There are two issues with Cloud security. First of all, the security technologies that use Cloud are new elements and there is an interesting shift happening in the security industry. The companies provide more and more services that are based on Cloud technology and that's good news, because that makes the life of cyber criminals harder.

The second issue is that when the enterprise is government or businesses allocate data in the Cloud there is a serious security issue because when they keep it in-house or at end points, the company who owns that data is responsible for security. You own that and manage security for that. If the data is allocated in the Cloud than who is responsible for security?

The company which provides this service. If you leave your personal data in the Cloud who guarantees that no one else has access to that? There are many issues and unfortunately there are more incidents where Cloud services are hacked and it is leaked in a rain of data.

The hacking landscape is not the same. There are different cyber criminals who steal data to earn money or engage in cyber sabotage, such as those responsible for the Stuxnet worm. At the same time, there are hackers who only hack systems to learn. They don't damage the systems and just get inside to see the application work.
