Information security discipline can be divided into two levels: narrow security and broad security. Security in a narrow sense is the field of computer security based on cryptography, and the early information security major in China usually takes this as a benchmark, 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, it is not only a change of name, but also an extension of security development. Safety is not a purely technical issue, but a product of the combination of management, technology, law and other issues.
