《Cisco防火墻》采用理論結合配置案例的方式，對Cisco主流的防火墻產品、功能特性和解決方案進行了全面而詳細的講解，同時還介紹了如何將這些內容應用到網絡安全設計和運維中。
《Cisco防火墻》共分為17章，主要內容包括防火墻和網絡安全概述、Cisco防火墻系列產品概述、防火墻配置基礎知識、對防火墻進行排錯所使用的工具、網絡拓撲中的防火墻、虛擬化、如何讓流量在部署或未部署NAT的環(huán)境中穿越ASA、經典IOS防火墻概述、IOS區(qū)域策略防火墻概述、其他防護機制、應用監(jiān)控、語音協(xié)議檢測、防火墻上的身份認證、防火墻與IP組播、防火墻與IPv6，以及防火墻的互動等。
對設計和實施防火墻的網絡工程師、網絡架構師來講，《Cisco防火墻》是一本必不可少的參考資料；同時，對于安全管理員、運維人員以及技術支持人士，《Cisco防火墻》也是一本難得的實用工具書；正在備考CA安全、CP安全以及CCIE安全的考生，也可以從中獲益。

Concepts, design and deployment for Cisco Stateful Firewall solutions
“ In this book, Alexandre proposes a totally different approach to the important subject of firewalls: Instead of just presenting configuration models, he uses a set of carefully crafted examples to illustrate the theory in action. A must read!” —Luc Billot, Security Consulting Engineer at Cisco
Cisco Firewalls thoroughly explains each of the leading Cisco firewall products, features, and solutions, and shows how they can add value to any network security design or operation. The author tightly links theory with practice, demonstrating how to integrate Cisco firewalls into highly secure, self-defending networks. Cisco Firewalls shows you how to deploy Cisco firewalls as an essential component of every network infrastructure. The book takes the unique approach of illustrating complex configuration concepts through step-by-step examples that demonstrate the theory in action. This is the first book with detailed coverage of firewalling Unified Communications systems, network virtualization architectures, and environments that include virtual machines. The author also presents indispensable information about integrating firewalls with other security elements such as IPS, VPNs, and load balancers; as well as a complete introduction to firewalling IPv6 networks. Cisco Firewalls will be an indispensable resource for engineers and architects designing and implementing firewalls; security administrators, operators, and support professionals; and anyone preparing for the CCNA Security, CCNP Security, or CCIE Security certification exams.
