Is there a possibility that the backup storage data is actually infected with a virus and starts leaking information?

Recently, there have been a series of unauthorized intrusions and data leaks due to ransomware. With the development of generative AI, opportunities to use the internet in the office have increased, and while I believe we are protected by zero trust measures... ultimately, there are security holes somewhere that allow intrusions, requiring several days to restore the system, during which business operations come to a halt, which often makes the news. In most cases, a virus achieves its goal simply by infiltrating the target. Once inside, it scouts the target's system, burrowing into critical areas to encrypt or exfiltrate data, causing real damage. To do this, the virus itself must communicate with an external malicious intruder for remote control. If that communication cannot occur, even if an intrusion happens, the worst-case scenario has not yet unfolded, allowing time to detect and eliminate even unknown viruses. It is possible to scan incoming data. Redundancy of backup data is feasible. However, constantly scanning backed-up data for viruses is quite challenging. Depending on how it is used, defenses can be strengthened, so please consider this. For inquiries, please visit our company website linked below ⤵, where you can also find video explanations!

basic information

The OWCD will be positioned to restrict communication only in the direction from which data arrives on the data arrival route. Viruses will send information about the route they have taken to the remote operator. If this is blocked by the OWCD, they will not be able to reach the core information. Naturally, the leakage of core information will also be impossible. At first glance, it may seem that the data arrival point is completely exposed and unprotected. In reality, the OWCD does not allow TCP/IP communication to pass through. This can be utilized to filter data during protocol conversion, making it easy to use various virus check functions that you all employ. While it may not be systemically slim or aesthetically pleasing, by establishing such a barrier, we can properly check data at the responsibility boundary and protect you from viruses. The OWCD is a mechanism that limits communication to one direction on electronic circuits and prevents backflow. It is being increasingly adopted by important infrastructures such as government agencies, power plants, and transportation systems, where no margin for error is allowed, as well as by various research laboratories.

Price information

There are variations depending on the communication bandwidth. We also accept system engineering for implementation (scope, cost, and delivery time are negotiable). Please contact us through our company website as mentioned above.

Applications/Examples of results

Government agency information systems (communication backflow control for external email reception checks) Traffic information systems (one-way communication control from the control system to the public web server) Remote monitoring systems for industrial equipment (intrusion prevention at the data transmission unit) Supply chain information collection systems in the industrial sector (prevention of unauthorized access to production facilities and unauthorized data extraction at the collection side) Core information management systems in research institutes (prevention of unauthorized access to research facilities and unauthorized data extraction from data servers) As mentioned above, these systems are utilized in government agencies, power plants, defense systems, manufacturers' research institutes, and production information transmission points. For inquiries, please contact us through our company website.
