While data breaches are as common as any other daily occurrence in the business and individual worlds, the large security incidents don’t happen as often, especially if you think that one of the breaches in the top ten all time largest data exposures dates back to 1984. 2011 is not yet over and it already is the poster child of this top we all want to see unchanged.
2011 is the only year with three major data loss incidents in the top ten: Sony Corporation with 77 million records exposed, SK Communications, Nate, Cyworld with 35 million and again Sony Corporation through their Sony Online Entertainment division with close to 25 million records exposed. Luckily for us, although it featured large incidents, 2011 did not create as many victims as 2009 with its two incidents, Heartland Payment Systems, Tower Federal Credit Union, Beverly National Bank which share the number one position in the infamous top with 130 million records exposed and RockYou Inc. with another 32 million.
