Abstract
This article aims to delve into various aspects of firewall technology, including its definition, development history, classification, principles, main functions and roles, as well as current challenges and performance optimization suggestions. Firstly, the article provides an overview of the definition of firewall as a critical component of network security, and reviews its development history from its inception to the present. Subsequently, based on the deployment location, implementation technology, and functional characteristics of firewalls, they were classified and the working principles of various types of firewalls were elaborated in detail. Meanwhile, the article also explores the main functions and roles of firewalls in network security, such as access control and security policy implementation. In the research section of firewall technology, this article introduces packet filtering technology, state detection technology, application proxy technology, deep packet detection technology, and next-generation firewall technology, and provides a detailed analysis of the principles, characteristics, and application scenarios of these technologies. However, with the increasingly severe situation of network security, firewall technology also faces many challenges, such as diverse attack methods, difficulties in processing encrypted traffic, adaptability issues in cloud computing environments, and balancing performance and security. In response to these challenges, this article proposes performance optimization suggestions for firewalls, including introducing AI to enhance threat recognition, implementing SSL decryption and monitoring, using cloud adapted firewall solutions, and optimizing hardware and software performance. This article comprehensively analyzes various aspects of firewall technology and proposes targeted optimization suggestions, aiming to provide theoretical support and practical guidance for the further development of firewall technology.
