This paper focuses on studying the connection and differences between“information
security”,“network security”and“cyberspace security”. Through a comparative analysis of the
relevant policy documents and academic research topics, it discovers that the three words, namely,
information security, network security and cyberspace security, are often used interchangeably
or in parallel, but there has appeared the developmental trend of“information security”moving
towards“network security”and“cyberspace security”.
This paper expounds on the fact that information security, network security and cyberspace
security have three similar aspects and three different aspects. The similar aspects are: they all belong
to the field of non-traditional security; they all focus on information security; and they can be used
interchangeably, but with different implications. The different aspects are: they are derived from
different backgrounds; they are concerned with different connotations and with different extensions.
In summary, information security, network security and cyberspace security have interrelated
aspects, as well as their own unique aspects. Information security can be loosely regarded as
related to all kinds of information security issues; network security can refer to various types of
security issues brought about by the network technology; cyberspace security is specifically related
to the problems in the cyberspace, which is one of the five spaces, parallel to the land space, sea
space, sky space, and the universal space.
