According to a new report from KPMG International, data loss incidents, which affected more than one billion people in the last five years, have increased by 40 percent since 2011.

"The report, which looked at data from 82 countries, found that government, healthcare, education, financial services and retail comprised the top five worst performing sectors for data loss incidents in the last five years," writes The Nashville Business Journal's E.J. Boyer.

"The main cause of data loss in banks is hacking -- 35 percent of incidents in financial services in 2012 were in this category," writes American Banker's Penny Crosman. "Another 30 percent of incidents were caused by fraud and/or social engineering. Much smaller impacts were caused by hard copy loss or theft (8 percent) and human error (also 8 percent)."

"As expected, the use of mobile devices for business purposes has led to a significant rise in data loss threats," writes Softpedia's Eduard Kovacs. "Health care and professional services organizations, which maintain the largest databases of personal information, are responsible for losing the personal details of 18.5 million people in PC theft incidents alone. PC theft accounted for one third of the total incidents that marked these industry sectors in the first half of 2012."

"Hard drives continue to be the number one target for portable media data loss, but we have seen a big increase in incidents around DVDs and CDs, as well," KPMG LLP partner Greg Bell said in a statement. "The volume of company data stored on personal and mobile devices needs to be a major consideration when devising a comprehensive security plan."
