Cyberattacks, Psychological Distress, and Military Escalation: An Internal Meta-Analysis

Journal of Global Security Studies, Год журнала: 2022, Номер 8(1)

Опубликована: Дек. 19, 2022

Abstract To what extent can cyberattacks wreak havoc and terrorize modern society? Until now, this question has revolved around the potential of cyber operations to cause physical destruction or other material harm. In paper, we propose a broader interpretation. We submit that assessing cyber-threats through prism obscured human dimension threat. Instead, calculating gravity by measuring psychological distress. This approach recognizes even seemingly inconsequential levy tremendous damage traumatizing civilians, undermining societal cohesion, exacerbating cycles violence. test whether significant individual harm, employ an internal meta-analysis looking at eighteen studies conducted in three countries over 6 years. Across these studies, exposed 6,020 respondents simulated conventional attacks. conclude high levels harm—equal caused political violence terrorism. finding overturns widely accepted view are mere irritant best threat information security worst. Through lens, findings suggest nonphysically destructive trigger consequences constitute legally defined armed attack permits using force self-defense. discussing how onset distress generates pressure support retaliation lead military escalation.

Introduction: Cyber-conflict – Moving from speculation to investigation

Journal of Peace Research, Год журнала: 2024, Номер 61(1), С. 3 - 9

Опубликована: Янв. 1, 2024

Investigating cyber conflict is enormously difficult. The domain complex, quality data are sparse, international affairs shrouded in secrecy, and despite its seeming ubiquity, power has only recently entered the battlefield. In face of these challenges, we must rise to meet challenges cybersecurity research by deploying creative methods that collect verifiable probatory data, which allow for predictive models behavior. Against this backdrop, our special issue offers a vision embraces culture rigorous inquiry based on theoretically robust, policy relevant investigation. We highlight two key features. First, at intersection political science incorporate human dimension conflict. A security approach places people as primary objects recognizes individual-level analyses can shed light macro-level trends. Second, adopt rigorous, empirical methods. embrace broad tent collection techniques – spanning qualitative quantitative, experimental, observational research.

Cyberattacks and public opinion – The effect of uncertainty in guiding preferences

Journal of Peace Research, Год журнала: 2024, Номер 61(1), С. 103 - 118

Опубликована: Янв. 1, 2024

When it comes to cybersecurity incidents – public opinion matters. But how do voters form opinions in the aftermath of cyberattacks that are shrouded ambiguity? How people account for uncertainty inherent cyberspace forge preferences following attacks? This article seeks answer these questions by introducing an threshold mechanism predicting level attributional certainty required support economic, diplomatic or military responses cyberattacks. Using a discrete-choice experimental design with 2025 US respondents, we find lower is associated less retaliation, yet this contingent on suspected identity attacker and partisan identity. Diplomatic allies possess reservoir good will amplifies effect uncertainty, while rivals often given benefit doubt. We demonstrate encourages use cognitive schemas overcome ambiguity, fall back upon pre-existing politically guided views about country behind attack. If ambiguity surrounding has typically been discussed as operational strategic concern, shifts focus attention human positions mass forgotten important party during cyber conflict.

GITM: A GINI Index-Based Trust Mechanism to Mitigate and Isolate Sybil Attack in RPL-Enabled Smart Grid Advanced Metering Infrastructures

IEEE Access, Год журнала: 2023, Номер 11, С. 62697 - 62720

Опубликована: Янв. 1, 2023

The smart grid relies on Advanced Metering Infrastructure (AMI) to function. Because of the significant packet loss and slow transmission rate wireless connection between meters in AMI, these infrastructures are considered Low-power Lossy Networks (LLNs). routing protocol an AMI network is crucial for ensuring availability timeliness data transfer. IPv6 Routing Protocol lossy networks (RPL) excellent option communication configuration. However, it highly at risk against many external internal attacks, its effectiveness may be severely diminished by Sybil assault. Different trust-based techniques have been suggested mitigate attacks. existing trust systems high energy consumption issues, which cause a reduction performance LLNs due complex calculations node level. Therefore, this paper presents novel fog-enabled GINI index-based mechanism (GITM) attacks using forwarding behavior legitimate member nodes. Regarding identifying isolating assaults, our approach outperforms state-of-the-art methods. GITM detects isolates more number malicious nodes compared other within similar time frame. By proposed framework, attack detection increases 4.48%, reduces 21%, isolation latency 26.30% (concerning time). Furthermore, end-to-end delay merely 0.30% case, control messages decreases 28%.

Abstract Proximity is a core feature of theories political violence, with the effects attacks rippling outward so that geographically proximate individuals experience more severe than those distant. However, this model proximity and exposure unlikely to recur for cyberattacks. The incorporeality cyber incidents absence physical epicenter constrain mechanism coupling distance harm. To empirically test relationship between cyberattacks, we conducted field study involving 707 German respondents following ransomware attack in Düsseldorf. We find classical “ripple effect” reversed, trust highest among people closer lowest postulate firsthand its effects, distant employ abstract conceptions consequences do not align actual events. Consequently, does confer security, it can even amplify adverse exposure. This finding highlights need governments actively work assuage public fears

An intrusion detection model based on Convolutional Kolmogorov-Arnold Networks

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 14, 2025

The application of artificial neural networks (ANNs) can be found in numerous fields, including image and speech recognition, natural language processing, autonomous vehicles. As well, intrusion detection, the subject this paper, relies heavily on it. Different detection models have been constructed using ANNs. While ANNs are relatively mature to construct models, some challenges remain. Among most notorious these bloated caused by large number parameters, non-interpretability models. Our paper presents Convolutional Kolmogorov-Arnold Networks (CKANs), which designed overcome difficulties provide an interpretable accurate model. (KANs) developed from representation theorem. Meanwhile, CKAN incorporates a convolutional computational mechanism based KAN. model proposed is incorporating attention mechanisms into CKAN's logic. datasets CICIoT2023 CICIoMT2024 were used for training validation. From results evaluating performance indicators experiments, CKANs has attractive prospect. compared with other methods, predict much higher level accuracy significantly fewer parameters. However, it not superior terms memory usage, execution speed energy consumption.
