The drafting, negotiation, and passage of the National Defense Authorization Act (NDAA) is an annual event that sets the annual budget for the Department of Defense. During this time Congress is able to exert control over the priorities, guiding principles, and issues that will be addressed by the department in the coming year. The 2018 incarnation of the NDAA, which has just been signed into law by the president, includes, nested in Title XVI, Subtitle C, provisions, a requirement that the White House and the DOD meaningfully investigate, consider, and establish national standards and guidance in the cybersecurity and cyber-warfare space. They must explore the development of a national posture for these issues.
