Data loss cost companies $6.6 million per breach
Customers lose faith in organizations that cannot keep data safe and take their business elsewhere; study of data breaches show that negligent companies lose on average more than $6 million per breach
The total average cost of a data breach last year reached $202 per record, a 2.5 percent increase since 2007, a study published yesterday revealed. The study was conducted by the Ponemon Institute, a privacy and data-protection research group, and PGP, a data-encryption vendor. It was based on the costs incurred by 43 organizations following actual data breaches.
InformationWeek’s Thomas Claburn writes that according to the report, the total average cost per company surveyed was more than $6.6 million per breach, up from $6.3 million in 2007 and $4.7 million in 2006. The highest reported total cost among the 43 respondent organizations was $32 million. Of the average $202 per record cost, $139 was attributable to lost businesses as a result of the breach. As a percentage of the total cost per record, that represents 69 percent, which is up from 67 percent in 2007 and 54 percent in 2006. Customers, it seems, lose faith in organizations that can’t keep data safe and take their business elsewhere.
“This finding reinforces the message delivered by leading enterprise IT managers and industry analysts that organizations must focus on proactively protecting their data instead of relying exclusively on written policies, procedures, and training,” the report says.
Organizations should note the finding that third-party data breaches have become more common and that they cost more than internal breaches. Breaches that originated with outsourcing companies, contractors, consultants, and business partners accounted for 44 percent of the breach total, up from 40 percent in 2007. Third-party breaches cost an average of $231 per record, compared with $179 for breaches originating from within the organization that owns the data.
At the same time, it is insider negligence which is the biggest cause of breaches. According to the study, more than 88 percent of the breaches studied in 2008 arose from an insider’s mistakes. At least such breaches tend to be less expensive, at $199 per record, than breaches arising from malicious acts, at $225 per record.
In terms of preventive measures, the top three employed by respondents were training programs, additional manual procedures or controls, and the expanded use of encryption. PGP, as it happens, sells encryption products and services to businesses.
Claburn writes that encryption, long viewed as more trouble than it was worth, may finally have become a necessity. Heartland Payment Systems, which in mid-January disclosed a potentially massive data breach that could affect more than 100 million accounts, said just last week that it was accelerating its effort to deploy end-to-end encryption to protect its transaction data. Better late than never, but pre-breach deployment would have been better still.
