vpn tunnel

If you are not quite familiar to what virtual private networks are and how they work, you are missing out on probably the most innovative internet security measurement that exists nowadays. VPN services allow you to connect indirectly to the internet, as the connection is done through a VPN tunnel where all the data you send and receive is encrypted. Therefore, VPN tunnels can be seen as safe secure lines through which you can anonymously send and receive information to or from a public network, such as the WiFi spots in the airports or coffee shops. Such tunnels work similarly to the subway networks, as they transport packages of data from one point to another, in physically different places, through an encrypted connection. In the midst of public traffic, your usernames, addresses, messages and passwords are safely encrypted and protected against data fishing and interception.

VPN services also include a management protocol, which works as the gate keeper. Protocols open and close the tunnel whenever the VPN clients make such requests. Sending information via the VPN tunnel requires a special datagram based protocol that ensures that both end points have the same parameters, such as similar IP addresses, or data compression and encryption types. When establishing the virtual connection, the data packages are encrypted or encoded before they are transmitted through the VPN tunnel. Once they are received on the other end of the tunnel, they are eventually deciphered.

VPN tunnels fall under a few different categories. Compulsory tunnels are managed through networks carriers, which are responsible for establishing the authenticating, as well as associating them with the right VPN server. IPSEC on the other hand has the great capacity of being able to safely move the data packages across the public networks, treating them as mere cargo set for delivery. Hence, the VPN gateways function more like parcel services, as they are in charge of packaging and later writing the addresses where the packages have to be delivered.

There are 3 main protocols that are most commonly used by remote access virtual private networks. The first one is Point to Point tunneling protocol, or PPTP, the second one is Layer to tunneling protocol, or L2TP, while the last one is called Layer to Forwarding protocol, or L2F. All of these protocols were developed by Microsoft and Cisco in conjunction with the IETF. Each of them offers a different authentication schema and supports 40 – bit or 128 bit encryption.

Virtual private networks and their corresponding tunnel applications are meant to guarantee secure encrypted data transfers through the internet from one point to another. VPN clients are safe from snooping and hacking, which is the best benefit of using a VPN provider when accessing public networks and sending or receiving sensible data. VPN services are also used in homes and workplaces, as they allow the users to keep surfing the internet without worrying about any kinds of security threats. Lastly, they are used in corporate environments, allowing managers to easily monitor the business and safely access the network from other places.
