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.

Allowing the business to make more use of its information resources.
SECURITY MECHANISMS
Encryption Mechanisms and Standard
Authentication, Digital Signatures and Certificates
Threats and Control Points
Access Control Lists
Encryption Mechanisms and Standard
Private key
Kerberos
The Data Encryption Standard (DES)
Public key
RSA Algorithm
Authentication, Digital Signatures and Certificates
Digital Signatures
Certificates
Traditional vpn
VANs (Value Added Networks)
Routers, Firewalls and Encrypted Routers
VANs
VANs offer the advantage of fast, high-volume transfer of data
Provide this exchange of data over a secure network.
They also require dial -up connections or dedicated telephone lines, which can be expensive
Routers & firewalls
Routers
A router is a device that forwards data packets across computer networks
Router is a microprocessor-controlled device that connected to two or more data lines from different networks.
Firewalls
A firewall is a method of protecting one network from another network
Specific features
Distributes access control mechanism.
Application independence.
Access control based on strongly authenticated user identities.
Support for user groups.
capabilities
Provides “industrial-strength ” security
Accommodates dynamically changes communities of users
Provides the ability to exchange information in various forms(web pages, files,etc)
Accommodates different users with different browsers, applications, operating systems,etc
Allows users to join groups or administrators to assign identities in a controlled but simple fashion
Maintains integrity over time, regardless of administrative turnover, changes in technology or the increasing complexity of the corporate information system.
CONCLUSION
In order for businesses to receive the full benefits of intranets and Internet technology, a dynamic VPN needs to be implemented.
A dynamic VPN can establish trust in open environments and accommodate the information needs of a business in a flexible, a business with a dynamic VPN can provide access to more information and allow a greater range and diversity of communication, both within the company and among companies on the Internet.
