According to Prof. Le Ngoc Tho – Canada McGill University  - In the recent years, the smart environment has been gradually established with sensor networks, broadband networks and Internet of things (IoT), combined with artificial intelligence and large data analysis, has brought many advanced applications in various fields, such as health, agriculture, industrial production, smart cities and etc.

Smart environments carry a number of basic features, such as utility fullness, dependability, or interaction in simple ways; It provides smart services to better serve the lives of people. Therefore, the cost of deploying smart environments includes technologies and equipment, though they are very expensive, will be attractive to investors when managers propose a rational development direction.

However, the core issue is that today's "smart" devices are not smart, because they have sensors, but they do not have a self-recognizing and protecting mechanism. When using equipment imported from foreign countries if  we are not careful, it is easy to make many security errors can not control the system.
