At present, although all colleges and universities have greatly improved the hardware configuration of campus network, there are still some loopholes in the setting and application of network hardware, such as the function of firewall is suppressed and the virus database is not updated in time, which gives criminals an opportunity, leading to the illegal invasion of campus network and the illegal theft of information, and may even lead to the paralysis of the whole campus network system.

At the same time, the current hacker attacks are very hidden and latent. They use their own Internet information technology to design some Trojan programs, which can successfully avoid detection and are very destructive. Once it is invaded by a Trojan horse, it will cause the loss of various functions of the computer. For example, a worm may destroy a wider area through address information in a file or network.

In addition, network viruses spread quickly and widely, and they are difficult to kill. Teachers and students are likely to be infected with network viruses when browsing or downloading files or spreading information through network interaction, which poses a threat to the information security of the whole campus network.

2. The safety awareness of users is not high.

The users of campus network are mainly students. At present, students' safety awareness in using campus network is generally not high. In addition, the current internet environment is chaotic, and all kinds of bad web pages or software with viruses are common. When students use campus network, it is easy to cause information security problems.

On the one hand, most students may think that maintaining campus network information security is the business of professional network management technicians, who just use it casually and are not responsible, which has laid many hidden dangers for network information security.

On the other hand, most students in school like surfing the Internet, often collecting or understanding various resource information, and opening web pages, connecting on demand or downloading resources at will. These behaviors are very easy to be infected with viruses and do harm to the campus network. Even if managers maintain them all the time, there will be a vicious circle.

3. Campus network management is not in place.

The importance of campus network security management is self-evident, but many colleges and universities do not have fully equipped network professional managers. The management of campus network information security is mostly reflected in the implementation and maintenance of existing computer hardware, and the special supervision of campus network security management is not in place, which leads to the low information security of campus network.

Moreover, most colleges and universities have few professionals in Internet implementation and maintenance, so they can't effectively detect the security status of campus network information. When virus attacks or hacker attacks occur, they can't take the best plan to stop them in time.

In addition, the relevant management mechanism is not perfect, there are some security management loopholes, and the maintenance of confidential documents and information is not enough, which all pose a threat to the information security of the campus network.
