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.

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.

Cyber attacks are now an era of "realizing after intrusion." Log collection for monitoring is essential for corporate defense. However, when it comes to SPAN being passive yet completely safe, there are concerns: - Misconfigurations can lead to 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." In such cases, the time has come for the "one-way communication restriction device" OWCD, which physically blocks backflow. It can be implemented simply by placing it in the existing network to realize 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 the one-way device: - Zero backflow. - Zero unauthorized access. - Zero misconfiguration risk. - Zero operational burden. - Minimal 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.

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.

Medical institutions should ensure to cut off unnecessary communications to protect their core from ransomware attacks.

Damage from ransomware infections is steadily increasing. A slight improvement in convenience can lead to unexpected risks. Let's be mindful of implementing multi-layered intrusion prevention 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 security, and intrusions occur from there. Zero trust prevents "horizontal expansion" and "authentication acquisition," and it is essential to assume "not connected" for the protection of critical devices. The physical data diode OWCD provides hassle-free "not connected" boundary control. Did you know that 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." Ransomware viruses require communication with malicious actors outside. By shutting that down, it prevents leakage and encryption. By combining it with access authentication and virus detection mechanisms, we enhance the overall system's availability and protect medical care. Not limited to medical institutions, government agencies and companies that skillfully combine OWCD to strengthen security while improving convenience are rapidly increasing, as are the SIers providing these solutions. We encourage your company to utilize the physical data diode OWCD. Please refer to our website for more information, including video explanations.

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.

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

Information transmission from business device networks handling production equipment and medical devices to general office systems. 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 conduct condition monitoring using IoT for factory monitoring. - Let's connect medical devices, electronic medical record systems, and medical administrative systems to enhance the efficiency of expanding healthcare. However, there are high barriers: "Our devices are vulnerable from a security standpoint, so we must completely isolate them." 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 shared from operational devices while keeping them completely independent from external sources. That's where the data diode "OWCD" comes in. It physically shuts out signals from the outside! Zero trust actually assumes measures for horizontal expansion and upgrading authentication levels. Ransomware attacks ultimately break passwords; it's just a matter of time. The OWCD itself requires no setup work and is easy and straightforward to use. 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 one-way communication restrictions, which can be achieved with "OWCD." 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 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.
