Question
What is the name of the technology that provides a secure
and encrypted connection over an untrusted network?Solution
A VPN (Virtual Private Network) establishes a secure, encrypted tunnel between a user’s device and the internet, protecting sensitive data from hackers and third parties. It allows remote users to securely access a private network over a public network (such as the internet), ensuring privacy and security.
- Proxy servers only mask IP addresses but do not encrypt data. - Sandboxing isolates suspicious applications to prevent system infections.
