This Book is a chapter from a book on Linux firewalls. It discusses the fundamentals of packet filtering, security measures, and the implementation of firewalls using both the traditional iptables program and the newer nftables program. The chapter also provides detailed explanations of how to build and install a standalone firewall, optimize firewall rules for performance, configure firewalls for packet forwarding, and implement virtual private networks. It further delves into intrusion detection and response techniques, including log analysis, rootkit detection, and filesystem integrity checking. The chapter aims to equip readers with the knowledge and practical skills to design, implement, and maintain secure Linux firewalls.
