Preventing the Syslog collection circuit from being used by malware: Conditions for Zero Trust.
One-way communication restriction device data diode "OWCD"
The compatibility of Zero Trust and data diodes is outstanding! The number of adoption cases is increasing rapidly. Let's make visible progress in secure measures!
Zero Trust is fundamentally about "not trusting," but since the premise is "connecting," there is the challenge of "how to connect under the premise of not connecting." This is where the data diode "OWCD" comes into play! When connecting control networks (OT) in factories and power plants to external networks (IT), the demand for "sending data securely through one-way communication" is increasing, and the adoption of OWCD is on the rise. 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, but if that system management information cannot be sent to infrastructure engineers, it becomes nearly impossible to conduct detailed analysis. Once breached, the consequences can be catastrophic... OWCD is perfectly suited for sending logs and monitoring data from OT to SIEM. It allows data to flow in only one direction. The adoption by infrastructure engineers is rapidly increasing. It is indispensable for support services. SIers, if you want to promote cybersecurity, let's effectively utilize boundary control as well. There is a video explanation linked below! Feel free to reach out for inquiries.

basic information
The Data Diode is based on the principle of connecting circuits that are physically separated without any cable connection, allowing data to flow in only one direction. There are no settings required for one-way communication, so there is no possibility of reverse flow. For connectionless protocols like Syslog, which are better without a connection, you simply place this physical boundary device between the collector and the source. No configuration is needed for the Data Diode. There are no configuration tasks typically associated with routers or firewalls, making operational management simple. There is also no concern about settings or passwords being compromised. Additionally, it will never respond to any incoming requests, which is strictly prohibited in mirroring. While monitoring is essential in case something happens, the boundary control that limits incoming traffic to only what is necessary is beneficial. For companies providing infrastructure engineering, how they regulate themselves offers a significant advantage in ensuring the peace of mind of their clients. If there is no need to keep a connection open on the client side, physically disconnecting it can build trust and allow focus on SIEM activities.

Price information
If you were to do the same thing with a third-party data diode, it would incur tremendous costs, but with OWCD, that's not the case. It's far easier than various settings and VLAN construction. While there is an initial investment, it is clearer than the costs arising from unclear cybersecurity, providing a different level of reassurance for management. Additionally, for SIers providing infrastructure engineering, this investment will greatly help improve customer trust. The first step toward zero trust in OT, a "symbol of safety," and the visual and physical sense of security resonate with management as well.

Applications/Examples of results
Mirroring communication signals from a switching hub for monitoring is simply about connecting the OWCD to the circuit. No special routing settings are required. It has been adopted by many companies. Furthermore, if you can limit communication in one direction for each device, such as manufacturing equipment and medical devices, it can be used anywhere, including between OT and IT, and IT to infrastructure services. This usage not only prevents intrusion but also completely separates incoming communication from unspecified sources outside the company and outgoing communication to specific destinations, thereby preventing remote operation or unauthorized data exfiltration in case of emergencies. The OWCD itself has a sales record of over 150 units. It has numerous achievements in remote monitoring of thermal power plants. While I can't discuss specifics, its utilization in critical infrastructure such as government agencies, public institutions, transportation, and important departments within companies (critical infrastructure, research labs, etc.) is steadily increasing. Among these, its application in SIEM activities is accelerating rapidly. The use of unique cybersecurity solutions provided by SIers is also on the rise!
