Virtual Private Network
A Virtual Private Network (VPN) is a technology that creates a secure, encrypted connection over a less secure network, typically the internet. It allows users to send and receive data as if their devices were directly connected to a private network, enabling secure remote access and protecting privacy by masking IP addresses and encrypting traffic.
Developers should learn and use VPNs when working remotely to securely access corporate resources, testing geo-restricted applications, or protecting sensitive data on public Wi-Fi. It's essential for implementing secure communication channels in distributed systems, ensuring compliance with data protection regulations, and safeguarding against eavesdropping or man-in-the-middle attacks in untrusted networks.
