Written by the principle architect of the original Cisco Systems SAFE Security Blueprint, Network Security Architectures is your how-to guide to designing & 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. This book shows 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. | |
