Network safety is an academic concept and research field concerned with the analysis, design, and management of interconnected systems to prevent failures, mitigate risks, and ensure reliable operation under various conditions. It investigates the vulnerabilities, interdependencies, and potential for cascading effects within complex networks, such as those governing critical infrastructure like nuclear power grids or control systems. Key characteristics include systemic risk assessment, resilience planning, and the integration of physical and cyber security measures across multiple nodes or components. Its significance lies in maintaining overall system integrity, preventing widespread disruptions, and safeguarding public welfare against complex, systemic hazards.
