Analysis of computer network security and precautions in the era of big data
Abstract：With the rapid development of big data technology, data has become a valuable resource in the new era. However, the wide application of big data also brings unprecedented computer network security challenges. In the storage, transmission and processing of massive data, security problems such as data leakage, privacy invasion and malicious attacks occur frequently, posing a serious threat to personal privacy, corporate secrets and even national security. Therefore, based on the background of the era of big data, this paper studies the problem of computer network security deeply. By analyzing the characteristics of the era of big data and the challenges of computer network security, this paper puts forward preventive measures including data encryption, multi-level defense system construction, regular security audit and software update, as well as network content supervision and regulation construction. These measures are designed to improve the security of computer networks, protect personal privacy and corporate secrets, and provide a solid security guarantee for the healthy development of big data.
