Our nation's critical infrastructure includes the public and private systems and assets vital to national security, economic stability, and public health and safety. Federal policy identifies 16 critical infrastructure sectors, including the financial services, energy, transportation, and communications sectors. To better address cyber-related risks to critical infrastructure, in 2014, NIST developed, as called for by federal law and policy, the Framework for Improving Critical Infrastructure Cybersecurity, a voluntary framework of cybersecurity standards and procedures for industry to adopt.
