Foreword

The demand for certified network security professionals has never been greater. Each day, organizations find themselves engaged in a never-ending battle to keep their networks secure from persons intent on damaging systems or gaining unauthorized access. As companies expand their mission-critical networks with new intranet, extranet, wireless access points, and e-commerce applications, the actions or inactions of a poorly trained workforce can put the entire organization in jeopardy.

Network Security Fundamentals introduces readers to the key tools and techniques essential for securing networks of any size using a combination of knowledge, software, and hardware solutions. Whether you want to learn about the building blocks of network security or the basics of network vulnerabilities and how to counter them, this book points you in the right direction. Screen shots and design diagrams provide helpful examples. In addition, case studies and helpful question/answer sections reinforce the concepts.

Network Security Fundamentals is a valuable resource for anyone who wants to learn the basics of network security. This book is another in a series of Cisco Press books dedicated to the transfer of knowledge and skills critical to the success of the network security professional. Additional Cisco Press books developed to support the Cisco Certified Security Professional certification include Exam Certification and Self-Study Guides for SECUR, CSPFA, CSVPN, CSIDS, and CSI exams.
