Abstract

With the “Internet +” era of arrival, the major colleges and universities are in the construction of the wisdom of the campus, students and teachers living with the campus network is more and more closely related, Campus network security has become the protection of the wisdom of the campus construction. Campus network security issues become increasingly serious; a single security protection has been unable to meet the current security needs. This paper analyzes the major security threats facing the campus network, and presents the campus network security protection measures from the physical layer, network layer, system layer, application layer and management of five aspects, thus constructing the campus network's overall security defense system. The system has multiple security protection for Campus Network, thus improving the security of the campus network.

2. Campus Network Security Issues

2.1. Physical Security Risk

The primary threat facing the campus network security is the physical security. Physical security threats may come from natural, environmental and technical failures and other non-human factors, for example, if the physical location of the campus network equipment design is unreasonable, it is possible to suffer water, electricity, fire or lightning damage; Physical security threats may also come from personnel failures and malicious physical attacks, such as network equipment theft or physical damage (Du, 2015).

2.2. System Vulnerabilities and Virus Intrusions

Each server in the campus network is equipped with Windows operating system or Linux operating system. On one side, in the design and implementation of the operating system itself there are some security risks, it’s difficult to avoid security vulnerabilities, computer viruses and hackers may use the operating system security vulnerabilities on the campus network attacks; on the other side, in the campus network running educational administration, personnel management, attendance management, financial management and other important application services, these applications and teachers and students are closely related, the software is generally from third-party software vendors, because the software update is not fast enough, there will inevitably be some loopholes. In the process of using the software, if found that the vulnerability is not timely, nor is it maintained, it is easy to become the object of hacking, will inevitably be threatened by the network, invasion, virus damage and data leakage, such as the student's score has been tampered with, the attendance data is destroyed, financial wages and other data were stolen or even destroyed (Xiao, 2016).
