Definition
A Virtual Private Network (VPN) is a technology for securely transmitting data through untrusted networks using encrypted connections.
Human Explanation
A VPN creates a protected communication channel between a user and an organisation's network or another system.
Why it Matters
Encryption reduces the Risk of data interception during communication over public networks.
Conceptual Boundary
A VPN protects data in transit but does not replace Authentication, Authorization or other security mechanisms.
Practical Perspective
A secure VPN connection should be combined with appropriate Authentication and Access Control.
