What does the acronym VPN stand for in network security?

The acronym VPN stands for Virtual Private Network. This technology creates a secure and encrypted connection over a less secure network, such as the Internet. By using a VPN, users can safeguard their online activities and ensure their privacy. It enables them to send and receive data as if their devices were directly connected to a private network.

Using a VPN is particularly beneficial in environments where sensitive data is handled, as it helps protect against eavesdropping and cyber attacks. Additionally, VPNs can allow users to access region-restricted websites by masking their IP addresses, effectively altering their perceived geographic location.

The other options do not reflect the correct terminology or functionality associated with VPN technology. For instance, "Virtual Protected Network" and "Variable Protected Network" do not accurately convey the core essence of the technology, while "Virtual Policy Network" suggests a completely different concept within network management or policy enforcement rather than secure communications. Hence, "Virtual Private Network" is the established and widely recognized term in the context of network security.
