Executive Order 13636 (EO 13636), Improving Critical Infrastructure Cybersecurity (February 2013), directs the National Institute of Standards and Technology (NIST) to develop a framework to reduce cyber risks to critical infrastructure that consists of a voluntary set of standards, methodologies, procedures, and processes to address cyber risks. After the 2014 release of the NIST Cybersecurity Framework, DOE collaborated with energy sector owners and operators to develop the Energy Sector Cybersecurity Implementation Guidance, designed to help the energy sector establish or align existing cybersecurity risk management programs to meet the objectives of the NIST Cybersecurity Framework. Section 9 of the executive order also directs SSAs to designate critical infrastructure at greatest risk within each sector. DOE meets regularly with designated energy entities to align and prioritize federal cybersecurity capabilities and roles.
