Network Security

1. There are four types of VPN.

Name them and give an example of when I should use that type.

Do you think there will be the need for more types of VPN? Why?

2. How does software defined networking affect the management of a VPN in comparison to traditional VPN management?

Does it improve or does it not improve the management of a VPN?

3. As threats and attacks are a continuing issue, what new technologies/methods do you think should be implemented to protect a VPN?
