The only authorized Self-Study guide based on the new CCSP CSVPN 642-511 exam from Cisco Systems. 
CCSP Self-Study: Cisco Secure Virtual Private Networks (CSVPN), Second Edition, helps students sort out VPN options and applications by clearly presenting the information covered in the CSVPN course coupled with real-world examples. It will initially serve students as a valuable study aid and continue to be an invaluable lab-based theory and configuration guide for years to come. This book covers the topic of establishing Virtual Private Networks (VPNs) using Internet Protocol Security (IPSec) protocols in conjunction with long-established encryption, authentication, and hashing protocols. It concentrates on the configuration of the VPN 3000 series of products, including concentrators, hardware clients, and software clients. 
NEW TO THIS EDITION: How does this differ from the previous edition? This new book closely follows the topics that are required for the new CSVPN 642-511 exam, whereas the previous edition (1587050331) is related to the 2.0 CSVPN exam (9EO-570). New in the second edition is full, detailed coverage of the VPN 3000 Concentrator, a scalable remote access platform that offers encryption, high availability, and performance far superior to similar products.
