Abstract: In 2017, the US CYBERCOM was upgraded to the tenth Unified Combatant Commands, and its status was equal to the major combatant commands such as the US CENTCOM. This means that cyberspace has officially became the fifth battlefield of the US military after land, sea, air, and space. Countries such as Britain, France, Germany, Japan and Russia are also active in cyberspace. Cybersecurity has been attaching great importance around the world. Studying the policy direction of countries with leading cybersecurity technologies such as the United States has a good inspiration for researchers in China. In March 2018, the Department of Homeland Security released two new guides, Cyber Security Division Technology Guide 2018 and Cyber Security Division 2018 Portfolio Guide, which outline the range of products researched by the Science and Technology Directorate in the field of cybersecurity and promote the marketization of their products. This paper provides a brief introduction of the research directions and projects mentioned in these two guides.
