Found this link on one of the security mailing lists I peruse. You can find an archive of the original post here. Here is the link:
A Chronology of Data Breaches Reported Since the ChoicePoint Incident
This should be of interest to not only DBAs, but also system administrators, managers, HR personnel, etc. There are many ways data can be breached... it's not just an insecure database. Quite a few of these are equipment related (stolen backup tapes, stolen laptops, etc.) which underscore the human element. This is further reinforced by the incidents where fraudsters and scam artists have been to penetrate systems, usually through social engineering. Security isn't just a technology solution. It also has to include people solutions.
