In today's digital world, where we use the internet for work and important tasks, it's crucial to keep our data safe from cyber threats. An effective approach to achieve this is through the use of a VPN. In this blog post, we'll simplify the concept of a Virtual Private Network and illustrate how it plays a crucial role in safeguarding our information.
What does the term Virtual Private Network mean?
A Virtual Private Network (VPN) is a secure, encrypted connection established over the Internet between a device and a network. This encryption safeguards the transmission of sensitive data, preventing unauthorized individuals from intercepting the traffic. VPNs enable users to work remotely while maintaining the confidentiality of their communication. This technology is extensively employed in corporate settings.
What is the functioning mechanism of Virtual Private Network?
VPNs operate by directing a device's internet connection through a specifically configured remote server network managed by the VPN service. As a result, all data transmitted through a VPN connection is not only encrypted but also concealed behind a virtual IP address, providing the ability to safeguard your identity and location.
What are the advantages of using this private network connection?
VPNs offer numerous advantages for organizations seeking to facilitate remote work and connectivity for various sites, such as:
Secure Connectivity: VPNs establish an encrypted link between a remote user and the enterprise network, guarding against eavesdropping and minimizing the likelihood of the remote user contracting malware.
Simplified Distributed Networks: Whether it's a remote worker or a branch site, a user maintains an encrypted connection with the headquarters network through VPN. These connections offer a user experience closely resembling a direct connection to the headquarters network, simplifying the design and implementation of distributed networks.
Access Control: Prior to accessing resources on the corporate network, authentication is mandatory for a VPN user. This measure serves to safeguard against unauthorized access to corporate assets.
Data Throttling Prevention: By restricting outsiders' visibility into the data transmitted through the encrypted channel, a VPN aids in protecting against the throttling of specific types of network traffic.
Network Scalability: VPNs allow organizations to seamlessly connect dispersed networks over the public Internet through encrypted channels. This facilitates the effortless scaling of the network while treating it as a unified, private network.
What are the Disadvantages of using this private network connection?
The appropriate secure remote access solution offers substantial advantages to an organization, yet an ill-suited one can pose a significant liability. Several typical drawbacks of VPN solutions include:
Slow Connection Speeds: Authentication and connection setup are essential for VPNs, involving interactions between the remote user and the VPN server on the corporate network. This can result in sluggish connection speeds, and frequent session timeouts may necessitate repeated authentication.
Complicated Setup & Management: A VPN establishes a point-to-point connection connecting a remote user or site to the corporate network. This can lead to the development of an intricate network infrastructure that proves challenging to deploy, configure, and manage.
Poor User Experience: Certain VPN solutions pose challenges in terms of configuration and may lack robust support on specific devices and operating systems. This results in a suboptimal user experience, potentially leading users to inadvertently violate corporate policies.
Security Risks: A VPN is crafted to furnish a secure connection and unrestricted access to the enterprise network for a remote user. However, it lacks access controls or security inspection, leaving it without safeguards against compromised accounts, data exfiltration, malware, or other security risks.
What are the different types of these private network connections?
VPNs are designed to offer accessible security tailored for smaller-scale requirements. Here are a few instances of VPNs:
Cloud VPN: Deploying VPNs on virtual machines allows for "cloud-enabling" them, leveraging the hardware capabilities of a VPN while artificially incorporating cloud functionality, such as enhanced scalability and endpoint protection. While these may prove more beneficial for extended enterprises compared to a traditional standalone VPN appliance, they might still lack the flexibility to adequately support a remote or hybrid workforce on a larger scale.
Personal/Mobile VPN: Organizations like ExpressVPN and NordVPN provide VPN apps that users can download to ensure the security of their personal devices. This is a prudent precaution, especially when browsing the web on unsecured Wi-Fi networks. While certain free VPNs are accessible for safeguarding your devices, it's worth noting that they may transition to paid services over time.
Remote access VPN: Tailored for users operating remotely in a corporate environment, these are usually implemented within a company's data center. They can be extended, albeit at the expense of web and/or app performance, to shield remote users from malware and other threats. Their prevalence surged significantly in the wake of the COVID-19 pandemic.
