Data stored on main servers involved in cloud computing is accessible from everywhere in the world and anyone can access to main servers, what will be the extra security measures to be taken to secure the sensitive data available at main servers for unauthorized use from persons or groups?

I heard that Cloud computing is a term where a company use the third party resources instead of running software's applications on local server or storing data locally. clouds are hundreds or thousands of computer connected via each other and shared by companies to host their application and manage data.

But I have some confusion about the security in a cloud environment, please expert clear me about my doubt, my questions are.

1. Is the data center where that computer is located staffed 24 hours a day, seven days a week? What staff is on-site?

2. Are servers dedicated to each customer, or do multiple customers share a single server?

Hi guys! Can anybody explain to me why I sometimes get this Security Warning dialogue box saying "You have requested an encrypted page that contains some unencrypted information. Information that you see or enter on this page could be read by a third party." I usually get this message whenever I am browsing through the internet.

I don't get it a lot, but it kind of makes me feel uncomfortable whenever I click on OK because as it says on the error message, there might be some information that I am entering on the website which could be ready by a third party.
