuts out signals from the outside! Zero Trust actually assumes measures for horizontal expansion and upgrading authentication levels. Ransomware attacks ultimately compromise passwords; 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 key measures for cybersecurity is the implementation of unidirectional communication restrictions, which can be achieved with "OWCD." This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video linked below! Feel free to contact us.

Medical institutions should ensure that unnecessary communications are cut off to protect the core from ransomware attacks.

The damage caused by ransomware infections is steadily increasing. A slight improvement in convenience can lead to unexpected risks. Let's be mindful of implementing multi-layered intrusion and information leakage countermeasures.

It is said that "with zero trust in security measures, boundary control for intrusion prevention is outdated..." However, in the end, there are vulnerabilities lurking somewhere in terms of security, and intrusions occur from there. Zero trust is meant to prevent "horizontal expansion" and "authentication acquisition," and the protection of critical devices requires the premise of "not being connected." The physical data diode OWCD provides hassle-free "disconnected" boundary control. Did you know there are actually two ways to use it? One is to protect the core by "not allowing anything to intrude." The other is to prevent takeover and actual damage by "not allowing anything to exit." For ransomware viruses to cause harm, communication with malicious actors outside is essential. By shutting that out, it prevents leakage and encryption. Not only in medical institutions, but there is a rapid increase in government agencies and companies that skillfully combine OWCD to strengthen defenses while improving convenience, as well as SIers that provide these solutions. Please make use of the physical data diode OWCD. For more information, including video explanations, please refer to our website and check the related links below, including contact information.

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 are exorbitant... While it may lack the glamour of IT technology, often, communicating information 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 in one direction—among them, the physical data diode "OWCD" that truly cuts the line in one direction—can be effectively used to create a network that protects the supply chain just like a cross-domain solution. In making meaningful use of the internet, the crucial 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 can also be achieved by combining it with various checking functions. Please make use of this to strengthen your cybersecurity.

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

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

Cyberattacks are now an era of "noticing after intrusion." Log collection for monitoring is essential for corporate defense. However, while SPAN is passive, it cannot be said to be completely safe because: - Misconfiguration 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." This is where the "one-way communication restriction device" OWCD comes into play, physically blocking backflow. It can be implemented simply by placing it in the existing network, allowing for one-way data collection. - No configuration required. - Completely blocks backflow at the physical layer. It enhances the safety of monitoring and log collection. The "five zeros" provided by one-way devices: - Zero backflow. - Zero unauthorized access. - Zero misconfiguration risk. - Zero operational burden. - Minimum implementation cost. It is the only option to add physical safety without changing the existing network. The adoption by infrastructure engineers is rapidly increasing. Support services are essential; SIers, why not effectively utilize this in your cybersecurity sales efforts? There is an explanatory video at the related link below! Feel free to contact us.

Let's prevent unauthorized access from web servers with the data diode "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 verifying intrusion capabilities in a controlled environment and infiltrated other companies' systems, raising concerns about cyber threats. The information-stealing malware (infostealer), which is the first step in an intrusion, collects information from devices and sends only the useful information for the intrusion to the AI, which then instructs the next steps. This process reportedly takes about a minute. Moreover, it cleverly bypasses communication monitoring to send out the data. If an intrusion is allowed, attackers can cause damage at any time, potentially leading to serious consequences such as business shutdowns. OWCD physically isolates communication in one direction. Since external-facing web services are accessible to anyone, it is difficult to apply zero-trust mechanisms to them, making them surprisingly hard to protect. Surprisingly, cloud services are weak against new types of attacks because the management responsibility lies with the user. Intrusions often begin from such points... Cyber attacks aim for "operational shutdown," and once breached, business continuity is at risk. OWCD firmly protects the boundary and does not allow intrusions.

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.

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 common.

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 realize zero trust, it is essential to continuously collect and analyze logs and monitoring data from each device, but if the information for system management 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 external services, and the question is how to secure it; if an intrusion occurs here, it could be catastrophic... This is where the data diode "OWCD" comes into play! In addition to its use for sending data to external SOC specialized services, OWCD is also perfect for sending 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 essential for support services. For SIers, if you want to promote cybersecurity, let's effectively utilize boundary control as well. There is a video explanation at the related link below! Feel free to contact us.

How to Utilize OWCD as Remote Maintenance

Important infrastructure OT medical equipment cannot connect to the outside... However, restricting communication in one direction causes problems for remote maintenance. There is a solution.

In the past, 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 solution is used in conjunction with OWC. Data diodes are provided 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 tailored to 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.

How to Use Data Diode OWCD to Prevent the Escalation of Ransomware Damage

Invasion cost: 66,000 yen, recovery cost: 230 million yen. Let's effectively use the data diode OWCD as a communication restriction at the boundary.

The horror of ransomware lies not only in stealing data but also in its power to halt daily life. Amidst this, the "first case of autonomous ransomware" has emerged, where the entire process is executed end-to-end by AI. It steals authentication information, thoroughly investigates targets, and identifies the locations of critical business secrets and personal information... and its ability to immediately correct failures is measured in seconds. The system is encrypted without any delay until it becomes obvious that an attack has occurred, and it quickly becomes compromised. The capability to execute end-to-end attack activities without human intervention significantly shortens the detection and containment window for defenders. However, this malware sends the information it gathers to an external AI for analysis and adjusts the attack based on the results. By cutting off the communication channel to the outside, it neutralizes its movements, allowing time for situation assessment, security measures, and virus removal, thus minimizing operational downtime. The data diode "OWCD" physically restricts communication to one direction only. There are various ways to utilize boundary restrictions. It is beneficial as one of the layers of defense and works well with zero trust. For inquiries, please refer to the related links below.
