Preventing the use of syslog collection circuits by malware: A prerequisite for SOC collaboration.

SOC services must absolutely not be a pathway for malware intrusion. The number of case studies adopting malware countermeasures is steadily increasing.

EDR = "micro monitoring" of terminals, SIEM = "macro monitoring" of the entire organization, and SOC = a "team of people (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 achieve 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. 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 remains on how to implement intrusion prevention. If an intrusion occurs from here, it could lead to catastrophic consequences... This is where the data diode "OWCD," which can restrict data transmission to one direction only, comes into play! OWCD is perfect for collecting mirroring data sent to external SOC specialized services and for sending logs from OT to SIEM. The adoption by infrastructure engineers is rapidly increasing. It has become indispensable for support services. To all SIers, if you want to promote cybersecurity, let's effectively utilize boundary control as well. There is an explanatory video linked below!

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 in an era where we realize the intrusion only after it has occurred. Log collection for monitoring is essential for corporate defense. However, while SPAN is passive, it cannot be said to be completely safe because: - Misconfigurations 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 to physically block 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 that unnecessary communications are cut off to protect the 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.

When faced with a ransomware attack, it is crucial to take measures to suppress horizontal expansion and further incursions after internal infiltration in order to mitigate damage. - Establishing checkpoints - Registering administrators Therefore, it is important to designate risk points and knowledgeable individuals, and to categorize the system so that these individuals can decide whether or not to allow data access or tasks to be performed. Some say, "With zero trust, boundary control measures against intrusions are outdated," but... Zero trust prevents "horizontal expansion" and "authentication acquisition," and the protection of critical and essential infrastructure requires the premise of "not being connected." The physical data diode OWCD provides hassle-free "not connected" boundary control. Even with the same boundary control, systems like firewalls that require authentication settings can lead to mistakes or forgetfulness. Each time personnel or systems change, and each time a virus protection patch is released, reconfiguration is necessary, and mistakes can happen at any time... AI is also targeting this, making management and costs challenging. Users who skillfully combine OWCD to strengthen defenses while improving convenience are rapidly increasing, as are the SIers providing these solutions. Please refer to our company website for more information, including video explanations. Also, check out the related links below, including contact information.

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, 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.

How to use the data diode OWCD to prevent the escalation of ransomware damage.

Communication restrictions at the boundary: Data diode OWCD. No time to waste on ransomware countermeasures. Let's use it effectively to protect the core.

The horror of ransomware lies not only in its ability to steal data but also in its power to halt daily life. Cases of "autonomous ransomware" have emerged, where attacks are executed end-to-end by AI throughout the entire process. It steals authentication information, thoroughly investigates targets, and identifies the locations of critical trade secrets and personal information... Moreover, its ability to immediately correct failures is measured in seconds. The system is encrypted, and it takes no time at all to reach a point where the damage is immediately apparent—it's all over in an instant. The capability to execute end-to-end attack activities without human intervention significantly shortens the time available for detection and containment on the defensive side. However, this malware sends the information it has captured to an external AI for analysis, which then modifies the attack based on the results. By blocking the communication channel to the outside, it can neutralize its movements, allowing time for situation assessment, security measures, and virus removal, thereby 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.
