Data Storage Disk Failure

QUESTION 1. At the airport, there is a risk of data storage disk failure (fire, smoke, or flood) which will also damage the disk backup in the Airport IT system data center. What can you do to reduce data storage disk failure?

QUESTION 2 It was decided to move Passenger Database to the cloud.  How can you provide Security for the Passenger Database? Here you should address the questions

1. a) Security Devices that access the Passenger Database
2. b) Security of Passenger Data -at-rest
3. c) End user security. Where the user would be accessing the Passenger Database from the airport

QUESTION 3 Assume that Passenger Database is already moved on the cloud side. And the airport has fast and reliable network connections.  If the cloud service provider devices fail to operate, then the Passenger Database would be not reachable (Loss of Control).  That will have a huge impact on Airport operations.

What would you do to Minimize Loss of Control, so the impact would be less?
