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.

1. Introduction
With the vigorous development and wide application of
computer technology, the application of information network
technology represented by the Internet is becoming
increasingly popular, and the application field has gradually
expanded from small business systems to large and medium-
sized key business systems. The
computing model has also
undergone a dramatic change from the initial centralized
delivery to large processing machines,
to network-based
distributed task processing, to today's on-demand cloud
computing approach, with security increasingly becoming an
important factor affecting network effectiveness. According
to a report released by the FBI, victims of BEC fraud lost $2.4
billion in 2021, while the average cost of data breach in 2022
has exceeded $4.35 million, a record high, and cybercrime has
become the
largest type of business crime; in China,
cybersecurity is closely related to national security, and huge
economic losses are incurred every year due to hacking and
virus damage. How to strengthen network security awareness,
improve network security skills,
build a secure network
management system, and efficiently protect the safety of
information and property in the network, has become urgent.
Among many measures, the most significant is the application
of firewall technology, which not
only provides a safe and
reliable operating environment for computer networks, but
also protects against external intrusion and influence, and is
gradually recognized by people.
