Internet is an open and borderless information Network world, because of its openness, it is often attacked by computer viruses and hackers, resulting in data loss and system paralysis in computers and computer networks. Therefore, the school computer network system security problem must be placed in the first place, only to ensure the network security, can ensure that our information is confidential, complete, usable, controllable, make full use of the beneficial side of the network, to provide help and service for school education and teaching.

In recent years, there have been many network security and information disclosure incidents, such as the 2017 school onion extortion software infection, disk files will be encrypted by the virus. The blackmail software uses a high intensity encryption algorithm, it is difficult to crack, the attackers only pay high ransom to decrypt the recovery file, the learning data and personal data will cause serious loss. According to the network security Agency, this is the use of the NSA hacker Arsenal leaked "Eternal Blue" launched by the virus attack incident. From the situation of the infected machine, one is the operating system, Office software, such as not the use of genuine software, and loopholes, patches update not timely; the second is not commonly used port is not closed; third, personal network security awareness indifference, there is no regular backup of documentation habits. The solution to this vulnerability is only computer-installed patches. In 2016, there was also a number of information leaks, such as Yahoo Two account information leaked, involving about 1.5 billion people account; Our country's immunization planning system was invaded and 200,000 children's information was stolen and sold; Information disclosure indirectly claimed the Xu Yuyu life of the university; According to the relevant information, Public security organs seized a total of more than 20 billion personal information disclosure in 2016, according to the type of security incident, the number of each event to be counted as follows figure.

With the rapid development of the Internet, the scale of network is expanding, the level of network application is increasing, the network security situation is not optimistic, all kinds of fishing sites, fishing two-dimensional code endless. People enjoy the convenience of the Internet and also suffer from the risk of cyber attacks and information leaks. Because the internet is widely used in the operating system is windows, there are many security vulnerabilities, vulnerable to hackers, resulting in school internal information and student information leakage. If the operating system does not timely patch upgrades and effective anti-virus, there will be significant network security risks, while the Internet needs to deploy a comprehensive network security technology measures.

Common network security technologies include identity authentication, protection wall technology, intrusion detection technology, encryption technology. Identity authentication technology is an effective solution to the process of confirming the identity of the operator in the Internet network. All the information in the network including the user's identity information is a specific set of data to indicate that the computer can only recognize the user's digital identity, all the user's authorization is also for the user's digital identity authorization. The firewall can be deployed in the school's network outside the boundary, can also be placed within the school network, to protect the network segments of the data security, the deployment of firewalls can distinguish between trusted traffic and untrusted traffic. Intrusion detection technology, as a proactive means of security protection, provides real-time protection against internal attacks, external attacks and misoperation, intercepts and responds to intrusions before the network system is compromised, and strengthens the security of the system itself. Encryption technology is the important data ―― such as passwords, into garbled transmission and calibration, to reach the end, and then restore the technology.

Encryption techniques include algorithms and two elements of the secret key. To the network system deployment omni-directional security protection, may play the network system to have the more reliable protection function. After analyzing the common network security technology, this paper formulates the network security protection strategy of campus network. The campus network is divided into service domain and user domain. A core router is interconnected between a service domain and a user domain. The service domain places a variety of servers in the campus, including authentication server, Web server, database server, etc. In order to ensure system stability and reliable redundancy, each type of server is configured as a two-machine and load balancing, firewall deployment between the core router and server, network intrusion detection equipment, firewall configured inflow and outflow rules, allowing only trusted IP addresses and ports through the network. Network intrusion detection equipment, can detect all kinds of network attacks in time. The user domain places the student computer terminal and the teacher computer terminal, may realize the campus information inquiry, the online assignment arrangement, the online job submission, the result inquiry and so on function, the user domain deploys the firewall, realizes to through the user domain each IP and the port accurate control.

The internet has deeply studied all aspects of students ' study and life, while enjoying the scientific and technological achievements in the information age, we must study the network security knowledge, raise the precaution consciousness, do well the network security protection measure, safeguard the network information security. The network security measures that adolescent students can take are shown in the figure.

To enhance the network security awareness, to establish a time to prevent network security risk awareness, because the network security hidden dangers everywhere. Carefully sweep the two-dimensional code, especially when the need for capital flow must be vigilant. Do not easily add strangers to friends, a variety of mailboxes, chat tools, Web sites, etc. should use a separate user name and password. For personal use of computers, mobile phones, pads and other Internet access terminals, to install anti-virus software, often carry out security scans, timely detection of hidden dangers. Can use identity authentication, firewall technology, intrusion detection, encryption technology, etc. do a good job of security protection. For personal name, telephone, ID number, home address, family members, schools, classes and other personal information in good custody, not to strangers leaked, to prevent criminals malicious misappropriation of personal information. For their own registered mailboxes, Web sites, the password setting of the chat tool should be more than 8 digits, and the combination of letters, numbers and special characters must not be used as the password, such as birthdays, phone numbers, etc. do not accept QQ, micro-letter in the Stranger Add Friends Invite, browse the Web site as far as possible to the official website, to prevent

The network security situation will change with the development of the Internet technology, the network security problem will not be invariable, and the security measures should be updated constantly. As educators or school administrators, it is necessary to strengthen the learning of network security knowledge and improve the Internet network security countermeasures.
