Networking fundamentals with Virtual Private Networks (VPN)
What do you need to know about VPN networking?
For most of the organizations, Virtual Private Networks (VPNs) play a crucial role in achieving remote connectivity to break communication and employee productivity barriers. In previous years, the global VPN market has been reached more than 15 billion. It will steadily increase by 2022 by up to 35 billion. VPNs offer secure, low-cost connectivity to different remote networks and users. Also, it allows businesses to expand their workforce network on a global level without building physical workplaces in every other location.
What is VPN technology?
Virtual Private Networks is a networking technology that allows users to surf the web through an encrypted tunnel. VPNs connect your device to another computer known as a server. It is located in a different region and enables the user to access websites and other resources on the Internet. Based on the location of the selected server, users can hide their identity and access online resources that are restricted in their country.
What are the types of Virtual Private Networks?
In this VPN configuration, companies use a VPN gateway to send and receive TCP/UP traffic, in contrast to using VPN client software. The VPN gateway encrypts all the outbound traffic. Later, it passes through a VPN tunnel to another VPN gateway located at the destination site. The VPN gateway receiving the content packet removes the headers, decrypts it, and relays it to the destination host that is located in its private network.
In other words, site-to-site VPNs offer transparent network access to a third-party network or remote connection by establishing static connections.
Remote access VPNs
With the globalization of businesses, the owners have to resort to VPN software to facilitate the telecommuting and remote working activities of their employees. This type of network enables remote, securely access company data using the server architecture.
Why organizations need VPNs?
- Heightened Security – Nowadays, businesses utilize the online space in one way or the other. It makes them a potential victim for cyberattacks and security breaches due to insecure access to the Internet. VPN ensures that your employees do not expose their critical data using unsecured, public networks.
- Secured Telecommuting - VPNs have become important for business travelers that enable them to connect to the company’s network from remote locations in order to access the local network resources. This keeps the company’s data safe and off the grid from unsafe public networks.
- Cost-Effectiveness - When compared to a physical private network, VPNs have proved to be much more cost-effective. This is because the businesses have to lease long-distance connections to ensure secure data transfer.
Become a certified network professional for proficiency in VPNs
The high demand for VPNs has led companies in hiring certified network engineers of Top Engineering Colleges. They must be proficient in laying down the network infrastructure with integrated VPN support for its business users.
