According to the study, which looked at organizations crossing 17 different industry sectors, data breach incidents cost U. S. companies $202 per compromised customer record in 2008, up from $197 in 2007. The largest cost increase concerns lost business, showing a nearly 40% increase in the past three years. The average per incident costs in 2008 were $6.65 million, up from $6.3 million in 2007 and ranged from $613,000 to almost $32 million.
Healthcare and Financial Services Organizations Show Highest Losses.
No matter how comprehensive an
organization's information security practices are,
it is still vulnerable to a breach of confidential information. Healthcare and financial services companies have been shown to suffer the highest customer loss. The average cost of a healthcare breach is $282 per compromised customer which is twice that of the average retail breach of $131 per compromised customer.
Other key findings of the survey include:
- Third party organizations accounted for more than 44% of all cases.
- More than 88% of all cases involved insider negligence.
- Lost business is the most costly effect, averaging $4.59 million or $139 per record compromised.
- Data breaches experienced by "first timers" are more expensive than those experienced by organizations that have had previous data breaches.
- Training and awareness programs lead companies' efforts to prevent future breaches.
