This paper investigates the vulnerability of smart power grids to load redistribution (LR) attacks in the presence of insider threats. We introduce a stochastic optimization model to minimize the expected risk of high operation costs due to LR attacks by protecting critical grid components and deploying detection technologies, such as honeypots, to detect insider threats and prevent information leakage. Our model accounts for uncertainties in insider presence, honeypot effectiveness, and attack targets, and uses the conditional value-at-risk (CVaR) measure, which can be adjusted based on the decision-maker's conservatism. In addition, it accounts for real-time power demand variations and dynamic false-data injection by attackers. To enhance tractability, we transform our model, originally formulated as a trilevel mixed-integer nonlinear programming (Tri-MINLP) problem, into an approximate single-level mixed-integer linear programming (MILP) formulation. We apply our proposed model to the IEEE 14-bus test system, and our results highlight the effectiveness of our approach in lowering the risk of high operation costs due to LR attacks. In addition, we present several insights by assessing the impact of key factors on the expected financial risk of attacks, including the protection budget, insider-threat likelihood, honeypot-detection effectiveness, and the defender's decision-making conservatism.</p>","PeriodicalId":21472,"journal":{"name":"Risk Analysis","volume":"46 9","pages":"e70336"},"PeriodicalIF":4.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13525720/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes an integrated methodology to assess transboundary hazards and population vulnerability across European cross-border regions. The framework combines georeferenced data on extreme weather events, wildfires, industrial areas, and nuclear power plants with a population-based vulnerability analysis. The results revealed pronounced spatial heterogeneity in transboundary hazards distribution across Europe. Extreme weather events affected most European border regions, with the highest values observed in central Europe and along the Portugal-Spain border. Wildfire hazards were strongly concentrated in southern and Mediterranean regions, particularly in the Iberian Peninsula and the Balkans. Technological hazards displayed a more localized pattern, with nuclear power plant-related hazards mainly concentrated in central European border regions and industrial hazards clustered in highly industrialized areas, notably in Belgium, the Netherlands, Germany, Italy, and Switzerland. The combined hazard analysis showed that the highest transboundary hazard levels occurred in regions where multiple hazards spatially co-occurred, such as the Italy-Switzerland, Belgium-the Netherlands, and Portugal-Spain borders, highlighting the importance of multi-hazard interactions. The assessment found that vulnerability was largely determined by population density and demographic structure, with the highest levels occurring in densely populated areas along the Belgium-Germany border.

A frequent approach is the use of input-output macroeconomic modeling, yet there is a lack of clarity about how ex ante parameterization and other methodological decisions affect output estimates, warranting further investigation. In this paper, we quantify the macroeconomic effects of three significant natural hazard US power outages: Hurricane Ian (2022), the 2021 Texas Blackouts, and Tropical Storm Isaias (2020). Our analysis evaluates the sensitivity of three commonly used data parameterization techniques (household interruptions, kWh lost, and satellite luminosity), along with three static models (Leontief and Ghosh, critical input, and inoperability input-output). We find the mean domestic loss estimates for these three blackout events to be $2.42 Bn, $3.24 Bn, and $2.27 Bn, respectively. However, data parameterization techniques can alter estimated losses by up to 52.8% of the mean. Consistent with the wide range of outputs, we find that risk analysis stemming from gross output estimate severity is highly sensitive to model architecture, data parameterization, and analyst assumptions. Results sensitivity is not uniform across models and arises from important a priori analyst decisions, demonstrated by data parameterization techniques yielding up to 55.9% differences from empircal results within a model.

Despite widespread scientific recognition of deep uncertainty (large ranges of possibility) in climate conditions, this nuance is often lost in translation to policy and planning contexts; instead, conditions are presented as single projections. This means that communities are making large-scale infrastructure investments and long-term policy commitments based on false precision, leaving them unprepared for climate surprises or potentially wasting resources and disrupting communities unnecessarily by overadapting. To examine how climate uncertainties are represented and accounted for in adaptation planning, we conducted a structured review of 39 climate risk and vulnerability assessments from across the world, using sea level rise as a case study. These documents inform policy that guides billions of dollars in infrastructure investments and shape community preparedness strategies. Our analysis reveals that only 54% of these documents correctly represent sea level rise as deeply uncertain. This issue is compounded when making decisions; 71% of decisions were made by misapplying scenarios as individual projections to plan for, rather than as a tool for exploring potential future conditions, directly contradicting their intended use. This demonstrates a gap between scientific understanding of climate uncertainty and planning practice. Addressing this gap requires improved uncertainty communication, moving beyond just quantifying uncertainty to also characterizing uncertainty. This must be done in conjunction with the support of decision makers to incorporate a stronger understanding of uncertainty into planning by using tools designed specifically for decision making in deeply uncertain environments.</p>","PeriodicalId":21472,"journal":{"name":"Risk Analysis","volume":"46 9","pages":"e70331"},"PeriodicalIF":4.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13538798/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148881554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three classification models are studied: a complete tree, a sparse (specifically, fast-and-frugal) tree, and a risk table. To focus on transparency, all three models make identical classifications and thus have equal accuracy. We assess and score three aspects of transparency for each model: time required to learn to a strict criterion, accuracy of application under time pressure, and accuracy in a delayed surprise memory recall test. In a between-participants design, the fast-and-frugal tree is learned more quickly, applied more accurately, and recalled more accurately than the complete tree and the risk table; all statistical effect sizes are large. The recall accuracy of the fast-and-frugal tree is, in contrast to the other two models, robust to individual differences in statistical numeracy and risk literacy.
