Announcement

This final public draft offers significant content and design changes that include a renewed emphasis on the importance of systems engineering and viewing systems security engineering as a critical subdiscipline necessary to achieving trustworthy secure systems. This perspective treats security as an emergent property of a system. It requires a disciplined, rigorous engineering process to deliver the security capabilities necessary to protect stakeholders’ assets from loss while achieving mission and business success.

Bringing security out of its traditional stovepipe and viewing it as an emergent system property helps to ensure that only authorized system behaviors and outcomes occur, much like the engineering processes that address safety, reliability, availability, and maintainability in building spacecraft, airplanes, and bridges. Treating security as a subdiscipline of systems engineering also facilitates making comprehensive trade space decisions as stakeholders continually address cost, schedule, and performance issues, as well as the uncertainties associated with system development efforts.

In particular, this final public draft:

  • Provides a renewed focus on the design principles and concepts for engineering trustworthy secure systems, distributing the content across several redesigned initial chapters
  • Relocates the detailed system life cycle processes and security considerations to separate appendices for ease of use
  • Streamlines the design principles for trustworthy secure systems by eliminating two previous design principle categories
  • Includes a new introduction to the system life cycle processes and describes key relationships among those processes
  • Clarifies key systems engineering and systems security engineering terminology
  • Simplifies the structure of the system life cycle processes, activities, tasks, and references
  • Provides additional references to international standards and technical guidance to better support the security aspects of the systems engineering process

NIST is interested in your feedback on the specific changes made to the publication during this update, including the organization and structure of the publication, the presentation of the material, its ease of use, and the applicability of the technical content to current or planned systems engineering initiatives.
