The spread of virus on the network can be transmitted through public anonymous FTP file, or through mail and additional files of mail.There are mainly four ways to interrupt, intercept, modify and forge
Interruption is aimed at availability, which destroys system resources and makes network unavailable.
Interception takes confidentiality as the attack target, and unauthorized users gain access to system resources by some means.
Modification aims at integrity. Unauthorized users not only access but also modify data.
Forgery aims at integrity, and unauthorized users insert the forgery data into the normal transmission data PostVer 0

With the rapid development of computer technology, information network has become an important guarantee of social development. There are a lot of sensitive information, even state secrets. So it will inevitably attract all kinds of man-made attacks from all over the world (such as information leakage, information theft, data tampering, data deletion, computer virus, etc.).

Forms: virus , worm , trojan horse , spyware , etc.

A virus is software that infects a computer by inserting itself into programs that already reside in the machine. Then, when the "host" program is executed, the virus is also executed. when executed, many viruses do little more than try to transfer themselves to other programs within the computer. Some viruses, however, perform devastating actions such as degrading portions of the operating system, erasing large blocks of mass storage, or otherwise corrupting data and other programs.

In order to make the network realize the function of resource sharing, the hardware and software of the network should run normally, and then the security of data and information exchange should be guaranteed. As can be seen from the previous two sections, the abuse of resource sharing leads to network security problems. Therefore, the technical way of network security is to implement limited sharing.
