Research on Potential Security Hazards and Defense Technology Existing in Colleges and Universities’ Campus Network

Abstract

At present, the constant development of network technology has gradually increased network users and network size. Network has gone deep into people’s daily life, study, work and other fields. In colleges and universities, the teaching trial network in traditional forms has been converted into operational network combined with scientific research and logistics service. The latter undertakes the important task of teaching, research, management and foreign exchange, lastly, not only provides convenience for education, but also plays a vital role on information construction in colleges and universities. Campus network in colleges and universities is the core carrier of transferring digitized information, so its efficient running is an urgent to be solved thing at present. However, campus network in colleges and universities always suffers from a variety of hazards such as natural disaster, loopholes in management, viruses, and so far as to its own defects in architecture. If the hazards cannot be paid close attention and solved as soon as possible, campus network will be running slowly, unsteadily and even fall into a paralytic state. Based on this, the paper lists defense technology against the existed security hazards as a standpoint, carries out the detailed research.
