    Study Notes

    • Protecting physical facilities requires multiple layers of interdependent systems, including surveillance, intrusion detection, deterrents, guards, barriers, locks, and access control. Hardware devices may employ antitampering features to ensure content authenticity or protect sensitive information.
    • As our world becomes digital, both hardware and software systems are at risk for disruption or damage from digital threats. Integrating cybersecurity into systems engineering (SE) is essential through Systems Security Engineering (SSE) approaches.
    • Cybersecurity refers to the confidentiality, integrity, and availability of information assets. Trustworthiness is a broader concept including privacy, reliability, resilience, safety, and security.
    • SSE practitioners should possess skills in various areas, including security requirements, architecture views, threat assessment, networking, security technologies, hardware and software security, testing, and supply chain risk assessment.
    • NIST 800-160 Vol. 1 and Vol. 2 emphasize the importance of integrating cybersecurity into SE processes and use the same terminology as the ISO/IEC/IEEE 15288 standard for a common understanding between SE and SSE practitioners.
    • Loss-Driven Systems Engineering (LDSE) unifies quality characteristics that address potential losses associated with developing and using systems. LDSE focuses on the potential losses, rather than just the desired capabilities.
    • Collaborative efforts should be made among SE practitioners to address the adversities, weaknesses, defects, flaws, exposures, hazards, and vulnerabilities considered, the assets and losses considered, and the coping mechanisms considered.
    • Loss-driven requirements should be integrated into the overall stakeholder and system requirements development. Architectural and design decisions should be made holistically, and risks associated with all loss-driven areas should be integrated into the project's risk management activities.
    • The SE Handbook and NIST 800-160 provide examples of how the SE and SSE processes can be broken down and integrated for a better understanding of their relationships.
    • The Stuxnet attack on a cyber-physical system serves as an example of the importance of system security.
    • Loss-driven QCs, such as resilience, safety, security, sustainability/disposability, and availability, have significant commonality and synergy that should be leveraged.
