Features: This book combines theory and practical examples, serving as a practical guide to information security and Linux firewall source code, as well as an ideal reference for firewall researchers and technical developers. By analyzing Linux network source code, the book provides an in-depth discussion of firewall functionalities implemented in the stable version of the Linux kernel (Linux 2.4 kernel). The book primarily covers prerequisites for firewalls, fundamental firewall principles, new firewall technologies (such as connection tracking, dynamic packet filtering, source NAT, and destination NAT, etc.), firewall configuration and policies, the design of firewall functional modules, related knowledge (such as intrusion detection systems, firewall data encryption techniques, firewall architectures, etc.), data structures and system calls related to reading Linux source code and writing firewall modules, as well as the source code of firewall encryption algorithms and firewall products from influential firewall vendors in the market.
