Providing a secure isolated account for cloud-based storage services

Abstract

Described is a system (and method) that provides a mechanism for guarding against cyber-attacks including ransomware, malware, and various other types of malicious attacks. The mechanism includes providing an isolated storage recovery account within a cloud-based storage infrastructure. The isolated storage recovery account secures data even in instances where credentials for a subscriber to a cloud-based service or the cloud-based provider itself is compromised. In order to ensure that data is still protected even when access credentials may be compromised (e.g. by a disgruntled employee), the mechanism requires a joint coordination between both the provider and the subscriber. The joint coordination may be mandated by the use of a particular multiple encryption technique for credentials that are required to access the isolated storage recovery account.
