In this article, we’ll delve into the world of VPNs and explore their role in preventing cyber attacks.
Introduction to VPNs
A Virtual Private Network (VPN) is a service that creates a secure, encrypted connection between your device and a VPN server. This connection is often referred to as a “tunnel” because it encapsulates your internet traffic, making it difficult for third parties to intercept or eavesdrop on your online activities. By using a VPN, you can mask your IP address, location, and other identifying information, making it challenging for hackers to target you.
How VPNs Work
When you connect to a VPN, your device establishes a secure connection with the VPN server. This connection is encrypted using advanced protocols, such as OpenVPN or WireGuard, which ensure that your data is protected from interception. The VPN server then forwards your internet traffic to its final destination, making it appear as though the traffic is coming from the VPN server’s IP address rather than your own. This process is known as “IP masking” or “IP spoofing.”
