Three major risks of Cloud computing

Global services firm Ernst & Young says the three major risks for companies investing in the Cloud include data leakage, the loss of data visibility and unauthorised access to data

IT professionals looking to place data in the Cloud should be aware of three major risks, including data leakage, the loss of visibility or control of the data, and unauthorised access to data, according to global services firm Ernst and Young.

The firm’s senior manager, Pieter Danhieux, told attendees of IDC’s Cloud for Business Conference 2011 that while Cloud service providers are often talking about scalability, availability, cost reductions, efficiency and effectiveness, they had not addressed Cloud security as a business enabler.

According to Danhieux, data leakage is of the biggest concern for IT managers and CIOs, as Cloud often uses virtualisation, entailing hypervisors and virtual systems.

“One of the risks that exist here is you want to remove some data you’re your system because it might not be relevant anymore, you send a command through the hypervisor to delete it… Anyone with a little bit of IT background knows that if you delete data from a disk it’s not actually deleted, the index to that certain location on the disk is deleted but the actual data is still there,” he said.
