Negligent Employees and Malicious Attacks Cause 75% of Data Breaches
The past year was a whirlwind of high-profile data breaches. There were nearly 900 data breaches in 2011, more than the prior two years[i], with over 31 million records breached[ii]. And, as the number of reported breaches continued to rise, organizations still paid a hefty cost for data breaches, according to this year’s Cost of a Data Breach Study. The organizational cost of a data breach was $5.5 million last year, and the cost per lost or stolen record was $194.
Let’s dive into some of the more interesting findings from this year’s study.
Malicious Attacks Most Costly Breaches
Malicious or criminal attacks are causing almost as many breaches as negligent insiders. In 2011, negligence was the root cause of 39 percent of the data breaches, while malicious attacks caused 37 percent of data breaches (up 6 points from 2010). For the first time malicious attacks account for more than a third of breaches; they also remain the most costly type of breach at $222 per compromised record.
