VPN
Definition
A Virtual Private Network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
Why It Matters
VPNs are used to create a secure, encrypted connection (a "tunnel") over the internet. This is essential for remote workers to securely access company resources, and for individuals to protect their privacy on public Wi-Fi.
Contextual Example
An employee working from home uses a VPN client to connect to their company's network. All their internet traffic is routed through the encrypted VPN tunnel, allowing them to access internal file servers and applications securely.
Common Misunderstandings
- A VPN does not make you anonymous; it hides your IP address from the websites you visit, but your VPN provider can still see your traffic.
- It protects your traffic from being snooped on by your local network provider (e.g., the coffee shop Wi-Fi).
