Network Security Architectures

Product Description

Expert guidance on designing secure networks

• Understand security best practices and how to take advantage of the networking gear you already have
• Review designs for campus, edge, and teleworker networks of varying sizes
• Learn design considerations for device hardening, Layer 2 and Layer 3 security issues, denial of service, IPsec VPNs, and network identity
• Understand security design considerations for common applications such as DNS, mail, and web
• Identify the key security roles and placement issues for network security elements such as firewalls, intrusion detection systems, VPN gateways, content filtering, as well as for traditional network infrastructure devices such as routers and switches
• Learn 10 critical steps to designing a security system for your network
• Examine secure network management designs that allow your management communications to be secure while still maintaining maximum utility
• Try your hand at security design with three included case studies
• Benefit from the experience of the principal architect of the original Cisco Systems SAFE Security Blueprint

Written by the principal architect of the original Cisco Systems SAFE Security Blueprint, Network Security Architectures is your comprehensive how-to guide to designing and implementing a secure network. Whether your background is security or networking, you can use this book to learn how to bridge the gap between a highly available, efficient network and one that strives to maximize security. The included secure network design techniques focus on making network and security technologies work together as a unified system rather than as isolated systems deployed in an ad-hoc way.

Beginning where other security books leave off, Network Security Architectures shows you how the various technologies that make up a security system can be used together to improve your network's security. The technologies and best practices you'll find within are not restricted to a single vendor but broadly apply to virtually any network system. This book discusses the whys and hows of security, from threats and counter measures to how to set up your security policy to mesh with your network architecture. After learning detailed security best practices covering everything from Layer 2 security to e-commerce design, you'll see how to apply the best practices to your network and learn to design your own security system to incorporate the requirements of your security policy. You'll review detailed designs that deal with today's threats through applying defense-in-depth techniques and work through case studies to find out how to modify the designs to address the unique considerations found in your network.

Whether you are a network or security engineer, Network Security Architectures will become your primary reference for designing and building a secure network.

This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

12 of 12 people found the following review helpful Cisco Security for Network Architecture, December 2, 2004 By  Joel E. Natt (Atlanta, GA USA) - See all my reviews    This review is from: Network Security Architectures (Hardcover) Welcome to the twenty-first century in the world of computers and networking. With more issues occurring that have negative affects on the environment that information technologists work in, the knowledge of information security is slowly becoming critical. Sean Convery presents a detailed guide into the world of designing a secure network environment. Within "Network Security Architecture", Sean delves into the whys, the hows, and most importantly the cause and effect. As you examine the table of contents alone, it becomes clear that he has spent a great deal of time researching and detailing numerous different components of a network environment that have to be examined and considered for proper network security. A close look at the book's table of contents will point out different areas that any Network Engineering individual from the Junior Administrator to the Senior Architect needs to be knowledgeable in. Sean examines policy, threats and the technologies...

The author does a great job of laying out the book in a logical manner that is sure to help Security Architects take on the daunting task of network security design with a higher level of confidence. As a systems engineer responsible for large network designs, I have found this book to provide very good information for many scenarios, a multitude of good links to provide additional resources for discussed topics as well as out of scope topics, and also a good supplement for the backround knowledge required for the CCIE Security exam, for which I am currently preparing for. I consider this one as much a must have as Doyle for IP Routing or Clarke for LAN Switching.

Hinson "Gary" (New Zealand) - See all my reviews    This review is from: Network Security Architectures (Hardcover) This comprehensive textbook is ideal for information security architects tasked with designing secure networks, both as a teaching text and as a reference. It covers: - Good practice network security design guidelines ('axioms') - Purpose and definition of network security policies - Good advice on designing the network security system (i.e. the overarching network security architecture into which individual network devices must fit) from the ground up (i.e. physical security to application security, OSI layers 1 to 7) - Specific technical advice on configuring network devices for security ('hardening') - Technical descriptions of the vulnerabilities in network services, accompanied by advice on how to secure them - Typical design considerations for network perimeter ('edge') security, internal network ('campus') security and remote access (teleworker) security - Secure network management and network security management (compared and contrasted...
