Premera Blue Cross, a major provider of healthcare services, is one of the latest victims of a long line of data breaches coming to light. The attackers didn’t get away with credit and debit card information per se. Still they obtained enough sensitive information that pairing it with financial information stolen from other breaches opens the door to identity fraud. This is why any data breach should be viewed as critical. It also illustrates why it is important to properly secure all data of a personal nature no matter how insignificant that data may seem.
The frequency and size of the recent barrage of data breaches, including one against a major global e-Commerce marketplace that compromised an estimated 80 million global records, might lead one to believe that user authentication, and other technology surrounding network security, is severely flawed. That belief would be in error. Instead, user authentication must be made foolproof.
Were Sherlock Holmes engaged to look into the epidemic of data breaches, his first admonition might be reprised from The Hound of the Baskervilles, “The world is full of obvious things which nobody by any chance ever observes.”
