How to Use Data Diodes to Prevent Severe Ransomware Damage

The intrusion of information-gathering malware cannot be completely prevented. Let's effectively use data diodes (OWCD) as a communication restriction to protect ourselves from data theft and encryption.

The horror of ransomware lies not only in its ability to steal data but also in its power to halt daily life. It steadily infiltrates deep within systems, targeting file servers and database servers to launch attacks. “Info-stealer” malware is at work, stealing authentication information and thoroughly investigating targets before launching an attack, identifying the locations of important business secrets and personal information. Unlike the moment when a system is encrypted and it becomes immediately apparent that an attack has occurred, the stealthy operation of information-gathering malware allows it to collect data without the victim realizing it, often having infiltrated days in advance and causing data leaks. This malware sends the information it has gathered back to external attackers by tracing the infiltration route. By blocking that communication channel, it secures time until other security measures or virus removals can take effect, minimizing operational downtime. Boundary control is not just for preventing intrusions. The data diode "OWCD" physically restricts communication in one direction, allowing for high security even without on-site personnel due to its physical method.
