Explanation
A VPN is a type of network technology that creates a secure encrypted connection between a device and a network. This connection allows users to communicate with each other and access network resources as if they were on the same local network, even if they are in different locations (see ISC2 Study Guide, chapter 4, module 3). A VLAN (Virtual Local Area Network) is a network segmentation technology that allows devices on a network to be logically grouped, even if they are in different locations. Firewalls are network security systems that control incoming and outgoing network traffic according to predetermined security rules. Finally, a router is a networking device that forwards data packets between computer networks, but does not provide the same level of security as a VPN.
