> What are the most likely vectors of information disclosure or alteration in the cloud? Is it Ninjas descending on us-east-1a to steal the hard-drives your data is stored on? Why doesn't AWS use full disk encryption everywhere, such that the ninjas would find only random-looking data once they plugged the drives into the machines back at their base? Arguably people wouldn't want to pay the financial and performance cost for this security if they are just hosting publicly downloadable files in their S3 buckets, but I would hope that the cost would be negligible these days.
