Network Security Protection Technology under the Background of Computing Big Data

Abstract

Abstract Based on the risk analysis of the network security of the radio and television critical information infrastructure, this paper introduces the evolution process of the network security protection architecture, and proposes the network security intelligent protection architecture. The article starts from the protection content and methods of physical security, network security, border security, server security, terminal security, application security, data security and backup and recovery, security management center and other technical aspects. Construction is explored. The thesis builds a reliable and stable broadcast technology center network information security system through the establishment of a network information security technology guarantee and a network information security management system.
