Useful books about VPN and Security.
"Cisco ASA: All-in-One Firewall, IPS, and VPN Adaptive Security Appliance" by Omar Santos
Cisco ASA: All-in-One Firewall, IPS, and VPN Adaptive Security Appliance is a practitioner's guide to planning, deploying, and troubleshooting a comprehensive security plan with Cisco ASA. The book provides valuable insight and deployment examples and demonstrates how adaptive identification and mitigation services on Cisco ASA provide a sophisticated security solution for both large and small network environments.
The book contains many useful sample configurations, proven design scenarios, and discussions of debugs that help you understand how to get the most out of Cisco ASA in your own network.
Achieving maximum network security is a challenge for most organizations. Cisco ASA, a new unified security device that combines firewall, network antivirus, intrusion prevention, and virtual private network (VPN) capabilities, provides proactive threat defense that stops attacks before they spread through the network.
"VPNs Illustrated: Tunnels, VPNs, and IPsec" by Jon C. Snader
Virtual private networks (VPNs) based on the Internet instead of the traditional leased lines offer organizations of all sizes the promise of a low-cost, secure electronic network. However, using the Internet to carry sensitive information can present serious privacy and security problems. By explaining how VPNs actually work, networking expert Jon Snader shows software engineers and network administrators how to use tunneling, authentication, and encryption to create safe, effective VPNs for any environment.
Using an example-driven approach, VPNs Illustrated explores how tunnels and VPNs function by observing their behavior "on the wire." By learning to read and interpret various network traces, such as those produced by tcpdump, readers will be able to better understand and troubleshoot VPN and network behavior.
VPNs Illustrated gives you the knowledge of tunneling and VPN technology you need to understand existing VPN implementations and successfully create your own.
"Building Linux Virtual Private Networks" by Oleg Kolesnikov, Brian Hatch
Building Linux Virtual Private Networks (VPNs) covers the most popular VPN technologies available for the Linux platform. In the early chapters the theory behind VPNs is discussed, including needs and uses. Common network and host configurations are also covered. Subsequent chapters drill down into the implementation and configuration of specific software packages. Specific, detailed instructions are included as well as troubleshooting information. This book will be an indispensable resource for anyone who wants to implement a Linux-based VPN. This book will meet the needs of anyone, from the Linux user to the experienced administrator to the security professional.
"SSL Vpn: Understanding, Evaluating And Planning Secure, Web-based Remote Access" by Joseph Steinberg, Tim Speed, J. Steinberg, T. Speed
This book provides a detailed technical and business introduction to SSL VPN. It explains how SSL VPN devices work along with their benefits and pitfalls. As well as covering SSL VPN technologies, the book also looks at how to authenticate and educate users a vital element in ensuring that the security of remote locations is not compromised. After that, you will see strategies for making legacy applications accessible via the SSL VPN. Written in a highly readable style, it provides a vendor-neutral introduction to SSL VPN technology for system architects, analysts, and managers engaged in evaluating and planning an SSL VPN implementation.
You will learn: * How SSL VPN technology works, and how it fits into existing network architectures * Evaluating SSL VPN for your organization * What to look out for when talking to vendors * How to plan an SSL VPN implementation for your business * Educating staff to maintain SSL VPN security * Strategies for providing access to internal legacy applications via SSL VPN * Likely trends and possibilities for the future of SSL VPN
IPSec VPN Design by Vijay Bollapragada, Mohamed Khalid, Scott Wainner
IPSec VPN Design is the first book to present a detailed examination of the design aspects of IPSec protocols that enable secure VPN communication. Divided into three parts, the book provides a solid understanding of design and architectural issues of large-scale, secure VPN solutions. Part I includes a comprehensive introduction to the general architecture of IPSec, including its protocols and Cisco IOS IPSec implementation details. Part II examines IPSec VPN design principles covering hub-and-spoke, full-mesh, and fault-tolerant designs. This part of the book also covers dynamic configuration models used to simplify IPSec VPN designs. Part III addresses design issues in adding services to an IPSec VPN such as voice and multicast. This part of the book also shows you how to effectively integrate IPSec VPNs with MPLS VPNs.
IPSec VPN Design provides you with the field-tested design and configuration advice to help you deploy an effective and secure VPN solution in any environment.
Firewalls and VPNs: Principles and Practices by Richard Tibbs, Edward Oakes
This book solves the need for a resource that illustrates the principles underlying security technology, as well as provides complete hands-on exercises that will serve as valuable practice for users. Based on open-source software, this book is oriented toward the first-time networking reader. Progressive, practical exercises build confidence; SOHO (small-office-home-office) users will also be impressed with the information provided, as for these users the affordability of open-source solutions can be critical. Comprehensive coverage includes: TCP/IP and related protocols, open-source firewalls, services support and applications that firewalls protect, IPsec and TLS-based VPNs, and firewall log and log servers. An excellent reference and resource for network administrators, security administrators, chief security officers, and anyone with the following certifications: SANS, GSEC, MCSE, MCSA, CNE, A+, and Security+.
