The growth of the Internet has revolutionized communication facilities. Through years, more and more communication standards and facilities emerged; e-mail and faxing direct from and to PC are examples. Now the Internet has also crept into the world of business. It was there in the business for years but was not directly involved with it. In order to accommodate new, changing and expanding groups of users and provide these users with information in a number of ways, intranets should deliver several benefits, including flexibility, interoperability, ease of use and extendibility. In particular, they should be open and and standards based, so information can be read by different users with different applications on different platforms. However, the benefits promised by intranets lead to an important challenge for businesses using this technology: how to establish and maintain trust in an environment which was designed originally for free and open access to information. The Internet was not designed with business security in mind. It was designed by universities as an open network where users could access, share and add to information as early as possible. A way has to be found to secure an intranet for businesses without impinging on the intranet€„¢s inherent benefits of flexibility interoperability and ease of use. Indeed, an ideal solution must also provide not only the highest levels of security but also security in such a way that users can easily access, modify and share more information, not less, under carefully controlled and maintained conditions. The most appropriate and successful answer to this challenge will be a DYNAMIC VIRTUAL PRIVATE NETWORK. Unlike traditional VPNs that offer limited or inflexible security, a dynamic VPN provides both extremely high levels of security and, equally important, the flexibility to accommodate dynamically changing groups of users and information needs. A dynamic VPN is actually an intranet enabler. It enables an intranet to offer more resources and services than it could otherwise, thereby allowing the business to make more use of its information resources.
