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 technologies, are rushing our SSL VPN products to meet
growing demand.
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. The book also looks at
strategies for making legacy applications accessible via the SSL VPN.
- How SSL VPN technology works, and how it fits into existing network architectures
- Evaluating SSL VPN for your organization
- Understand what to look out for when talking to vendors
- How to plan an SSL VPN implementation for your business
- Educate staff to maintain SSL VPN security
- Strategies for providing access to internal legacy applications via SSL VPN
- A heads-up on likely trends and possibilities for the future of SSL VPN
The book blends technically rigorous descriptions with a friendly
approach based on practical examples and scenarios. The authors write
in clear, informal language and make extensive use of diagrams and
images. The book begins with an overview of SSL VPN?s purpose, and the
technical and business trends that are making it popular today. It then
looks at how SSL VPNs work and how they fit into existing network
plans. The effect of SSL VPN on the wider business environment is then
considered, before looking at how SSL VPN technology is likely to
develop in the future.
This book aimed at IT network professionals and managers who are
currently evaluating SSL VPN technologies. It requires a broad
understanding of networking concepts, but does not require specific and
detailed technical knowledge of protocols or vendor implementations.
