Design and Implementation of Computer Network Information Security Protection Based on Secure Big Data

In the current development of information technology, big data has become one of its important features. Moreover, with the rapid development of big data related technologies, the threat degree of computer information in China is increasing. Under the background of big data, information data grows rapidly, which makes it easier for people to obtain valuable information. However, people are faced with more and more information security problems, and it is increasingly difficult to maintain information security. In this paper, based on the security big data, the factors affecting the information security of computer network are analyzed, and the specific countermeasures are studied based on the background of big data. The purpose is to provide reference for relevant personnel and improve the stability and security of data information.
