"This latest information and research ... suggests that organizations in all industries need to take note that they face a very real threat from security breaches. Whether it is the constantly increasing security threats, ever-evolving IT technologies, or limited security resources, data breaches and the costs related to response and mitigation are escalating quickly," the report said.
The study also revealed that hacking caused 33 percent of 2011 data breaches, accounting for 83 percent of all exposed information. Additionally, hacking surpassed stolen laptops as the most prevalent type of data breach, the report said.
