The 2010 Data Breach Investigations Report covers a study conducted by the Verizon Business RISK team in cooperation with the United States Secret Service.

In some ways, data breaches have a lot in common with fingerprints. Each is unique and we learn a great deal by analyzing the various patterns, lines, and contours that comprise each one. The main value of fingerprints, however, lies in their ability to identify a particular individual in particular circumstances. In this sense, studying them in bulk offers little additional benefit. On the other hand, the analysis of breaches in aggregate can be of great benefit; the more we study, the more prepared we are to stop them.

Not surprisingly, the United States Secret Service (USSS) is also interested in studying and stopping data breaches. This was a driving force in their decision to join us in this 2010 Data Breach Investigations Report. They’ve increased the scope of what we’re able to study dramatically by including a few hundred of their own cases to the mix. Also included are two appendices from the USSS. One delves into online criminal communities and the other focuses on prosecuting cybercrime. We’re grateful for their contributions and believe organizations and individuals around the world will benefit from their efforts.

With the addition of Verizon’s 2009 caseload and data contributed from the USSS, the DBIR series now spans six years, 900+ breaches, and over 900 million compromised records. We’ve learned a great deal from this journey and we’re glad to have the opportunity to share these findings with you. As always, our goal is that the data and analysis presented in this report proves helpful to the planning and security efforts of our readers.
