Do your security homework before storing big data in the cloud

From TechRepublic

"A majority of big data originates beyond enterprise walls and systems of records (SOR). This data streams in from corporate websites; it emanates from machines and sensors; and in still other cases, it's captured from the internet. Since so much internet and Internet of Things (IoT) data enters the enterprise from the outside, sites increasingly will look to public cloud providers to assist in the capture, exploitation and safety of this data. This makes data security a central concern.

Security and governance are still largely discussions for SOR data, but they should also be discussed for unstructured payloads of big data. If cloud services providers are storing this data, IT should be evaluating these providers' security practices, in addition to the providers' data storage, preparation and analytics capabilities.

‘The first questions that CIOs ask us is where their stored data is located, whether we have global data centres, and if the data centre that their data is being stored at is local to them,’ said Beth Weeks, senior vice president of engineering at Zilliant, which specialises in B2B sales analytics. ‘CIOs also want to know what the data centre's security and compliance policies are.’

There are layers of security questions beyond this, such as what the flows of the data are into the cloud service, and from the cloud service to the enterprise. ‘Data encryption is a frequent topic of discussion,’ said Weeks. ‘Enterprises want to know that their data is protected, that it is encrypted when it is at rest in the data centre, and that data is encrypted whenever it is sent and received.’”
