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.

Warum braucht man eine Firewall?
Eine Firewall ist ein wichtiger Bestandteil der IT-Sicherheit, da sie das Netzwerk vor unerlaubten Zugriffen und Bedrohungen schützt. Sie überwacht den Datenverkehr zwischen dem internen Netzwerk und externen Quellen wie dem Internet und blockiert potenziell schädliche oder verdächtige Aktivitäten. Ohne eine Firewall wären sensible Daten und Systeme einem erhöhten Risiko von Cyberangriffen ausgesetzt. Sie hilft dabei, die Integrität, Vertraulichkeit und Verfügbarkeit von Informationen zu gewährleisten und ist somit unverzichtbar für die Sicherheit eines Unternehmens oder einer Organisation.
