As the speed of wired and wireless networks such as gigabit Internet and 5G mobile communication is rapidly improving, related technologies are also rapidly developing. The Internet of Things (IoT) is one such technology that is developing along with the wireless Internet. Devices are connected to each other to exchange data and provide optimal services based on this. Self-driving cars, smart homes, and smart cities can also be implemented due to the development of IoT devices.
Yea and security emerges with enhanced device connectivity. If even one connected device is allowed to intrude from the outside, the whole system may be exposed to threats, and there is a possibility that personal information and important data are naturally leaked or altered and used in crime. Therefore, several IoT-related companies are working to ensure data confidentiality and stability.
