What is a VPN and what is one benefit and one risk of using one?

• A. A Virtual Private Network creates an encrypted tunnel for private network communication; benefit: privacy and access to restricted resources; risk: potential trust issues with provider and possible slower speeds.
• B. A tool that blocks pop-up ads in the browser.
• C. A protocol for email security.
• D. A service that stores cookies longer on your device.

Answer: (A)

A VPN is a Virtual Private Network that creates an encrypted tunnel between your device and a VPN server, so your data stays protected as it moves across networks and your real IP address is hidden from sites you visit. The main benefit is enhanced privacy and the ability to access resources that may be restricted by location, since your traffic appears to come from the VPN server rather than your device. A key risk is that you must trust the VPN provider with your traffic, and some providers may log data or misuse it; plus the extra routing and encryption can slow down your connection.
