As we push computers to "the edge" building an increasingly complex world of interconnected information systems and devices, security and privacy continue to dominate the national dialog. There is an urgent need to further strengthen the underlying systems, component products, and services that we depend on in every sector of the critical infrastructure—ensuring those systems, components, and services are sufficiently trustworthy and provide the necessary resilience to support the economic and national security interests of the United States.
 
This update to NIST Special Publication 800-53 (Revision 5) responds to the need by embarking on a proactive and systemic approach to develop and make available to a broad base of public and private sector organizations, a comprehensive set of safeguarding measures for all types of computing platforms, including general purpose computing systems, cyber-physical systems, cloud and mobile systems, industrial/process control systems, and Internet of Things (IoT) devices. Those safeguarding measures include security and privacy controls to protect the critical and essential operations and assets of organizations and the personal privacy of individuals. The ultimate objective is to make the information systems we depend on more penetration resistant to attacks; limit the damage from attacks when they occur; and make the systems resilient and survivable.
 
Revision 5 of this foundational NIST publication represents a one-year effort to develop the next generation security and privacy controls that will be needed to accomplish the above objectives. It includes changes to make the controls more consumable by diverse groups including, for example, enterprises conducting mission and business operations; engineering organizations developing systems and systems-of-systems; and industry partners building system components, products, and services. The major changes to the publication include:

• Making the security and privacy controls more outcome-based by changing the structure of the controls;
• Fully integrating the privacy controls into the security control catalog creating a consolidated and unified set of controls for information systems and organizations, while providing summary and mapping tables for privacy-related controls;
• Separating the control selection process from the actual controls, thus allowing the controls to be used by different communities of interest including systems engineers, software developers, enterprise architects; and mission/business owners;
• Promoting integration with different risk management and cybersecurity approaches and lexicons, including the Cybersecurity Framework;
• Clarifying the relationship between security and privacy to improve the selection of controls necessary to address the full scope of security and privacy risks; and
• Incorporating new, state-of-the-practice controls based on threat intelligence and empirical attack data, including controls to strengthen cybersecurity and privacy governance and accountability.

Your feedback on this draft publication is important to us. We appreciate each contribution from our reviewers. The very insightful comments from the public and private sectors, nationally and internationally, continue to help shape the final publication to ensure that it meets the needs and expectations of our customers.
