Computer Network Security and Preventive Measures in the Age of Big Data

Compared with the past, life is much more convenient now. Among them, computers have made great contributions to the convenience of people's lives. As contemporary aspiring youth, while enjoying convenience, we should also see clearly the potential dangers behind the big data era. In our daily life, we may not know much about the potential dangers of computers. This is because we use computers in a relatively small area at this time, such as a family, company or campus, and so on. If we use computers on a large scale, there is a good chance that a series of problems will break out. Therefore, the author will sum up the forms and factors threatening computer security in this paper. After understanding the factors threatening computer security, the author puts forward his own suggestions on improving computer security precautions and makes his own contribution to the unlimited development of computer in the future.
