3.1.4 - Identify the technologies required to provide a VPN. Flashcards
What is a VPN and how does it work?
A VPN (Virtual Private Network) uses the internet to allow people to log into a network remotely, accessing its resources while encrypting the connection to prevent eavesdropping.
Why are VPNs popular in supporting remote workers?
VPNs allow remote workers to securely access corporate resources like intranets, file servers, and email, making them popular in fields where privacy is crucial, such as health care.
What is encryption in the context of VPNs?
Encryption is the process of encoding data so that only a computer with the correct decoder can read and use it, ensuring data security during transmission.
What is tunnelling in VPN technology?
Tunnelling involves creating a logical network connection where VPN protocol packets are encapsulated within a base protocol, transmitted between the client and server, and then decrypted at the receiving end.
