The EU prioritizes cybersecurity and data protection due to rising cyber threats and digital transformation. It employs regulations like GDPR for personal data and the NIS Directive for critical infrastructure resilience. This study analyzes their impact, challenges, and interplay, also comparing them globally to assess effectiveness in safeguarding digital security and fostering trust.

This study analyzes resource provisioning with strict reliability demands. It characterizes optimal cost scaling in chance-constrained problems as reliability increases. It reveals limitations of common distributionally robust optimization methods, proposes improvements using marginal distributions or f-divergences, and offers a line search for near-optimal solutions, overcoming data sample limitations.

AI could revolutionize UK sectors, enhancing productivity and decision-making, notably in finance by automating processes and refining decisions like underwriting. However, its rapid evolution raises uncertainties and financial stability risks, including systemic issues from flawed AI models, market instability, and cyber threats. The Financial Policy Committee (FPC) is assessing these risks to ensure safe AI adoption, supporting sustainable growth through vigilant monitoring and regulation.

The ESAs Spring 2025 update highlights geopolitical tensions and cyber risks as major threats to EU financial stability. Trade disputes, policy shifts, conflicts, and economic fragmentation demand increased vigilance. Financial institutions face uncertainties in international markets, liquidity, and AI's role. Proactive risk management, cyber resilience, and monitoring global linkages are crucial.

Cyberattacks primarily impact firm value through increased costs rather than sales declines, indicating financial burdens over reputational damage. Costs persist beyond the short term, and firms invest in recovery efforts. Over time, reputational concerns have diminished as cyber resilience improves. These findings emphasize the need for strong corporate risk management, focusing on cost recovery, recovery planning, and trust restoration strategies tailored to specific contexts.

En 2024, la France vit plus que jamais dans une « société du risque» face aux tensions géopolitiques, au décrochage économique européen et à l'aggravation des risques climatiques (année la plus chaude, événements naturels coûteux). Les Français se sentent vulnérables et inquiets face aux risques de guerre et à la capacité future d'assurer les risques climatiques et autres. Le secteur de l'assurance, bien que créateur d'emplois et gérant un grand nombre de sinistres (dont le coût des événements naturels a atteint 5 milliards d'euros en France), fait face à une hausse de la sinistralité (dégâts des eaux, sinistres graves pour les professionnels, cyberattaques, sinistralité agricole record) et des coûts (réparation automobile, dépenses de santé).

This study analyzes ransomware negotiations through a social psychological lens, identifying three phases and distinct negotiation strategies. It offers practical insights for organizations to enhance resilience by understanding threat actor tactics and tailoring response protocols for effective negotiation.

A structured IT outsourcing risk management policy is crucial for navigating third-party service complexities. This study proposes a framework integrating IT outsourcing principles with COBIT standards, covering risk identification, analysis, mitigation, and ongoing monitoring. Implementing this policy enhances organizational asset protection, operational continuity, and minimizes outsourcing risks. It improves information security and business process efficiency. This framework provides practical guidance for organizations to effectively manage risks and optimize IT outsourcing value.

Increased cyber risk drives U.S. banks to diversify information sources, especially large, nationally chartered banks. This suggests cyber threats erode data confidence, forcing banks to seek verification. Specialized institutions are more vulnerable to data integrity disruptions.

This study integrates cybersecurity risks into a neoclassical growth model, revealing that proactive investments enhance long-term stability, while industry-specific vulnerabilities (capital-intensive resilience vs. labor-intensive disruptions) and systemic risks affect macroeconomic resilience. Optimal resource allocation, adaptive risk strategies via Bayesian updating, and prioritizing cybersecurity in long-term planning balance security with growth.
