VIRTUAL PRIVATE NETWORK Introduction Along with the rapid development of internet, there is an increasing demand to connect to internal networks from remote sites. When employees work from home or go on business trips, they want to connect to the internal private networks of their companies over a secure connection. The demand of secure connection to internal network led to the technology of virtual private network A VPN is a private network technology that provides a way of protecting information

the technology VPN (Virtual Private Network) has established strong recognition among IT people and every administrator is committed to organize VPN-channels for employees working outside the office. Virtual Private Network is an association of individual machines, or virtual LAN network, which ensures the integrity and security of data transmitting. It has the properties of a dedicated private network and allows data transfer between two computers via an intermediate network such as Internet. VPN

Introduction There is a growing need to connect to internal networks from locations other than the regular and secure office. Employers and organizations need to realize that employees often need to connect to internal private networks from home, hotels, airports, etc. A solution for this problem is using a virtual private network (VPN), which is a network that uses public network paths, but maintains the security and protection of private networks. Secure communication is expensive, but VPNs allow organizations

concept of virtual private network. Virtual private network enables remote connections without the need of cables or leased wires. It leverages the capability of public network(i.e. the internet) to provide remote connections between different sites globally. Further, the report introduces the scope and objectives of Design Sheet metal private limited, the organisation which is trying to expand its operations throughout the Australian continent. The report proposes the implementation of virtual private

What is a Virtual Private Network? A virtual private network (VPN) is an addition of a private network that bridges the connection between a shared or public network. It allows you to send data between two computers in a point to point private link (Microsoft, Virtual Private Networking: An Overview). VPN allows individuals and companies to connect two locations securely and remotely. For example, if one company branch is in Secaucus, NJ and the other is in Newark, NJ; they can securely access

What is VPN? A Virtual Private Network (VPN) is a network constructed by using a local public network to connect to a private network. The invention of VPN and the main approach behind this has changed the world over the last decades. This network was initially created by many big companies and other organizations, but it wasn’t created for the end users. The main motive behind this technology was that the different companies wanted their network to be secure and private and also they also wanted

Virtual Private Networks Virtual Private Networks (VPNs) are an easy and cost effective way to connect two or more networks over the Internet. This is achieved by using encrypted tunnels for security and efficiency. VPNs use encapsulated and encrypted IP packets and transport them across leased Local Area Network (LAN) lines. The benefits of using VPNs are reduced cost overhead, reduced management overhead, and added security (Microsoft Press, 2000). Least network lines are expensive

Introduction A virtual private network (VPN) is a private network that extends across a public network, same as the Internet. It allow user to send and receive data across networks that can be either shared or public as if it’s their own device were connected on private network. Application running across VPN have functionality, security, management of the Private network. VPN allow employees to securely access a corporate intranet while located outside the office site. They are used for geographically

clear: Although large companies have the capitals and needs for building private networks, small and medium companies could rely on the less expensive, packet switched X.25 network. As the size of the Internet continued to grow, both small and large companies began to connect their private network with the public network. This brings a convenience but with one obvious problem – privacy and security. Virtual private network (VPN) was developed in 19XX by Stan Hanks, who build IP VPN based on TCP/IP-over-X
