An analysis of data breaches by Trustwave found just 9 percent were uncovered internally by the companies that were breached. The report mirrors other studies and underscores the importance of having visibility into your IT environment as well as being able to correlate disparate events on a network.
You might expect an enterprise to be the first to notice its records had been breached. But as a report from Trustwave illustrates, that is rarely the case.
According to a study of more than 200 data breaches that occurred in 2009, Trustwave found that just 9 percent were uncovered by the organization that was attacked. The vast majority—80 percent—were discovered by credit card companies with access to the breached organization’s data. According to security pros, the reasons for this vary, but it comes down to the ability of businesses to understand and correlate the massive amounts of data at their fingertips.
The Trustwave study echoes the findings of Verizon's "2009 Data Breach Investigations Report," which reported roughly 70 percent of breaches were found by third parties. To Avivah Litan, an analyst with Gartner, credit card companies have the most incentive to uncover breaches because if financial information is stolen they are often the ones that get stuck with the bill.
“When there is a breach against the retailer or processor, they don’t suffer direct losses; they only suffer losses after the card companies discover who they are and then force them to pay them back,” Litan said.
