From the Presentation: " A renewed focus on supply chain risk management (SCRM) in the context of national security, its importance to the prosperity of the larger U.S. economy, and its entwined cyber threats, make SCRM a new and critical aspect of CISA [Cybersecurity and Infrastructure Security Agency] concern;  Increasing CISA is talking about SCRM as 'National Industrial Base Security' to allow for a precise conversation both on the nature of the evolving threat and how CISA means to adapt to protect the U.S.;  SCRM has historically been seen as the purview of the Department of Defense under The Defense Production Act and derived from that laws Title 3 authority;  This historic lens has focused much of the discussion about supply chain security around those industries and applications that held intrinsic defense applications and largely ignored the greater uses to society."
