Introduction

Understanding and deploying network security is a key factor in determining whether your business, which relies on the Internet, will succeed. The costs that businesses have incurred over the past few years because of security vulnerabilities are staggering. Losses are estimated to be in the billions of dollars. In addition to the direct costs to your business if you suffer a network security compromise, you can also put other businesses or Internet users at risk because the compromise you suffered can be leveraged to attack against other network devices. This problem has become so serious that in some areas of government there are discussions on whether a business or individual can be held liable in this situation.

This book provides you with complete step-by-step processes using the Cisco Adaptive Security Device Manager (ASDM) in conjunction with Cisco Security Agent (CSA) host intrusion prevention software to ensure that your security posture is strong enough to stand up against any network or host attack, whether sourced from the Internet or from inside your own network.
