What's New About Cloud Computing Security?
While the economic case for cloud computing is compelling, the security challenges it poses are equally striking. This paper strives to frame the full space of cloud-computing security issues, attempting to separate justified concerns from possible over-reactions. The paper examines contemporary and historical perspectives from industry, academia, government, and "Black hats". It argue that few cloud computing security issues are fundamentally new or fundamentally intractable; often what appears "New" is so only relative to "traditional" computing of the past several years. Looking back further to the time-sharing era, many of these problems already received attention.
