The term Internet of Things is generally recognized at home and abroad as being first proposed by Professor Ashton of the MIT Auto-ID Center in 1999 when he was studying RFID. In the report of the same name released by the International Telecommunication Union (ITU) in 2005, the definition and scope of the Internet of Things have changed, and the coverage has been greatly expanded. It no longer only refers to the Internet of Things based on RFID technology.

The Internet of Things is a network based on information carriers such as the Internet and traditional telecommunications networks, allowing all ordinary physical objects that can be independently addressed to achieve interconnection and interoperability.

Software engineering is a discipline that studies the use of engineering methods to build and maintain effective, practical and high-quality software. It involves programming languages, databases, software development tools, system platforms, standards, design patterns, etc.

In modern society, software is used in many aspects. Typical software includes email, embedded systems, human-computer interfaces, office suites, operating systems, compilers, databases, games, etc. At the same time, computer software is used in almost every industry, such as industry, agriculture, banking, aviation, government departments, etc. These applications promote economic and social development, and also improve work efficiency and life efficiency.

Information security mainly includes the following five aspects, that is, the confidentiality, authenticity, integrity, unauthorized copying and security of the parasitic system need to be ensured. Information security itself covers a wide range, including how to prevent the leakage of commercial enterprise secrets, prevent teenagers from browsing inappropriate information, and prevent the leakage of personal information, etc.

The information security system in the network environment is the key to ensuring information security, including computer security operating systems, various security protocols, security mechanisms (digital signatures, message authentication, data encryption, etc.), up to the security system, Such as

UniNAC, DLP, etc., as long as there are security holes, they can threaten global security. Information security means that information systems (including hardware, software, data, people, physical environment and infrastructure) are protected from being destroyed, altered or leaked by accidental or malicious reasons. The system operates continuously, reliably and normally, information services are not interrupted, and business continuity is ultimately achieved.

Information security

The subject of information security can be divided into two levels: narrow security and broad security. Security in the narrow sense is based on the field of computer security based on cryptography. In the early days of China's information security The major is usually based on this, supplemented by computer technology, communication network technology and programming; information security in a broad sense is a comprehensive subject, from traditional computer security to information security. Not only the name change is also an extension of the development of security. Security is no longer a purely technical issue, but a product that combines management, technology, legal and other issues. This major cultivates senior information security professionals who can engage in computer, communications, e-commerce, e-government, e-finance and other fields.

"Information Engineering" in English is Information Engineering. Information Engineering is a specialized discipline based on very large scale integrated circuit technology and modern computer technology that studies information processing theory, technology and engineering implementation. This major focuses on the study of application technologies of information systems and control systems, and plays a very important role in the process of information socialization in the 21st century. Information engineering is a general term for technical methods formed by applying the principles of information science to the industrial and agricultural production sectors.
