In the day and age of digital technology extending from everything around extending even to our “digital well-being”, it’s not a surprise when someone’s private life is threatened. Something that used to be a joke has dug its hands in extortion and top level security breaches. As the general audience who thinks, “what’s there to lose” should also care about their passwords, messages, captured frames of their loved ones that internet safety is not something anyone should take lightly and this is how you can watch out and be a step ahead of people with malicious intentions and programs.
VPN, Virtual Private Network is hands down the best solution to all the problems. Your general surfing network is way less secure than you think. So, it creates, as the name suggests, a virtual connection through which your location is untraceable and gives you access to the domains that are not accessible in your area because of geo-restriction. VPN does it by encrypting the giving and receiving network addresses, a protocol called Tunneling protocol. Many people use VPN service to encrypt their location or access a geo-restricted domain. So, many people who care about privacy use the service for their benefit. One should make sure to choose the best VPN for the same.
How VPN works
In simple words, the process of working of VPN is that it creates a connection from point A to point B that is restricted or not available to unauthorized users. It creates a VPN tunnel and the process itself is called VPN tunneling where the endpoint device client uses a VPN service. Virtual Private Networks and not solely software oriented. There is also hardware VPNs which are more expensive but works on a more stable load of encryptions and data processing though mostly used by professionals and people with higher security threat.
Types of VPNs
- Remote Access VPN: Remote Access VPN connects to an organization’s network through a VPN gateway server. It’s generally used to get access to internal network resources like intranets, printers and file servers. It works on authentication of device’s identity for the access.
- Site-to-site VPN: Differing from the above, site-to-site VPN is used to connect a whole network in one location to a network in another location. Here, site-to-site VPN use a gateway device to achieve the connection. There is no need for VPN clients as the gateway handles the whole connection.
- Mobile VPN: In a mobile VPN, a VPN server enables a secure tunneled access through authorized VPN clients. The service, well, is not related to a physical IP address, rather it is related to a logical IP address that sticks to the mobile device where it doesn’t matter what the location is.
- Hardware VPN: Hardware VPN has practically more advantage than the generally used Software VPNs. However, they prove to be more expensive than the software ones. That is why; they are more feasible and practical for large businesses than small enterprises. Even though it’s hardware VPN, a Web Browser Interface manages the administration.
