For large corporations, the name hackers send chills down the spine. Ordinary internet users may not see this as a big deal since most of their daily activities do not involve a lot of financial or confidentiality risks. This issue brings us to the VPN concept, but what is a VPN? Most of us know that a VPN hides your identity on the internet but do not understand how it works and why it matters when it comes to issues requiring internet privacy. Many VPN providers exist today to provide for the needs of individuals or organizations that require full protection of their sensitive online transactions.
Concept of VPN
VPN in simple terms is the implementation of a Wide Area Network on the internet so that security on a client-side machine extends to the server side machine. The process involved thus helps in transferring data between two private networks that are distant through a public network. There are two major types of virtual privates networks namely the IP Security (IPsec) and Secure Sockets Layer (SSL).
Encryption Levels of VPNs
Implementation of security features over a VPN connection can be done in two levels referred to as symmetric-encryption or public-key encryption. The public-key cryptography utilizes a public-private key pair for each computer in the network. The private-key encrypts a message at one end, and the public key decrypts the same message at the other end. For symmetric-key encryption, all computers in the network share the same key to encrypt and decrypt a message.
Role of VPN in Secure B2B transactions
Through the virtual network architecture is hidden and cannot expose data packets to be modified before reaching the end user, the VPNs play four significant roles in the B2B transactions. These functions of VPN include anti-replay, authentication, confidentiality, and Integrity. They all involve protection from modification of data packets, connection to real sites, protection from third-party viewers and preventing loss of data during transmission.
Benefits of VPN in Business
VPNs have more advantages compared to other conventional Wide Area Networks. Considering the money you would spend on a VPN against WAN, the ratio is too big. This high cost is mainly due to the infrastructure. When it comes to security, VPNs provide better protection than WAN because of the various protocols it implements such as Onion Service Protocol in TOR. Online anonymity is the other merit of VPN in that you cannot be easily identified on the internet.
Why use VPN for your Business?
Every business is a source of our income and there is a need to protect sensitive data from reaching the hands of our competitors. Spies caused companies to lose its secrets codes in the past and ended up having tough rivals who outdid them by producing better products using their codes. With VPNs, you can secure you data from leaking to hackers who constantly eavesdrop at you activities to collect the secret information from you. Stay anonymous by hiding your location with VPN.
The future of VPN Services and The closing statement
At the moment, demand for VPN is high due to concerns concerning the selling of private data by companies raised by the people. This trend has been predicted to progress to the future where more sophisticated tunneling services will be introduced to curb the menace at hand. Anonymity tools like Tor will also grow in demand as more users are looking for protection against spoofing, government interference, data collection, social attacks, data replays, etc. We all look forward to that day when the internet will be truly free.
