The essential guide to understanding and using firewalls to protect personal computers and your network An easy-to-read introduction to the most commonly deployed network security device Understand the threats firewalls are designed to protect against Learn basic firewall architectures, practical deployment scenarios, and common management and troubleshooting tasks Includes configuration, deployment, and management checklists Increasing reliance on the Internet in both work and home environments has radically increased the vulnerability of computing systems to attack from a wide variety of threats. Firewall technology continues to be the most prevalent form of protection against existing and new threats to computers and networks. A full understanding of what firewalls can do, how they can be deployed to maximum effect, and the differences among firewall types can make the difference between continued network integrity and complete network or computer failure. Firewall Fundamentals introduces readers to firewall concepts and explores various commercial and open source firewall implementations--including Cisco, Linksys, and Linux--allowing network administrators and small office/home office computer users to effectively choose and configure their devices. Firewall Fundamentals is written in clear and easy-to-understand language and helps novice users understand what firewalls are and how and where they are used. It introduces various types of firewalls, first conceptually and then by explaining how different firewall implementations actually work. It also provides numerous implementation examples, demonstrating the use of firewalls in both personal and business-related scenarios, and explains how a firewall should be installed and configured. Additionally, generic firewall troubleshooting methodologies and common management tasks are clearly defined and explained.

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. He coordinated a team of Security engineers in Brazil and holds the CISSP, CCSP, and three CCIE certifications (Routing/Switching, Security, and Service Provider). A frequent speaker at Cisco Live, he holds a degree in electronic engineering from the Instituto Tecnológico de Aeronáutica (ITA – Brazil). ¿ ·¿¿¿¿¿¿¿ Create advanced security designs utilizing the entire Cisco firewall product family ·¿¿¿¿¿¿¿ Choose the right firewalls based on your performance requirements ·¿¿¿¿¿¿¿ Learn firewall¿ configuration fundamentals and master the tools that provide insight about firewall operations ·¿¿¿¿¿¿¿ Properly insert firewalls in your network’s topology using Layer 3 or Layer 2 connectivity ·¿¿¿¿¿¿¿ Use Cisco firewalls as part of a robust, secure virtualization architecture ·¿¿¿¿¿¿¿ Deploy Cisco ASA firewalls with or without NAT ·¿¿¿¿¿¿¿ Take full advantage of the classic IOS firewall feature set (CBAC) ·¿¿¿¿¿¿¿ Implement flexible security policies with the Zone Policy Firewall (ZPF) ·¿¿¿¿¿¿¿ Strengthen stateful inspection with antispoofing, TCP normalization, connection limiting, and IP fragmentation handling ·¿¿¿¿¿¿¿ Use application-layer inspection capabilities built into Cisco firewalls ·¿¿¿¿¿¿¿ Inspect IP voice protocols, including SCCP, H.323, SIP, and MGCP ·¿¿¿¿¿¿¿ Utilize identity to provide user-based stateful functionality ·¿¿¿¿¿¿¿ Understand how multicast traffic is handled through firewalls ·¿¿¿¿¿¿¿ Use firewalls to protect your IPv6 deployments ¿ This security book is part of the Cisco Press Networking Technology Series.

The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production
