IPSec: The New Security Standard for the Internet, Intranets, and Virtual Private Networks, Second Edition

Naganand Doraswamy, Dan Harkins

IPSec, the suite of protocols for securing any sort of traffic that moves over an Internet Protocol (IP) network, promises big things for online business. IPSec: The New Security Standard for the Internet, Intranets, and Virtual Private Networks catalogs the specifications that compose this suite and explain how they fit into intranets, virtual private networks (VPNs), and the Internet.Authors Doraswamy and Harkins first treat IPSec as a system, explaining how its component parts work together to provide flexible security. Their approach to this task makes sense: They first explain why standard IP packets aren't secure; then they show how the IPSec improvements make secure transactions possible. Readers get full descriptions of how various network entities talk to one another. Where appropriate, concepts that aren't specific to IPSec are explained, including IPv4 and IPv6 packet structures and addressing schemes. There's some information on cryptography too.IPSec's parts are explained individually: the Authentication Header (AH), Encapsulating Security Payload (ESP), Internet Key Exchange (IKE), and ISAKMP/Oakley protocols are detailed with lots of prose, supplemented with a smattering of packet diagrams and conceptual sketches. Sections on implementing IPSec protocols on networks remain fairly abstract and don't mention actual products, but should prove useful to programmers designing their own network security products around the IPSec specifications. - David Wall -...

In the five years since the first edition of this classic book was published, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. We've updated __Building Internet Firewalls__ to address these newer risks. What kinds of security threats does the Internet pose? Some, like password attacks and the exploiting of known security holes, have been around since the early days of networking. And others, like the distributed denial of service attacks that crippled Yahoo, E-Bay, and other major e-commerce sites in early 2000, are in current headlines. Firewalls, critical components of today's computer networks, effectively protect a system from most Internet security threats. They keep damage on one part of the network--such as eavesdropping, a worm program, or file damage--from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down. Like the bestselling and highly respected first edition, __Building Internet Firewalls,__ 2nd Edition, is a practical and detailed step-by-step guide to designing and installing firewalls and configuring Internet services to work with a firewall. Much expanded to include Linux and Windows coverage, the second edition... Leer más…

Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they're on the road. How do you provide a low-cost, secure electronic network for your organization? The solution is a virtual private network: a collection of technologies that creates secure connections or "tunnels" over regular Internet lines—connections that can be easily used by anybody logging in from anywhere. A number of products now exist to help you develop that solution. This book tells you how to plan and build a VPN. It starts with general concerns like costs, configuration, and how a VPN fits in with other networking technologies like firewalls. It continues with detailed descriptions of how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH). New features in the second edition include SSH, which is a popular VPN solution for Unix systems, and an expanded description of the IPSec standard, for which several vendors have announced support. Topics include: How the VPN compares to other available networking technologies Introduction to encryption, firewalls, the IPSec standard, and other technologies that let VPNs work Point to Point Tunneling Protocol (PPTP)...

A comprehensive overview of SSL VPN technologies and design strategies Understand how SSL VPN technology works Evaluate how SSL VPN could fit into your organisation?s security strategy Practical advice on educating users, integrating legacy systems, and eliminating security loopholes Written by experienced SSL VPN and data security professionals In Detail Virtual Private Networks (VPNs) provide remote workers with secure access to their company network via the internet by encrypting all data sent between the company network and the user?s machine (the client). Before SSL VPN this typically required the client machine to have special software installed, or at least be specially configured for the purpose. Clientless SSL VPNs avoid the need for client machines to be specially configured. Any computer with a Web browser can access SSL VPN systems. This has several benefits: Low admin costs, no remote configuration Users can safely access the company network from any machine, be that a public workstation, a palmtop or mobile phone By pass ISP restrictions on custom VPNs by using standard technologies SSL VPN is usually provided by a hardware appliance that forms part of the company network. These appliances act as gateways, providing internal services such as file shares, email servers, and applications in a web based format encrypted using SSL. Existing players and new entrants, such as Nokia, Netilla, Symantec, Whale Communications, and NetScreen... Leer más…

Expert Solutions and State-of-the-Art Code Examples SOA Using JavaTM Web Services is a hands-on guide to implementing Web services and Service Oriented Architecture (SOA) with today’s Java EE 5 and Java SE 6 platforms. Author Mark Hansen presents in explicit detail the information that enterprise developers and architects need to succeed, from best-practice design techniques to state-of-the-art code samples. Hansen covers creating, deploying, and invoking Web services that can be composed into loosely coupled SOA applications. He begins by reviewing the “big picture,” including the challenges of Java-based SOA development and the limitations of traditional approaches. Next, he systematically introduces the latest Java Web Services (JWS) APIs and walks through creating Web services that integrate into a comprehensive SOA solution. Finally, he shows how application frameworks based on JWS can streamline the entire SOA development process and introduces one such framework: SOA-J.

If you are willing to search around the internet for the same info, you will most likely find it. I just don't have the time to do it. That said, the book helped me a lot when dealing with certificates and the reason for TSL-Auth. I would have liked to have seen more diagrams and "cook book" examples. Overall it was worth the price to me, I really needed OpenVPN to work for my company and the book had just enough info to help me. Again, I would like to see more advanced examples presented, like bridging multiple networks together. Leer más…
