| With this concise, problem-solving guide, networking professionals will learn how to identify network security threat implement uniform security throughout their networks, secure remote dial-in access with CiscoSecure ACS and Cisco IOS AAA features, protect Internet access on their perimeter routers with the CiscoSecure IOS firewall software, and implement secure VPNs using IPSec and Cisco Encryption Technology. Step-by-step instructions and immediate solutions will help administrators implement and update security defenses. Every configuration in this book has been completely tested and perfected with actual Cisco routers.
Thanks for buying Cisco Network Security Little Black Book, the definitive guide for security configurations on Cisco routers.
New business practices and opportunities are driving a multitude of changes in all areas of enterprise networks, and as such, enterprise security is becoming more and more prevalent as enterprises try to understand and manage the risks associated with the rapid development of business applications deployed over the enterprise network. This coupled with the exponential growth of the Internet has presented a daunting security problem to most enterprises: How does the enterprise implement and update security defenses and practices in an attempt to reduce its vulnerability to exposure from security breaches?
In this book, I will attempt to bridge the gap between the theory and practice of network security and place much of its emphasis on securing the enterprise infrastructure, but first let me emphasize that there is no such thing as absolute security. The statement that a network is secure, is more often than not, misunderstood to mean that there is no possibility of a security breach. However, as you will see throughout this book, having a secure network means that the proper security mechanisms have been put in place in an attempt to reduce most of the risks enterprise assets are exposed to. I have tried to include enough detail on the theories and protocols for reasonable comprehension so that the networking professional can make informed choices regarding security technologies. Although the focus of this book is on the Cisco product offering, the principles apply to many other environments as well. |
