What characteristic describes a VPN?
- software on a router that filters traffic based on IP addresses or applications
- a tunneling protocol that provides remote users with secure access into the network of an organization
- a network device that filters access and traffic coming into a network
- software that identifies fast-spreading threats
| Explanation & Hint:
A VPN (Virtual Private Network) is best described by a tunneling protocol that provides remote users with secure access into the network of an organization. A VPN allows users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks. It provides secure access because the connection is encrypted, which keeps the data transmitted over the VPN private. |
