Usefulness of Virtual Private Network
Virtual Private Network or VPN signifies a network technology capable of providing secured network connection through a public network like the internet or some other private network. Government organizations, large corporations and educational institutions use VPN to allow remote users to safely and securely connect with a private network. Just like a WAN, a VPN is capable of connecting to multiple sites over long distances. Two technicalities are achieved by using VPN – 1) Encryption of signal which makes online activity of the user untraceable and 2) Manipulation of IP addresses.
We discuss some uses of virtual private network below:
- Use Public Wi-Fi with confidence: It is not known to all that Wi-Fi hotspots can be unsafe for private browsing and confidential emails. Encryption security is not offered to the users by public wi-fi and it is therefore vulnerable to hackers. Mobile users accessing public wireless therefore should consider the services of a secured VPN connection. When any user logs into public wi-fi after connecting to a VPN, the online activity is encrypted and concealed from snooping eyes.
- Gain full access to Netflix and other blocked contents: Various providers of streaming media have restrictions imposed on them in broadcasting content beyond the borders of a particular country. For example, Hulu, Pandora and Netflix are restricted from broadcasting content outside USA. The geographical location is traced by finding the IP address of the user. By using the services of VPN, the IP address of the user can be manipulated as if he/she is located within USA.
- Escape the restrictive network at school or at work: Due to the “Acceptable Use” policy associated with web browsing users at offices, schools, colleges and university are blocked from accessing twitter, Facebook, Youtube or any other website. A VPN connection enables the user in “tunneling out” of the restrictive network and gives the user complete access to restricted webmail services and websites.
- P2P files can be downloaded and uploaded privately: P2P file sharing is utterly disliked by the authorities due to financial and legal issues. A VPN connection proves to be the best friend of a P2P user. A VPN connection may reduce the bandwidth by 25% or more but the IP address, uploads and downloads of the user will be encoded. This makes the user untraceable by authorities. The risks of copyright prosecution are averted by using VPN.
- Internet telephoning calls can be cloaked: VOIP or internet telephoning can be easily spied on. Juvenile hackers can also eavesdrop on the user’s VOIP calls. Regular users of VOIP services such as Lync, Skype or any other voice chatting program must consider a VPN connection.
- Stopping search engines from logging the user’s searches: Bing, Google or other search engines make a list of all the web searches performed by the user. The online search informations are attached with the user’s IP to tailor the future searches for the user’s machine. This can lead to future public awkwardness. Therefore, a VPN connection is ideal for keeping the user’s IP hidden and maintain the privacy of the searches.
