This title is primarily intended for networking professionals pursuing the CCSP certification and preparing for the CSI 642-541 exam, one of five CCSP component exams. The materials, however, appeal to an even broader range of networking professionals seeking a better understanding of the Cisco SAFE Blueprint. The exam and course, known as Cisco SAFE Implementation (CSI), cover a broad range of networking security topics in the context of the overall Cisco SAFE Blueprint that guides network managers and engineers in determining which security solutions should be deployed throughout a given network. The SAFE strategy provides the foundation for migrating to secure, affordable, converged networks. It enables companies to cost-effectively deploy a modular, scalable security framework in stages and to deliver integrated network protection via high-level security products and services. CCSP CSI Exam Certification Guide (CCSP Self-Study) combines leading edge coverage of security concepts with all the proven learning and exam preparation features of the Exam Certification Guide Series from Cisco Press including the CD-ROM testing engine with over 200 questions, pre- and post-chapter quizzes and a modular book and CD organization that breaks concepts down into smaller, easy-to-absorb blocks of information.
