• 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.
