Question:
How is "tunneling" accomplished in a VPN?
- New headers from one or more VPN protocols encapsulate the original packets.
- All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private.
- Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers.
- A dedicated circuit is established between the source and destination devices for the duration of the connection.
Explanation: Packets in a VPN are encapsulated with the headers from one or more VPN protocols before being sent across the third party network. This is referred to as "tunneling". These outer headers can be used to route the packets, authenticate the source, and prevent unauthorized users from reading the contents of the packets.
