Classifying COVID-19 Disinformation on Twitter using a Convolutional Neural Network

Topics: Privacy, Security and Trust in Social Media; AI and Machine Learning for Security

Authors: Mohamad Nabeel and Christine Große

Affiliation: Department of Information Systems and Technology, Mid Sweden University, Holmgatan 10, Sundsvall, Sweden

Digital Object Identifier: 10.5220/0010774800003120

Proceedings of ICISSP 2022, ISBN: 978-989-758-553-1

Quick Abstract

Disinformation regarding COVID-19 is spreading rapidly on social media platforms and can cause undesirable consequences for people who rely on such content. To combat disinformation, several platform providers have implemented intelligent systems to detect disinformation and provide measurements that apprise users of the quality of information being disseminated on social media platforms. For this purpose, intelligent systems employing deep learning approaches are often applied, hence, their effectivity requires closer analysis. The study begins with a thorough literature review regarding the concept of disinformation and its classification. This paper models and evaluates a disinformation detector that uses a convolutional neural network to classify samples of social media content. The evaluation of the proposed deep learning model showed that it performed well overall in discriminating the fake-labelled tweets from the real-labelled tweets; the model yielded an accuracy score of 97.2%, a precision score of 95.7% and a recall score of 99.8%. Consequently, the paper contributes an effective disinformation detector, which can be used as a tool to combat the substantial volume of disinformation scattered throughout social media platforms. A more standardised feature extraction for disinformation cases should be the subject of subsequent research.

Topics: Legal and Regulatory Issues; Security Awareness and Education

Author: Christine Große

Digital Object Identifier: 10.5220/0010186803190330

Proceedings of ICISSP 2021, ISBN: 978-989-758-491-6

Quick Abstract

This paper develops an analytical framework to assess information in planning for critical infrastructure protection (CIP). Critical infrastructure concerns various societal functions that ensure the daily life, endurance and progress of societies. Thus, CIP involves a considerable number of actors in a multi-level planning that relies on inter-organisational information sharing. Based on a Swedish case of CIP, this study aims to foster information assessment and management that bridge the inherent conflicts between information sharing and information security in CIP. Analyses of the information alongside the Swedish STYREL process first exemplify crucial deficiencies in the inter-organisational, national emergency response planning and then specify a set of dimensions and attributes as baseline for assessing information and information processing in CIP. Four stages in the Swedish approach cause a filtering and altering of information that affect the quality of decisions alongside the process and the emergency response plan that relies on them. By assessing the information basis in this large-scale approach, the paper contributes evidence-based foundations for information management in inter-organisational settings, such as the multi-level planning for CIP.

Choice of Airport in Extinguishing Wildfires: Model and Cases

Topics: Optimization; OR in Transportation; OR in Emergency Management

Authors: Louise Ekström and Christine Große

Affiliation: Department of Information Systems and Technology, Mid Sweden University, Holmgatan 10, Sundsvall, Sweden

Digital Object Identifier: 10.5220/0009166703640371

Proceedings of ICORES 2020, ISBN: 978-989-758-396-4

Quick Abstract

This paper develops a model to support the optimal choice of an airport as a base for the flying vehicles that are operated to extinguish wildfires and forest fires. Based on experiences from the two largest wildfires in Swedish history, this study models the optimisation as a balanced transportation problem. In both cases, the model selected the airport that is closest to the fire area. If the capacity of the chosen airport was insufficient to host all of the flying vehicles, then the model added a second airport which is also nearby the wildfire area. The cases demonstrate that the total cost of the operation is lower when the extinguishing work is concentrated in an area that has a short distance between the airport and the fire, the fuel depots and the pilots’ accommodation. Improved access to relevant data in the context of crisis management by air could allow for the inclusion of additional parameters and correct data in the optimisation model, which could in turn provide more comprehensive decision-making support.

Integration of Data Envelopment Analysis in Business Process Models: A Novel Approach to Measure Information Security

Topics: Risk and Reputation Management; Security Awareness and Education

Authors: Agnes Åkerlund and Christine Große

Affiliation: Department of Information Systems and Technology, Mid Sweden University, Holmgatan 10, Sundsvall, Sweden

Digital Object Identifier: 10.5220/0008875802810288

Proceedings of ICISSP 2020, ISBN: 978-989-758-399-5

Quick Abstract

This article explores the question of how to measure information security. Organisational information security is difficult to evaluate in this complex area because it includes numerous factors. The human factor has been acknowledged as one of the most challenging factors to consider in the field of information security. This study models the application of data envelopment analysis to business processes in order to facilitate the evaluation of information security that includes human factors. In addition to the model, this study demonstrates that data envelopment analysis provides an efficiency measure to assess the information security level of a business process. The novel approach that is proposed in this paper is exemplified with the aid of three fictive processes. The Business Process Model and Notation has been used to map the processes because it facilitates the visualisation of human interactions in processes and the form of the processed information. The combination of data envelopment analysis with process modelling and analyses of process deficiencies and threats to information security enables the evaluation of information security to include human factors in the analyses. Moreover, it provides a measure to benchmark information security in organisational processes.

Are You Ready When It Counts? IT Consulting Firm’s Information Security Incident Management

Proceedings of ICISSP 2019, ISBN: 978-989-758-359-9

Quick Abstract

Information security incidents are increasing both in number and in scope. In consequence, the General Data Protection Regulation and the Directive on security of network and information systems force organisations to report such incidents to a supervision authority. Due to the growing of both the importance of managing incidents and the tendency to outsourcing, this study focuses on IT-consulting firms and highlights their vulnerable position as subcontractors. This study thereby addresses the lack of empirical research on incident management and contributes valuable insights in IT-consulting firms’ experiences with information security incident management. Evidence from interviews and a survey with experts at IT-consulting firms focuses on challenges in managing information security incidents. The analyses identify and clarify both new and known challenges, such as how the recent regulations affect the role of an IT-consulting firm and how the absence of major incidents influences stakeholder awareness. Improvements of IT-consulting firm’s incident management process need to address internal and external communication, the information security awareness of employees and customers and the adequacy of the cost focus.

Quick Abstract

3D-printing, or as it is also known, additive manufacturing (AM), is promising to be one of the determining manufacturing technologies of the present century. It is not a single technology but a family of rather different ones common in the way components are made, adding materials layer by layer. Additive manufacturing is already quite competitive to existing and well established technologies, but it also can provide unprecedented flexibility and complexity of shapes making components from the materials as different as cheese, chocolate and cream, live cells, concrete, polymers and metal. Many more materials we were not even thinking about few years ago are also becoming available in additive manufacturing, making it really believable that “only the sky is the limit”. During the time available for the keynote lecture, we will analyze the present position of AM in relation to other technologies, the features that make it so promising and its influence upon the part of our life we call sports and health, using the examples relevant to the Congress areas from computer systems to sports performance. Out of all enormities of materials available for different representatives of this manufacturing family we will concentrate at polymers and metals. AM technologies working with these two material families are already providing some unique solutions within the application areas relevant to the Congress' scope. We will also talk about some limitations inherent to the AM in polymers and metals to have the awareness that though the limit is somewhere “high in the sky”, it still exists.

Quick Abstract

Sensor nodes containing pairs of temperature and humidity sensors were assessed as a mean of garment performance and comfort studies. Modern sensors are small, low weight and produce minimal disturbance when placed under the garments and in the footwear. Four sensor nodes were used to provide dynamic information about heat and humidity transfer properties of garments during the tests in realistic conditions. Pilot studies were carried out for the few models of cross country skiing garments and waders. Main studies were carried out in the wind tunnel at Mid Sweden University having pivoted treadmill, temperature control and rain capacity. Additional experiments with the waders were carried out in a large water tank. Studies of the temperature and humidity dynamics under the garments containing microporous membranes illustrate the importance of recognizing main features of such materials. In particular, such membranes can only transport moisture from the side where humidity is higher. It means that garments and footwear containing such membranes will potentially behave differently when ambient air humidity changes. In particular, modern garments with incorporated microporous membranes being superior at low ambient air humidity can be dramatically less effective for moisture transfer from the body in the rain.

SEC-SNMP: POLICY-BASED SECURITY MANAGEMENT FOR SENSOR NETWORKS

Topic: Sensor and Mobile Ad Hoc Network Security

Authors: Qinghua Wang and Tingting Zhang

Affiliation: Mid Sweden University, Sweden

Digital Object Identifier: 10.5220/0001928602220226

Proceedings of SECRYPT 2008/ICETE, ISBN: 978-989-8111-59-3

Quick Abstract

In this paper, we present a sensor network security management framework called Sec-SNMP, which organizes and manages security related behaviors in sensor networks based on security policies. There are three main components in Sec-SNMP: Sec-SNMP manager, Sec-SNMP agent and a policy control and deployment protocol. Sec-SNMP manager provides the interface between human administrator and the managed mesh network. Sec-SNMP agent represents Sec-SNMP manager to enforce security policies within the managed mesh network. The policy control and deployment protocol allows the communication between Sec-SNMP manager and Sec-SNMP agents. The security management for sensor networks is still in its germinal stage, and this paper provides a good guideline for future research.
