Feb. 5 — Risks associated with storing data in the cloud can be mitigated through the use of safeguards and a properly regulated framework, former Canadian Interim Privacy Commissioner Chantal Bernier said Feb. 4.
Speaking at the 17th annual Privacy & Security conference in Victoria, British Columbia, she said the cloud could be safe for data because it has proper encryption and is a zero-knowledge system.
That means the cloud can have no knowledge of the information it holds, Bernier said. However, she said a problem that cloud storage faces is that it is an abstract concept for many.
“Maybe we need to think differently,” she said, adding that accountability and transparency are needed.
Before resorting to cloud storage, a cost-benefit analysis must be done to determine if it is justified and if there is a need for broad accessibility to data, she said.
Benefits of cloud storage include:
According to Bernier, risks of cloud storage include:
Bernier said a good approach to dealing with cloud protections is ISO 27018—which “establishes commonly accepted control objectives, controls and guidelines for implementing measures to protect Personally Identifiable Information (PII) in accordance with” privacy principles for the public cloud computing environment.
“It is based on privacy not security,” she said.
