What is a VPN can do for you
the concept of VPN is related to the safety and security on the internet. The VPN allows you to use a public network like the Internet in a way that can be used as a private network. The use of VPN is unlikely that our information will be captured by outside intruders. A VPN is what allows the connection with the network of a company by isolated individuals or offices in a safe and secure manner. It is until the late 190s that the concept of leased lines has been applied to the cause of connecting computers on a network.
Before the advent of VPN business houses has spent many hundreds of thousands of dollars to set up private networks that were difficult to apply generally known as Intranets . These networks do not come cheap and there were preparations made to use the technology of leased lines, Frame Relay and ATM to make the practical requirements for remote users. Previously, remote access servers called ISDN were used to connect to remote employees. Companies that do not have sufficient financial resources were required to accept a low speed dial-up services. Because increased bandwidth capabilities and the concept of the internet has become more popular among people in the technology people have started making the Extranets exist. However, we can not do without the Internet these days we keep nagging about the problem of Internet security.
The VPN uses twin concepts of tunneling and encryption to maintain the integrity and security of data. Because private leased lines services are not used in the VPN technology VPN massive cost less compared to the old technology. The use of VPN is hassle free and is still at a reasonable price. By using VPN technology team associated with an assignment, business partners and all remote offices can be connected from the organization's network at very low cost. There are cost savings in a variety of areas such as long distance charges, fees for leased lines and equipment lines. The concept of a tunnel VPN makes it really private because in the case of a VPN, even if you are online, you are safe against hackers and spammers who live on the Internet. In reality, you are on the corporate network.
Although the concept of a tunnel gives us the idea of a fixed path, it is not really the case. Only recipients of your message communicated can access your information. tunneling technology encapsulates network protocols within the IP thus keeping you anonymous. Encryption is actually a technique for coding and decoding of your valuable information. In the last parts of the tunnel or sit hardware and software which encrypts information while leaving and entering the computer. The information is encoded into cipher before the information leaves the computer for the tunnel. Upon receipt of the computer on the other side decrypts the return message in clear text.
