Abstract: Cybersecurity is currently receiving widespread attention from governments, academia, and enterprises around the world. The US Department of Homeland Security issued the Blueprint for a Secure Cyber Future in 2011, which defines 75 strategies that can strengthen national cybersecurity, 25 of which are key strategies. The Rand Corporation conducted research on the strategies proposed by the report and the effect of these strategies, analyzed the shortcomings of the DHS blueprint, proposed a method for assessing network security defense behaviors and produced a report A Framework for Programming and Budgeting for Cybersecurity. The report uses the sunburst to represent the main goals of cybersecurity, the four strategies that support the goals, and the specific strategies and activities. This paper will give a brief introduction to the research results of RAND.

Key words: cybersecurity, the USA, the RAND Corporation, security defense, security strategy
