Interesting report from the Aberdeen Group
I agree that "Three ways of dealing with the issue come to mind: containerization of business data, user authentication, and data encryption".
We can follow the lead by credit card companies that establised PCI DSS for "containerization of business data, and data encryption" of sensitive data.
I recently read an interesting report from the Aberdeen Group that revealed that "Over the last 12 months, tokenization users had 50% fewer security-related incidents(e.g., unauthorized access, data loss or data exposure than tokenization non-users".
Nearly half of the respondents (47%) are currently using tokenization for something other than cardholder data The name of the study, released a few months ago, is "Tokenization Gets Traction".
Aberdeen has also seen "a steady increase in enterprise use of tokenization as an alternative to encryption for protecting sensitive data".
Modern data tokenization can also be used for containerization of business data.
