What does the acronym "VPN" stand for in network security?

The acronym "VPN" stands for "Virtual Private Network." A VPN creates a secure and encrypted connection over a less secure network, such as the Internet. By establishing a VPN, users can send and receive data as if their devices were directly connected to a private network, which enhances security and allows for safe data transmission even over public networks.

This encapsulation and encryption ensure that data remains confidential and protected from eavesdropping, making it a crucial technology in network security. Moreover, VPNs can facilitate remote access for users to connect to their organization's network from anywhere while maintaining the integrity and confidentiality of their communications.

The other options do not accurately describe the widely understood concept of VPN. "Virtual Personal Network" and "Virtual Public Network" do not reflect core features associated with VPNs, and "Virtual Protected Network," while somewhat relevant, isn't the industry-standard terminology. Thus, "Virtual Private Network" is the correct designation that encapsulates both the functionality and purpose of this network security technology.
