Abstract 
This research takes the design of computer network security protection technology in firewall products as the core, and deeply discusses the key elements, design principles and specific applications of network security protection technology in firewall products. With the rapid development of information technology, the problem of network security has become increasingly prominent, especially in the face of increasing network attacks and data leaks, it has become a top priority to build a secure and reliable network protection system. As the first line of defense of network security, the design and implementation of firewall is very important to ensure the security of the whole network system. This study first analyzes the development trend and challenges of current network security protection technology, including the diversification and complexity of network attacks and the demand for data privacy protection. On this basis, we put forward the design principles of network security protection technology in firewall products, including high efficiency, flexibility, scalability and ease of use. These principles are designed to ensure that firewall products are able to address a variety of network threats while meeting users' needs for network performance and ease of use. We have studied in detail the application of network security protection technology in firewall products. By adopting advanced packet filtering technology, status detection technology and application layer gateway technology, firewall can realize accurate control of network traffic and effective identification of potential threats. In addition, we also discuss how to further enhance the security protection capability of the firewall by integrating security components such as intrusion detection system and security event management system.
