Self-control refers to relying on one's own R&D and design, fully mastering the core technology of products, and realizing the whole process of independent R&D, production, upgrade and maintenance of information systems from hardware to software. Simply put, the core technologies, key components and all kinds of software are all produced, developed and manufactured by ourselves, and are not subject to people. Automatic control is the key link of information construction, one of the important goals to ensure information security, and it is of great significance in information security.
Controllability refers to the implementation of security monitoring and management of information and information systems to prevent information and information systems from being illegally used, which is one of the five security goals to realize information security. Self-controllable technology is to rely on its own research and development design, fully grasp the core technology of products, and realize the independent research and development, production, upgrade and maintenance of information systems from hardware to software. To put it simply, core technologies, key components and all kinds of software are all localized, independently developed and manufactured, and are not subject to people.
Internet of things:
The Internet of Things (IoT) is a network based on information carriers such as the Internet and traditional telecommunication networks, which enables all ordinary objects that can perform independent functions to be interconnected. Its application fields mainly include transportation and logistics, industrial manufacturing, medical care, intelligent environment (home, office, factory) and so on, and it has a very broad market prospect.
It was first put forward in 1999: that is, through radio frequency identification (RFID)(RFID+ Internet), infrared sensor, global positioning system,? Information sensing devices such as laser scanners and gas sensors connect any object with the Internet according to the agreed protocol, exchange information and communicate, and realize intelligent identification, positioning, tracking, monitoring and management. In short, the Internet of Things is "the Internet connected with things".
