Public networks are cesspools where sensitive data is often easily stolen, and your geographical footprint may even put you at risk of persecution based on the content you have been accessing through the internet – this is the case in a great many countries in the world. Additionally, a lot of content may be blocked for anyone accessing the internet from where you are. These are definite problems, whose single solution is to use virtual private network(VPN) connections. We will explain here what they are, and what softwares provide sound VPN connections for a safe and hassle free way to browse the internet.
VPN function resembles that of firewalls on your computer – much like firewall protects the data on your computer, VPN does the same thing online. Technically, a VPN is a Wide Area Network(WAN) but it retains the functionality, security and appearance of private networks. This has made VPNs very popular with private corporations who want secure remote access to the data on their servers using the internet, as well as individual users.
To make the virtual P2P connections, VPNs use both dedicated connections and encryption protocols, making the theft of data even more unlikely, as any data that is siphoned off in the unlikely scenario will be protected by encryption. VPNs also lets users hide their geographical footprints when accessing the internet, and this may be useful if content is blocked to you but is available for a person at a different physical location.

So how do we establish the VPN connection? This is surprisingly easy, and can be coalesced into the following simple steps. Your system first connects to the internet through ISP, as is usual, and then initiates VPN connection with the VPN server that is a part of company servers through client software. It is the client software that establishes the remote secure connection and grants the user access to internal servers. Secure yourself, get started with VPN right now.

There are many security protocols that are popular as VPNs and are commonly available. We list here the most popular with a brief description of their features:
1: IP Security/IPSec:
Predictably, it secures Internet communications, and has two modes of operation. The transport mode will protect the data packet message while the tunnel mode secures the entire data packet. For enhanced security, you should use this with other VPN softwares.
2: Layer2 Tunneling Protocol/L2TP:
The L2TP can not accomplish the encryption part, so all it does is generate the tunnel and IPSec ensures encryption, channel security and data integrity checks to ensure that all packets have arrived and none of them have been compromised.
3: Secure Sockets Layer (SSL) and Transport Layer Security (TLS) :
Used by online retailers and other such service providers. The two protocols use the so-called handshake method, where at the beginning of the session,the handshake produces the security parameters of the session including digital keys that help the two sides exchange encryption keys, authenticate the session and secure the connection against third-party attacks. To initiate SSL using http, users have to enter URL using https:// instead of http://
4:Point to Point Tunnelling Protocol (PPTP) :
This is one of the oldest VPN protocols available, and can be installed on a huge array of systems. Like L2TP, it does not do encryption but only tunnels and encapsulates data packets. It can be used in conjunction with protocols like GRE and TCP to also ensure encryption. This isn’t the strongest way to secure connection, but is still popular.
5:Secure Shell (SSH) :
This does both encapsulation and encryption of data, allowing users to direct traffic from remote unsecured file servers through an encrypted channel. The data will not be encrypted but the channel is.
The SSH tunnel will also allow you to bypass traffic from TCP port 80 to some other port on the local machine, which still connects to the remote server’s port 80. Hence, if the outgoing connections on the remote server work, the user can access the Internet, which would have been otherwise cut off.
Remember that to create VPN tunnels, you need VPN clients on your machine, something that Windows users have natively available on their machines. VPNs, thus, are super useful for a number of reasons and for a variety of users, and it is useful to know about the breadth of its features and the various protocols that help you set it up.
