Based on internet technology, intranets are becoming an essential part of corporate information systems today. However, internets were not originally designed with businesses in mind. It lacks the technology required for secure business transactions and communications. A challenge therefore arises for businesses with intranet, i.e. how to establish and maintain trust in an environment, which was originally designed for open access to information. More specifically, a way has to be found to secure an intranet without impinging on its inherent benefits of flexibility, interoperability and ease of use.
Unlike traditional VPNs that offer limited or inflexible security, a dynamic VPN provide both high levels of security and, equally important, the flexibility to accommodate dynamically changing groups of users and information needs. Our dynamic VPN can provide this flexibility based on a unique agent-based architecture as well as other features.
Because information can now be made available in such a flexible and fine-grained fashion, a company’s files, documents or data that had to locked in the past can now be accessed in either whole or in part to carefully selected groups of users in precisely determined ways. As a result, a dynamic VPN is an intranet enabler. It enables an intranet to offer more services and services than it could otherwise, thereby allowing the business to make more use of its information resources
To meet the challenge of establishing and maintaining trust in an open, changing environment, the best strategy is to implement what we call a dynamic VPN. In general, any VPN is a process whereby the public networks (the Internet) is secured in order to function as if it were a private network. As such, a VPN is not defined by specialized circuits or routes. Rather, it is defined by security mechanisms and procedures that allow only appointed users access to the VPN and the information that flows through it.
