Preventing the syslog collection circuit from being used by malware: A condition of zero trust.

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

Zero Trust is fundamentally about "not trusting," but there is the challenge of "how to connect to places that cannot be fully trusted." 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), there is a growing need for "secure one-way communication to send data," leading to an increase 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. However, it is nearly impossible to constantly perform collection and analysis if we do not send the OT information, which we want to keep cleaner, to the often challenging IT side. This makes it perfect for the purpose of simply sending OT-side logs and monitoring data to the IT-side SIEM. In fact, the adoption is rapidly increasing from infrastructure engineering applications. For SIers, if you want to promote cybersecurity, let's effectively utilize boundary control to protect yourselves. There is a video explanation linked below! Feel free to reach out for inquiries.

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

The increase in ransom demands and suspension of medical services due to ransomware infections is on the rise. As IT advances, the risks also increase. Let's be mindful of implementing multi-layered intrusion prevention and information leakage measures.

It is said that with "zero trust, security measures are perfect and boundary control for intrusion prevention is outdated," but in the end, there are always security holes somewhere, leading to intrusions, and it takes days to restart the system and restore data from backups during which nothing can be done. This has been in the news, and there are even worse cases. The physical data diode OWCD provides hassle-free boundary control. Did you know that there are actually two ways to use it? One is to protect the core without allowing intrusions. The other is to "not let anything out," which prevents the actual harm of takeover. Ransomware attacks require remote communication with the outside, and by shutting that down, it prevents leaks and ransom demands for encrypted data. By combining it with access authentication and virus detection mechanisms, it enhances the overall availability of your medical system and protects your medical services. Not only in healthcare, but government agencies and companies are increasingly combining OWCD effectively to strengthen their defenses while reducing costs, as well as 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!

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.

A data diode that restricts communication in one direction, specifically the physical data diode "OWCD" that truly cuts off the line in one direction. By skillfully combining it, we can create a network that protects the supply chain. 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 Of course, it can also be combined with checking functions. How is the data being sent? Are you struggling to create a DB integration system? While it may lack the glamour of IT technology, often, information transmission via files is sufficient. Would you rather simplify things with files than create a system with many invisible parts? In the transmission and reception of documents within the supply chain, placing OWCDs on both sides can strengthen protection. If bidirectionality is necessary, it can be addressed by establishing mutual setups. 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 website through the link below.

OWCD Utilization High Security Case: Remote Desktop

Isn't the remote line for system maintenance affecting the fate of the company? A new idea to physically seal off the "invasion point" of ransomware.

Our products are equipped with overwhelming defense capabilities that "physically isolate" against both external intrusions and internal leaks. Even those who are not IT-savvy can handle it, making it a security solution that truly integrates "peace of mind in connectivity" and "protective mechanisms." Data diodes are top-class defense devices specialized in unidirectional communication, but we have received many inquiries about whether they can be used for "bidirectional communication." This is a testament to the high regard for their "protective power." VPNs used for remote maintenance are becoming increasingly ineffective due to the evolution of attack methods, making it difficult to balance intrusion prevention with rapid and efficient maintenance. Therefore, we strongly recommend a high-security configuration utilizing OWCD: Remote Desktop. Our application separates standard Windows communication and routes it through different paths, inserting OWCD to strongly block unauthorized access to the source side. This is an extremely effective method for adding "upper-layer defense" to existing environments. Furthermore, combining it with other security measures enables multilayered defense, minimizing potential damage in the event of an incident. We have received many inquiries from system integrators, and this configuration has proven results and trust. For inquiries, please visit our website at the link below ⤵.

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

Connecting IoT, production equipment, and medical devices with business device networks and general office systems. For cybersecurity measures in between, start with this.

- Let's collect operational information from the PLC and visualize it. - Using IoT for factory monitoring, let's actively improve yield, enhance quality, and conduct condition monitoring. - By connecting medical devices and electronic medical record systems with medical administrative systems, we aim to continuously enhance the efficiency of healthcare. However, there are often high barriers, and it is natural to completely isolate devices due to security vulnerabilities. To reliably protect critical IT assets that are potentially at risk of external intrusion, we should ensure that they remain 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! The setup process is unnecessary, and it can be used simply and clearly. Ransomware attacks ultimately break passwords; it's just a matter of time. There are no settings for OWCD. You are freed from maintenance tasks such as configuring routers and firewalls, applying patches, and managing passwords. One of the cyber resilience measures defined in Japan, the United States, and Europe can be realized with "OWCD," which implements one-way communication control. This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video at the related link below! Feel free to contact us.

How to use data diodes to prevent the escalation of ransomware damage

Digital transformation also emphasizes the importance of system protection. Let's effectively use data diodes (OWCD) as a communication restriction to protect ourselves from information-gathering malware reconnaissance.

The true horror of ransomware lies not in stealing data, but in its power to halt daily life. It infiltrates deep within systems, targeting file servers and database servers to launch attacks. As the name "infostealer" suggests, information-gathering malware is at work. Before launching a ransomware attack, it steals authentication credentials and thoroughly investigates the target. Unlike when files are encrypted and it's immediately obvious that an attack has occurred, information-gathering malware collects data without the victim realizing it. It steals system information, which later aids attackers when they infiltrate the system or expand their infection after gaining access. Upon investigation, it may be found that the intrusion occurred days prior, leading to data leaks. The information is sent to the attacker following the path of intrusion. By blocking the information produced by this information-gathering malware, much of the damage can be prevented. This can be achieved by equipping the system with an OWCD. The data diode "OWCD" accomplishes a physical one-way communication restriction. Moreover, since it is a physical method, it can be used safely even without on-site personnel.
