Cisco Firewalls 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. ¿ Alexandre Matos da Silva Pires de Moraes, CCIE No. 6063, has worked as a Systems Engineer for Cisco Brazil since 1998 in projects that involve not only Security and VPN technologies but also Routing Protocol and Campus Design, IP Multicast Routing, and MPLS Networks Design.

Product Description Firewalls have ample recognition as key elements on the field of protecting networks. Even though this is not a new subject, many important concepts and resources, which could be helpful to designing a secure network, are often overlooked or even ignored. This book unveils the potential of Cisco firewall products and functionalities, and demonstrates how they can be grouped, in a structured manner, in order to build security solutions. The text is written in such a way that instructive linkages between theory and practice are naturally created, thus contributing to a better understanding of the most relevant concepts, and preparing the reader for the production of solid designs. The motivation for writing this book is associated with a simple axiom assumed: The better you understand how individual features operate, the better you can use them for design purposes. After all, producing better security designs is the aim of anyone truly committed to security. The book is organized in 17 chapters, as follows: Chapter 1. Firewalls and Network Security Chapter 2. Cisco Firewall Families Overview Chapter 3. Configuration Fundamentals Chapter 4. Learn the Tools. Know the Firewall Chapter 5. Firewalls in the Network Topology Chapter 6. Virtualization in the Firewall World Chapter 7. Through ASA without NAT Chapter 8. Through ASA using NAT Chapter 9. Classic IOS Firewall Overview Chapter 10. IOS Zone Policy Firewall Overview Chapter 11. Additional Protection Mechanisms Chapter 12. Application Inspection Chapter 13. Inspection of Voice Protocols Chapter 14. Identity on Cisco Firewalls Chapter 15. Firewalls and IP Multicast Chapter 16. Cisco Firewalls and IPv6 Chapter 17. Firewall Interactions Appendix A - NAT and ACL changes in ASA 8.3 Foreword (by Yusuf Bhaiji) Networks today have outgrown exponentially both in size and complexity, becoming more multifaceted and increasingly challenging to secure. The blueprint of a core network requires a strong foundation, which can be simply provided with an integrated firewall architecture cemented at the core of the system. Today, the firewall has become a core entity within a network and an integral part of every network infrastructure. Cisco Firewalls by Alexandre M. S. P. Moraes, has taken a stab at unleashing some of the fundamentally missed concepts, providing readers with a complete library of the entire family of Cisco Firewall products in a single binder. Alexandre has used a unique approach in explaining the concepts and architecture of the firewall technology. His distinct style has proven his skill at writing on a difficult subject using easy to understand illustrations that walk the reader through a step-by-step approach that shows the theory in action. He has combined some of the commonly used tools with the outputs from several commands to demonstrate the understanding of the technology and exemplifying how it works. Cisco Firewalls is unlike any other book on this subject and cannot be categorized as a configuration guide or command syntax manual. It provides the readers with the key tools and essential techniques to understand the wide-ranging Cisco firewall portfolio. Whether you are just a beginner trying to learn Cisco firewalls or an experienced engineer looking for a reference, there is something for everyone in this book at varying levels. Cisco Firewalls is an essential reference in designing, implementing, and maintaining today's highly secured networks. It is a must read and a must have in your collection - Magnum Opus! Yusuf Bhaiji; Sr. Manager, Expert Certifications (CCIE, CCDE, CCAr) 'Alexandre has worked with Cisco Security technologies since the year 2000 and is a well recognized expert in the LATAM Security community. He is a frequent speaker at Cisco Networkers and other Security conferences and has helped on training partners and customers in Brazil. In this book, he 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. From the configuration fundamentals to advanced topics such as Voice Inspection, Multicast, IPv6 and Identity-based firewalls, the book unveils important details about the operations of Cisco firewalls solutions, enabling the reader to better use this knowledge on Security Design. A must read !' Luc Billot, Security Consulting Engineer at Cisco (Emerging Markets and European Market) 'I think that Alexandre's book could have the alternative title 'Cisco Firewalls illustrated'. The way in which he links theory and practice is really insightful and greatly helps on understanding individual features and making better use of them for Security design. Definitely a reference work in the subject!' Louis Senecal, CCIE 2198, Consulting Systems Engineer, Cisco (Canada) 'In this fully illustrated tour to the world of Cisco Firewalls, Alexandre devotes a great deal of attention to Data Center related topics. Network Virtualization architecture and protection of environments that include Virtual Machines figure among the important subjects covered in the book. For those that want to benefit from Virtualization without compromising Security, this work is highly recommended.' David Gonzalez, CISSP #99462, Consulting Systems Engineer at Cisco ( LATAM)
