How does a VPN (Virtual Private Network) enhance security?

A Virtual Private Network (VPN) enhances security primarily by creating an encrypted connection over a less secure network. This means that any data transmitted between the user’s device and the VPN server is protected from interception. Encryption ensures that even if someone is able to access the data being transmitted, they will be unable to understand it due to the encryption protocols used, such as AES (Advanced Encryption Standard).

This is particularly important when using public networks, such as those found in cafes or airports, where the risk of data interception is higher. By encrypting the data, a VPN helps protect sensitive information such as passwords, credit card numbers, and personal details from potential cybercriminals.

Other options, like limiting access to specific websites or providing a public Wi-Fi connection, do not contribute to enhancing security in the same way. Monitoring software updates might improve security indirectly by ensuring systems are up-to-date; however, it does not address the immediate need for securing data in transit, which is the primary function of a VPN.
