Module 3: Understanding Concepts relevant to Cloud Computing

Question 1

What are the two key elements of Network Security?

Answer 1

1. Physical environment security ensures access to the cloud service is adequately distributed, monitored, and protected by underlying physical resources within which the service is built.
2. Logical network security controls consist of link, protocol, and application layer services.

Question 2

What is the network perimeter for the cloud?

Answer 2

1. For many cloud networks, the perimeter is clearly the demarcation point.
2. For other cloud networks, the perimeter transforms into a series of highly dynamic “micro-borders” around individual customer solutions or services.
3. In other cloud networks, there is no clear perimeter at all.

Question 3

Give three scenarios where the term “Data in Motion” or “Data in Transit” occurs.

Answer 3

1. Data transiting from an end user endpoint such as a laptop/smart phone etc. on the internet to a web-facing service in the cloud.
