The White House’s National Security Presidential Memorandum, NSPM-12 is explicitly focused on cybersecurity governance for national security systems, but many of its requirements depend on agencies having trusted, governed, and timely access to data about systems, policies, incidents, metrics, risks, and operational responsibilities. To implement the memorandum effectively, agencies need more than isolated security controls; they need a governed data foundation that helps them understand their environment, coordinate across agencies and mission partners, enforce policy consistently, and support mission-critical decisions.
