A better world through a systems approach

Systems Security Engineering

Mission & Objectives

This working group’s mission is to provide Systems Engineers and Systems Engineering with effective means and methods for sustainable system functionality under advanced adversarial attack.

This working group believes that system engineering cannot succeed without accepting core responsibility for enabling and facilitating effective system security – partly in system requirements, partly in system trade space recognition, but mainly in system thinking applied to concepts of operations and systems architecture. Sustaining system functionality in the face of intelligent determined attack requires self preservation capabilities that adapt and evolve with equal intelligence, determination, and strength of community. This requires full system awareness and adaptability, and system-of-system relationships. Security engineering alone cannot accomplish this.

It is fitting for INCOSE to tackle Next Generation Security, as the issues are leading edge systems engineering issues: architecture, systems of systems, self organizing systems, security tradeoffs with human factors, systems thinking  – things that are typically high level integrated-system SE issues.

Current system security strategies are inadequate and cannot be fixed by security engineers alone. The reason is evident: attack communities operate as intelligent, multi-agent, self organizing, system-of-systems – with swarm intelligence, tight learning loops, fast evolution, and dedicated intent. With few exceptions, the systems being targeted are alone, senseless and defenseless – relying on outside benevolence for protection, whether this be separate security systems, laws and penalties, or perceived probabilities of being an overlooked target.

This working group's objectives are to instill systems engineering responsibility for sustainable systems functionality in the face of intelligent, determined, and highly competent system adversaries; to facilitate the assimilation and dispatch of that responsibility; and to Instigate self-sustaining cross- community involvement between systems engineers, security engineers, and system security standards..

Participants in this working group’s projects are developing vanguard critical understandings.

Intended Outcomes

  • Fundamental responsibility within systems engineering accepted and integrated.
  • ConOps of actionable next-generation security structures and strategies profiled.
  • Next-generation-enabling security concepts established in the relevant standards bodies.
  • Identification and publication of a relevant body of knowledge appropriate for the Systems Engineering Body of Knowledge (SEBoK).
  • Development and maintenance of appropriate contributions to the INCOSE Systems Engineering Handbook .
  • Socialization of work efforts with papers for INCOSE’s journal of Systems Engineering, papers and tutorials at the International Symposium, INSIGHT theme issues, and educational and tutorial Webinars.
  • Working alliances with other organizations concerned with secure sustainable systems.

Planned Working Sessions at the Next Events

This working group holds workshops every year at the two main INCOSE events: the International Workshop (usually Jan/Feb) and the International Symposium (usually Jun/Jul). All working group members receive schedule and agenda announcements, and all INCOSE members can view the event planning details on the working group web-site. Non-INCOSE members with interest may inquire at the address shown in the Leadership box.
