usefulness of Virtual Private Network

Virtual Private Network or VPN means a network technology capable of providing a connection secure network through a public network such as the Internet or another private network. Government agencies, large enterprises and educational institutions use VPN to allow remote users to connect safely and securely with a private network. Just like a WAN, a VPN is able to connect to multiple sites over long distances. Two techniques are obtained using VPN - 1) Signal Encryption makes the online activity of the user not found and 2) Handling of IP addresses

We discuss some uses of virtual private network below :.

1. public Wi-Fi Use with confidence : it is not clear at all that the Wi-Fi hotspots can be dangerous for private browsing and confidential emails. encryption security is not available to users with public wi-fi so it is vulnerable to hackers. Mobile users a public wireless access should therefore consider the services of a secure VPN connection. When all user logs in public wi-fi after connecting to a virtual private network, online activity is encrypted and hidden prying eyes
2. Get full access to Netflix and other blocked content :. Various streaming media providers have restrictions imposed on them in the content of the broadcast beyond the borders of a particular country. For example, Hulu, Pandora and Netflix are limited from broadcasting content outside the US. The location is plotted by finding the IP address of the user. Using the VPN service, IP address of the user can be manipulated as if he / she is in the US
3. Escape the restrictive network at school or at job. Because of the "acceptable use" policy associated with web browsing users in offices, schools, colleges and universities are blocked access to Twitter, Facebook, YouTube or any other website. A VPN connection allows the user to "tunneling out" the restrictive network and gives the user full access to restricted websites and webmail services
4. P2P files can be uploaded and downloaded in private :. P2P file sharing is totally disliked by the authorities due to financial and legal problems. A VPN connection is revealed to be the best friend of a user of P2P. A VPN connection can reduce bandwidth by 25% or more, but the IP address, the user loads and downloads will be encoded. This makes the user not found by the authorities. The risks of copyright lawsuits are avoided by using VPN
5. Internet Telephone calls may be veiled :. VOIP phone or internet can easily be spied. minors hackers can also spy on VoIP calls from the user. Regular users of VoIP services such as Lync, Skype or other voice chatting program should consider a VPN
connection
6. Judgment of search engines to connect the user to the research :. other search engines Bing, Google or make a list of all Web searches performed by the user. The online search information is attached with IP of the user to tailor future searches for the user's computer. This can lead to future public awkwardness. Therefore, a VPN connection is ideal for keeping the hidden IP user and maintain the confidentiality of research.
