Security experts are divided about last week’s decision by the U.S. Department of Justice to use Box for cloud-based document storage and collaboration. Putting potentially sensitive data into the cloud poses security and integration risks, some say. The biggest risk, he said, is coordinating an organizations’ security processes with those of multiple cloud providers. Box opted to store customer encryption keys in the cloud, instead of letting customers keep them on premises, behind the corporate firewall. The data that is stored is always in encrypted form, with nobody outside the organization having access to the keys.”]
