The document discusses the relationship between cybersecurity and safety in the context of ultra-large-scale systems and the Internet of Things (IoT). It highlights key cybersecurity challenges such as prevention, detection, and mitigation while emphasizing the need for multidisciplinary strategies to effectively address these issues. Additionally, it explores the complexities of interconnected systems and the importance of collaboration across various fields.

• Key elements:
– Computing devices
– Business and organizational policies
– Environment (including people)
• Forces:
– Competition for resources
– Unexpected environmental changes
– Decentralized control
– Demand for assurance (safety and
security)

Approach
• Key Cybersecurity Challenges:
– Prevention
– Detection
– Mitigation
• Competing Concerns:
• Safety
• Information Access (e.g., “Internet of Things”)
• Heterogeneity of Systems and Stakeholders
• Multi-Disciplinary Strategies:
– Leverage enabling technologies from other disciplines
(e.g., biology, AI, control, cognitive & social science, etc.)
– Collaborate with other disciplines for a more holistic,
systemic approach to address cybersecurity and safety.
