The security gaps in cloud computing demand greater scrutiny than traditional IT outsourcing models, a new Forrester report says.
With traditional outsourcing models, a customer places its own servers in someone else's data center, or a service provider manages devices dedicated to that customer. But multi-tenancy rules the day in cloud computing, and customers may not know where their data is stored or how it's replicated, Forrester analyst Chenxi Wang writes in a report titled "How secure is your cloud?"
"Cloud computing decouples data from infrastructure and obscures low-level operational details, such as where your data is and how it's replicated," Wang writes. "Multi-tenancy, while it is rarely used in traditional IT outsourcing, is almost a given in cloud computing services. These differences give rise to a unique set of security and privacy issues that not only impact your risk management practices, but have also stimulated a fresh evaluation of legal issues in areas such as compliance, auditing, and eDiscovery."
