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 in the AI era?

There has been a lot of discussion about a case where OpenAI went rogue while testing intrusion capabilities in a controlled environment, leading to unauthorized access to other companies' systems and causing impacts, which has heightened vigilance against 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, 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 opportunities for 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 can jeopardize business continuity. Measures at the "entry" point are essential, but it is also crucial to have a mechanism that seals the "exit" to external sources where information-stealing malware can transmit stolen information. That’s where OWCD comes in. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

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 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.

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. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

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.

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 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.

OWCD Safe Information Dissemination for Intrusion Countermeasures

Ransomware attacks on production facilities and public infrastructure are rapidly increasing. We can achieve both intrusion prevention and the utilization of equipment data. We support visualization, analysis, and the use of AI.

Until now, information transmission from DCS/PLC has often utilized CSV or binary files (via USB memory?), but recently, the use of information aggregation to retrieve data from remote locations or leverage cloud services has increased. However, when it comes to utilizing the internet, many people hesitate due to concerns about virus intrusions such as ransomware. In fact, ransomware attacks are on the rise! Therefore, I recommend the use of the data diode OWCD, which can completely limit communication for data transmission. Since it physically restricts transmission to one direction, it frees you from various security concerns. In addition, for example: - Operational monitoring - Quality analysis - Equipment maintenance - AI analysis You can use it for these purposes. - Equipment maintenance - Improving operational efficiency - Energy management - Utilizing AI Starting from these, you can expand its use to: - Centralized monitoring - Production analysis.

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

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.
