The research of computer technology promotes the application of computer

and the use of computer network processing can improve the convenience. However

when using computer technology

much secret information will be retained in the computer

causing the disclosure of personal privacy

which is not conducive to information security. Therefore

network information security has attracted increasing attention. In order to play a greater role in the computer network

it is necessary to take effective measures to deal with the hidden dangers of network information security. This paper first describes the concept and importance of computer network information security

then points out the hidden dangers of computer network information security

and finally puts forward the specific strategies of computer network information security and protection

so as to provide reference and communication for relevant people.
