From the Executive Summary: "On February 24, 2021, President Biden issued Executive Order (E.O) 14017 on 'America's Supply Chains', which directed a whole-of-government approach to reviewing risks in, and strengthening the resilience of, supply chains supporting six industries that are critical to U.S. economic prosperity and national security. As part of this comprehensive review, E.O. 14017 directed the Departments of Commerce and Homeland Security to conduct a one-year assessment of the supply chains for critical sectors and subsectors of the U.S. information and communications technology (ICT) industrial base as defined by the respective agencies. In response, the Departments of Commerce (DOC) and Homeland Security (DHS) have prepared the following assessment of the supply chains supporting communications hardware, computing and data storage hardware, end-user devices, and critical software including open-source software and firmware. [...] The following assessment evaluates the current supply chain conditions for select hardware and software products, identifies key risks that threaten to disrupt those supply chains, and proposes a strategy to mitigate risk and strengthen supply chain resiliency."
