While these type of VPN services work, they are not very eco-friendly (you need a powered on PC for each remote user) and they don't support activities such as composing and reading mail when there is no internet access (such as on an aeroplane). Other VPN services connect the remote user to the office network as if their PC was on a very long cable.
Second, VPN is nearly impossible to tap or interfere data in the VPN tunnel. And lastly, a VPN client software can connect you to your company from anywhere around the globe. It also reduce operational costs, transit times and travelling costs for remote users. Global networking opportunities, telecommuter support and faster Return On Investment are provided as well, other than the use of traditional internet. Those who especially live in China, Europe, USA, Middle East and Africa will know what VPN actually is. For those who still do not know anything about VPN technology despite of it being one of the fastest growing technology and businesses on Internet.
Without the reliable communication capabilities of a VPN, companies wouldn't run so well. A virtual private network, or VPN as it is commonly known, is a network that uses a public telecommunication infrastructure to provide faraway offices or individual users with secure access to the network of their organization. A virtual private network can be compared with a system of owned or leased lines. A VPN is used to provide the organization with the same services but at a lower cost. A VPN can be described as one or more wide area network (WAN) links over a shared public network. Secure VPN technologies may be used to enhance the security of the private link. IPSec is comprised of 3DES encryption, IKE key exchange authentication and MD5 route authentication, which provide authentication, authorization and confidentiality. Internet Protocol Security (IPSec)IPSec operation is worth noting since it such a prevalent security protocol utilized today with Virtual Private Networking. IPSec is specified with RFC 2401 and developed as an open standard for secure transport of IP across the public Internet. The packet structure is comprised of an IP header - IPSec header - Encapsulating Security Payload. In addition there is Internet Key Exchange (IKE) and ISAKMP, which automate the distribution of secret keys between IPSec peer devices (concentrators and routers). Those protocols are required for negotiating one-way or two-way security associations. One such security measure is the use of SSL VPN for tunneling specific protocols,Secure socket layer virtual private network or SSL VPN is a Virtual Private Network, which extends as connection over the public Internet, enabling far away users to access corporate resources securely. SSL is an application level transport protocol that transmits data over a standard TCP port. Any client who has a network connection can make use of SSL VPN without the need for any additional client software. Also, Internet users do not need to remember the names or IP addresses of machines on the network. The most important one is that many remote users can access a network from anywhere in the world. It doesn't need a dedicated laptop or remote VPN site to access the network. In the window, look out for Internet Network heading and click "Network".
