Abstract
Computer network is a double-edged sword, which brings convenience to people's life and work, but also brings hidden dangers, and even suffer losses, especially in recent years, the unscrupulous elements use computer network vulnerabilities to steal important data and seek improper benefits, which has caused serious network security problems. Among them, focus on the application of firewall technology can effectively prevent and supervise the existence of network security threats in the computer, control access to the Internet, and ensure the safe operation of computer networks. In this paper, from the importance of firewall, we explore the main functions, technical principles, architecture and use scenarios of cloud firewall, and propose the application in the computer network security strategy for reference.
