Review of detection, assessment and mitigation of security risk in smart grid
2017
The integration of Information and Communication Technology (ICT) into the existing power grid has created new problems to the grid. The grid network has become more vulnerable to security threats and risk which is a corollary to the modern data network. Smart Grid has strict latency requirement for data communication and the violation of this latency is very costly. This paper assesses the threats and vulnerabilities associated with the Smart Grid network and reviews the methods to mitigate these security risks.
Pedagogical approaches for e-assessment with authentication and authorship verification in Higher Education
2019
Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey.…
Stakeholders, contradictions and salience: An empirical study of a Norwegian G2G effort
2006
Author's version of a chapter in Proceedings of the 39th Annual Hawaii International Conference on Systems Sciences. Also available from the publisher at http://dx.doi.org/10.1109/HICSS.2006.436 Previous studies indicate that the expected effects of e-Government are slower to realize than initially expected. Several authors argue that e-Government involves particularly complex settings, consisting of a variety of stakeholders promoting different and often conflicting objectives. Yet, few studies have explicitly addressed the inherent challenges of this complexity. This study focuses on the extent to which contradictory stakeholder objectives can help explain the relatively slow progress of …
Psychosocial Risks, Work Engagement, and Job Satisfaction of Nurses During COVID-19 Pandemic
2020
Context:COVID-19 pandemic is a serious health emergency that has affected countries all over the world. Health emergencies are a critical psychosocial risk factor for nurses. In general, psychosocial risks constitute serious problems as they impact workers' health, productivity, and efficiency. Despite their importance, few studies analyze nurses' psychosocial risks during a health emergency caused by a pandemic or analyze their perception of the emergency and its relation to such risks.Objectives:To analyze the perception of COVID-19 by nurses, especially about measures, resources, and impact on their daily work. Also, to analyze these professionals' psychosocial risks and the relationship…
A Knowledge Interface System for Information and Cyber Security Using Semantic Wiki
2018
Resilience against information and cyber security threats has become an essential ability for organizations to maintain business continuity. As bulletproof security is an unattainable goal, organizations need to concentrate to select optimal countermeasures against information and cyber security threats. Implementation of cyber risk management actions require special knowledge and resources, which especially small and medium-size enterprises often lack. Information and cyber security risk management establish knowledge intensive business processes, which can be assisted with a proper knowledge management system. This paper analyzes how Semantic MediaWiki could be used as a platform to assis…
Watermarking for ontologies
2011
In this paper, we study watermarking methods to prove the ownership of an ontology. Different from existing approaches, we propose to watermark not by altering existing statements, but by removing them. Thereby, our approach does not introduce false statements into the ontology. We show how ownership of ontologies can be established with provably tight probability bounds, even if only parts of the ontology are being re-used. We finally demonstrate the viability of our approach on real-world ontologies.
Developing Cybersecurity in an Industrial Environment by Using a Testbed Environment
2023
Critical infrastructure protection requires a testing environment that allows the testing of different kinds of equipment, software, networks, and tools to develop vital functions of the critical industrial environment. Used electrical equipment must be reliable, capable and maintain a stable critical industrial ecosystem. An industrial business needs to develop cybersecurity capabilities that detect and prevent IT/ICT and OT/ICS threats in an industrial environment. The emerging trend has been to create security operations center (SOC) services to detect ICS-related threats in enterprise networks. The energy supply sector must consist of crucial elements for safe business continuity and su…
La rétention de sûreté : la première mesure de sûreté privative de liberté depuis le nouveau Code pénal
2015
The French criminal law is characterised by a willingness to prevent recidivism. To give concrete expression to this will, security measures are implemented among which the secure detention. However, the secure detention is not an ordinary measure and gives rises to many debates which, in fact, take up old and recurrent controversies. This measure is based on the assumption that sexual and/or violent criminals show a disease which may suggest a risk of a second offence. As a result, by considering them as sick persons, the legislator asserts that they can be treated. Accordingly, medical care is advised as the only solution to prevent a second offence. However, this disease itself often ind…
A privacy enhanced device access protocol for an IoT context
2013
In this paper, we present the case for a device authentication protocol that authenticates a device/service class rather than an individual device. The devices in question are providing services available to the public. The proposed protocol is an online protocol, and it uses a pseudo-random temporary identity scheme to provide user privacy. This allows the Internet-of-Things device to have full assurance of the user, with respect to the request service, while permitting the user to remain anonymous with respect to the device. The user can then enjoy identity and location privacy in addition to untraceability with respect to device access. Copyright © 2013 John Wiley & Sons, Ltd.
Access Security and Personal Privacy in Public Cellular Communication Systems: The Past, the Present and Beyond 2020
2010
In order to predict the future one needs to understand the past and then interpolate as best as possible. We expect this to work reasonably well for a “2020 Scenario”, but we do not expect this approach to be valid for a “Beyond 2020” scenario.
