Five essential strategies to protect Campus Network Security

Campus Network security threats come from both on-campus and off-campus. Only by attaching importance to technologies and management can we build a secure campus network.

The security of Campus Networks in domestic colleges and universities has its historical causes: In the previous network period, on the one hand, due to awareness and funding, as well as lack of technical preferences and operational awareness, there is a general tendency to focus on technology, security, and management. It is often only necessary to put a firewall between the Intranet and the Internet. Some schools even directly connect to the Internet, this provides a space for viruses and hackers to fully utilize their skills. Virus flooding, hacker attacks, information loss, and denial of service are all critical to the entire network once these security risks occur.

As an institution of higher education, how to build a relatively reliable campus network security system becomes more and more prominent. In general, to build a campus network security system, we should start from two aspects: first, adopting advanced technologies; and second, constantly improving management methods.

Campus Network Security Risks

At present, most schools are heavily underfunded in network construction, so limited funds are invested in critical equipment, and there has been no systematic investment in network security construction, as a result, the campus network is in an open state and there are no effective security warning methods and preventive measures.

Due to the lack of unified network outlets, network management software, network monitoring, and log systems, the school's network management is independent, and the lack of effective monitoring and logs on the Internet, the identity of online users cannot be uniquely identified, there are great security risks.

At the same time, the campus network email system is extremely imperfect and there is no security management or monitoring means. Network Viruses flood, causing a sharp decline in network performance and loss of important data. Therefore, there is a lack of Network-targeted anti-virus systems that are centrally managed, upgraded, and monitored. In addition, the network security awareness of campus network users is weak, and there is no sound network security management system.

It is worth noting that a considerable number of college campus network students have a very high level of computer-related technology, or even exceed the imagination of managers. In this case, how can colleges and universities ensure the safe operation of the network and provide a wide range of network resources to meet the needs of office, teaching, and Internet access for students has become a challenge. Compared with external attacks, attacks from the Internet are more terrible and more threatening. It can be seen that the security environment of campus networks in many colleges and universities can be described as "internal and external traffic.

Campus Network Security breakthrough in management

So how can we solve this "internal and external traffic" security dilemma? In view of the current situation of campus network security in colleges and universities, it is sufficient to prevent attacks from outside the campus network under the defense system consisting of anti-virus software, firewall or smart gateway. The following five security policies are required for colleges and universities:

To standardize exit management and implement the overall security architecture of the campus network, the problem of multiple exits must be solved. Standardized and unified management of the egress enables the implementation of the campus network security system. It provides the most basic protection for campus network security.

Equipped with a complete system of network security equipment, you can configure a certain unified network security control and supervision equipment in the network and the network interface to prevent most of the attacks and damages, including: firewalls, intrusion detection systems, vulnerability scanning systems, and online anti-virus systems. In addition, security products can be configured to implement system protection, early warning, and monitoring on campus networks, effectively blocking a large amount of illegal access and unhealthy information, network faults can be quickly located and resolved.

Solves the problem of users' online identity and establishes a unified Identity Authentication System. The campus network must solve the user's online identity problem, and the identity authentication system is the foundation of the entire campus network security system. Otherwise, even if security problems are discovered, most of them can only be eliminated, only by establishing a school uniform Identity Authentication System Based on the campus network can the user's online identity problem be completely solved. At the same time, it also provides a secure and reliable guarantee for all campus information application systems.

Strictly regulate the management of Internet sites and conduct centralized monitoring and management. Internet users must not only pass the unified school-level identity authentication system, but also monitor the Internet access behavior of legitimate users. logs of Internet access behavior should be stored on the central server in a centralized manner, this ensures the legal and accurate nature of the record.

In accordance with the requirements of relevant departments, assign dedicated security management personnel and introduce a network security management system. The technology of network security is diversified, and the status quo is still "too high". Therefore, management becomes more and more important and arduous. Therefore, it is necessary to promptly fix vulnerabilities and perform regular checks, ensures network monitoring and management.
