Is cloud computing safe

From security side, cloud computing has lot of problems. So, in spite of giving so much facilities, it is not secured. Thus its not safe...

The cloud is vulnerable to attacks and data on the cloud is not secure. In a recent research paper published my MIT the cloud is vulnerable to "side-channel" attacks -- A side-channel attacker looks at indirect information related to the computer—the electromagnetic emanations from screens or keyboards, for example—to determine what is going on in the machine.

Researchers were able to pinpoint the physical server used by programs running on the EC2 cloud and then extract small amounts of data from these programs, by placing their own software there and launching a side-channel attack. Security experts say the attacks developed by the researchers are minor, but they believe side-channel techniques could lead to more serious problems for cloud computing.

Cloud Computing indeed has very positive sides in usage. But unfortunately, from security side, it is not yet secured....

I don't think cloud computing is safe. There are many secuirity issues associated with it. At the heart of cloud infrastructure is this idea of multi-tenancy and decoupling between specific hardware resources and applications. In the jungle of multi-tenant data, one needs to trust the cloud provider that your information will not be exposed.

For their part, companies need to be vigilant, An important measure of security often overlooked by companies is how much downtime a cloud service provider experiences. Exception monitoring systems is another important area which companies should ask their service providers about.

An important consideration for cloud service customers, is to find out about the hosting company used by the provider and if possible seek an independent audit of their security status.
