What does the acronym VPN stand for in the context of cybersecurity?

1. Virtual Private Network

2. Validated Personal Number

3. Virtual Public Network

4. Voluntary Private Node

The correct answer is: Virtual Private Network

In the context of cybersecurity, VPN stands for Virtual Private Network. A VPN creates a secure and encrypted connection over a less secure network, such as the internet. This allows users to send and receive data as if their devices were directly connected to a private network. By using a VPN, individuals and organizations can protect their online activities from eavesdropping, ensure privacy when accessing public networks, and bypass regional restrictions. The term "Virtual" indicates that the network is created through software, while "Private" signifies that the data being transmitted is kept secure and separate from other internet traffic. This combination is essential for maintaining confidentiality and integrity, especially when handling sensitive information. Other options, such as Validated Personal Number, Virtual Public Network, and Voluntary Private Node, do not accurately describe the established concept of VPN in cybersecurity. They either introduce terms unrelated to this field or inaccurately reflect the characteristics and functions of a VPN.
