National Institute of Standards and Technology, (Final Draft) Systems Security Engineering Guideline: An Integrated Approach to Building Trustworthy Resilient Systems (NIST Special Publication 800-160) (Sept. 2016) (full-text).
Engineering-based approaches to solutions are essential to managing the growing complexity, dynamicity, and interconnectedness of today's systems — as exemplified by cyber-physical systems and systems-of-systems, including the Internet of Things. Managing the complexity of today's [[system]s and being able to claim that those systems are trustworthy and secure means that first and foremost, there must be a level of confidence in the feasibility and correctness-in-concept, philosophy, and design, regarding the ability of a system to function securely as intended. Failure to address the complexity issue in this manner will continue to leave the Nation susceptible to the consequences of an increasingly pervasive set of disruptions, hazards, and threats with potential for causing serious, severe, or even catastrophic consequences. This publication attempts to bring greater clarity to the difficult and challenging problems associated with a systems-oriented viewpoint on realizing trustworthy secure systems — and does so through the considerations set forth in a set of standards-based systems engineering processes applied throughout the system life cycle.
The final public draft of this publication represents a targeted update to the second public draft published in May 2016. As part of this update, some important long-term design decisions were taken that are reflected in the final draft. To ensure that the publication provides the utmost clarity and focus for our customers, several of the supporting appendices in the second public draft are being recast into their own publication. Special Publication 800-160 will become the flagship publication for the NIST Systems Security Engineering Initiative. The following supporting NIST publications will be developed and published in 2017 and beyond:
- Special Publication 800-160A, Systems Security Engineering: Considerations for System Resilience in the Engineering of Trustworthy Secure Systems;
- Special Publication 800-160B, Systems Security Engineering: Considerations for Software Assurance in the Engineering of Trustworthy Secure Systems; and
- Special Publication 800-160C, Systems Security Engineering: Considerations for Hardware Assurance in the Engineering of Trustworthy Secure Systems.
In addition to the scoping decisions described above, this update includes:
- The incorporation of changes based on the comments received from the sixty-day public review;
- The inclusion of additional International Standards in the references and related publications section; and
- The inclusion of hyperlinks throughput the document to facilitate [[customer] ease of use and more efficient access to key content.
