ACKNOWLEDGMENTS Trent Nelson, Project Manager, Idaho National Laboratory; May Chaffin, Cyber Researcher, Idaho National Laboratory iii iv EXECUTIVE SUMMARY The U.S. Department of Homeland Security (DHS) National Cyber Security Division’s Control Systems Security Program (CSSP) performs cybersecurity vendor assessments, ICS-CERT operations, and asset owner cybersecurity evaluations with the Cyber Security Evaluation Tool (CSET) evaluations for industrial control systems (ICS) to reduce risk and improve the security of ICS and its components used in critical infrastructures throughout the United States. ICS differs from other computer systems because of legacy-inherited cybersecurity weaknesses and the significance of the impact of potential exploitation to the U.S. In 2009,a report titled “Common Cyber Security Vulnerabilities Observed in DHS Industrial Control Systems Assessments” compiled common vulnerabilities identified during 15 security assessments of new ICS products and production ICS installations from 2004 through 2008. Three additional ICS product assessments were performed in 2009 and 2010. This newer, 2010 version is an update to the 2009 version and has been developed to proactively create greater awareness within the ICS community.
