The cyberspace is rife with cyber threats which make vulnerable systems and networks their prime targets, taking advantage of their weak security measures and exploiting these systems’ users’ privacy. Every person that browses the web requires and expects online security and privacy. To digress, every website is hosted on the leased web server of a web hosting company. These companies are often referred to as the “Best Website Hosting in India” or as the “Best Windows Hosting Company in India” or as the “Best Cloud Hosting Company” when these offer the best quality of web hosting service in a particular country, such as in India in this case.
There are many websites that can be a threat to their visitor’s privacy and security. In this context, a VPN (Virtual Private Network) is a boon that fulfils this essential need. It provides its users online privacy, security as well as anonymity when browsing the Internet.VPN is the acronym for Virtual Private Network and it is meant to provide its users privacy and anonymity when they browse the Internet. It encrypts a user’s internet traffic and his online identity.
VPN encryption is an essential way to ensure a safe web browsing experience as it enables the user to protect his confidential data from cyber criminals, who cannot make sense of and hence cannot use the encrypted data. It also ensures a user’s privacy by making sure that the Internet user’s browsing activity cannot be monitored by governmental agencies, the Internet Service Provider (ISP) and/or by any advertising agencies. This helps to evade any censorship enforced by the government with regard to Internet browsing. Additionally, it helps to evade Google’s tracking. With VPN encryption facility certain restrictions, such as geo-blocking, can be easily bypassed. It helps to provide a secure usage of public Wi-Fi. These are few of the many benefits that VPN encryption offers. Greater control over privacy, user’s web surfing security and anonymity are assured by VPN encryption, which is the prime reason for VPN’s popularity and usefulness.
VPN encryption functions by securing the data in the channel that connects the VPN client to the VPN server, to ensure prevention of its exploitation by any third party. Every time the user runs a VPN client and connects to a VPN server, the connection request is encrypted before it is sent to the server. Next, it is decrypted by the server and forwarded to the Internet. The requested data is encrypted once again at the time when the server receives it and before it’s sent back to the user’s device that is connected to the Internet. The received data is decrypted by the VPN client, in order for it to be viewed and comprehended. VPN encryption entails encryption keys, encryption algorithms, VPN encryption ciphers, VPN encryption protocols, handshake encryption, HMAC authentication, Perfect Forward Secrecy.
In this context, a user needs to ensure that he or she has a long encryption key, which is at least 128-bit in size; reliable key exchange protocols, such as ECDH or RSA-2048; strong VPN ciphers, such as AES, Two fish, or Camellia; powerful VPN encryption protocols, such as Open VPN, Soft Ether, and IKEv2; a SHA-2 cipher for HMAC authentication (ideally 256-bit, 384-bit, or 512-bit) and Perfect Forward Secrecy features.
When it comes to VPNs, there is a catch. Not all VPNs provide data encryption. This is usually the case with free VPNs, which claim to offer encryption but don’t secure the user’s data at all. In the event where free VPNs actually provide encryption, it will entail a weak cipher, a small encryption key and less secure VPN encryption protocols like PPTP and L2TP. These offer no real encryption value on their own unless these are paired with IPSec. Moreover, with free VPNs there is a greater possibility of having a poorly-configured VPN encryption, which increases the likelihood of encountering cyber crimes by the users of free VPNs. Hence, it is always advisable to opt for a paid VPN service that is provided by a reputed and reliable service provider to enjoy the perks of a safe web browsing experience where one’s privacy never gets compromised.
