botCloud attacks - are cloud providers prepared?

When talking about cloud security, most people quite rightly think in terms of securing the data that they themselves are storing or accessing through the cloud. Quite often this is limited pretty much to the areas of authentication, encryption and regulatory compliance. Those with a little more understanding of the field may broaden the definition to include predictable availability and data recovery, application security and privacy issues surrounding e-discovery and physical access to datasets with an emphasis on logging and audit trails. The reason I have gone over old ground and stated the obvious is simple, there's one area of cloud security that is all too often overlooked with potential dire consequences: botCloud hosting.
