| 2025 | Balancing Generative AI and Critical Thinking to Develop Written Communication Skills in CybersecurityabstractAs cybersecurity education continues to evolve, the need for curricula that effectively balance the capabilities of generative Artificial Intelligence (AI) tools with the development of critical thinking and active learning skills has become increasingly urgent. This study addresses this challenge by proposing a curriculum for postgraduate cybersecurity education that focuses on developing transferable skills, particularly critical thinking and written communication. These skills are essential for cybersecurity professionals to excel in both their technical and communicationoriented responsibilities, meeting the growing demand of the cybersecurity industry in the age of AI. The proposed curriculum emphasizes the integration of constructivist learning principles and Bloom's taxonomy, two widely applied pedagogical models, to enhance learners' critical thinking and written communication skills. Designed for a penetration testing module, the curriculum follows a structured, step-by-step approach to build the necessary competences and empower aspiring cybersecurity professionals to meet the expectations of the cybersecurity industry. Through targeted activities, learners develop foundational knowledge while refining advanced written communication skills, equipping them to produce professional-level documentation, such as penetration testing reports. Generative AI is incorporated in the curriculum, providing opportunities for learners to experiment with AIgenerated content while fostering the cognitive skills needed to critically assess its accuracy, relevance, and alignment with professional standards. This study contributes to cybersecurity education by presenting a replicable curriculum model that equips learners with vital skills, preparing them to navigate the complexities of written communication responsibilities in cybersecurity roles and adapt to the evolving demands of the AI era.

| 2025 | A taxonomy of factors that contribute to organizational Cybersecurity Awareness (CSA)abstractPurpose Developing cybersecurity awareness (CSA) is becoming a more and more important goal for modern organizations. CSA is a complex sociotechnical system where social, technical and organizational aspects affect each other in an intertwined way. With the goal of providing a holistic representation of CSA, this paper aims to develop a taxonomy of factors that contribute to organizational CSA. Design/methodology/approach The research used a design science approach including a literature review and practitioner interviews. A taxonomy was drafted based on 71 previous research publications. It was then updated and refined in two iterations of interviews with domain experts. Findings The result of this research is a taxonomy which outline six domains for importance for organization CSA. Each domain includes several activities which can be undertaken to increase CSA within an organization. As such, it provides a holistic overview of the CSA field. Practical implications Organizations can adopt the taxonomy to create a roadmap for internal CSA practices. For example, an organization could assess how well it performs in the six main themes and use the subthemes as inspiration when deciding on CSA activities. Originality/value The output of this research provides an overview of CSA based on information extracted from existing literature and then reviewed by practitioners. It also outlines how different aspects of CSA are interdependent on each other. Joakim Kävrestad, Felicia Burvall, Marcus Nohlberg |

| 2024 | Design principles for cognitively accessible cybersecurity trainingabstractExploiting human behavior to gain unauthorized access to computer systems has become common practice for modern cybercriminals. Users are expected to adopt secure behavior to avoid those attackers. This secure behavior requires cognitive processing and is often seen as a nuisance which could explain why attacks exploiting user behavior continues to be a fruitful approach for attackers. While adopting secure behavior can be difficult for any user, it can be even more difficult for users with cognitive disabilities. This research focuses on users with cognitive disabilities with the intent of developing design principles for the development of cognitively accessible cybersecurity training. The target group is estimated to include almost 10% of all users but is previously understudied. The results show that the target group experience cybersecurity as cognitively demanding, sometimes to a degree that becomes incapacitating. Participating in cybersecurity training requires cognitive energy which is a finite resource. Cognitively accessible cybersecurity training requires a minimalist design approach and inclusion of accessibility functions. A minimalist design approach, in this case, means that both informative and design elements should be kept to a minimum. The rationale is that all such elements require cognitive processing which should be kept to a minimum. Joakim Kävrestad, Jana Rambusch, Marcus Nohlberg |

| 2023 | How privacy concerns impact Swedish citizens' willingness to report crimes: a quantitative mobile phone surveyabstractPurpose The purpose of this paper is to identify whether there is a lower willingness to report a crime if a victim must hand in their mobile phone as evidence. If that is the case, the research seeks to examine whether privacy concerns and lower willingness correlate with one another and thereby investigate whether privacy concerns could lead to fewer crimes being reported and resolved. Design/methodology/approach A mobile phone survey was distributed to 400 Swedish adults to identify their hypothetical willingness to report certain crimes with and without handing in their mobile phones as evidence. The results were then analysed using inferential statistics. Findings The result suggests that there is no meaningful correlation between privacy attitudes and willingness to report crime when the handover of a mobile phone is necessary. The results of this study however show a significant lower willingness to report crimes when the mobile phone must be handed in. Research limitations/implications Because the chosen target group were Swedish adults, the research results may lack generalisability for other demographics. Therefore, researchers are encouraged to test other demographics. Originality/value This paper’s contribution is the novel exploration of attitudes and behaviours regarding the combination of privacy, digital forensics, mobile phones and crime reportage. This research effort examined the problematic situation that can arise for victims of crime, the invasion of privacy when providing evidence by handing in a mobile phone to the police’s forensic unit for examination.

| 2021 | Exploring the meaning of usable security - a literature reviewabstractPurpose For decades, literature has reported on the perceived conflict between usability and security. This mutual trade-off needs to be considered and addressed whenever security products are developed. Achieving well-balanced levels of both is a precondition for sufficient security as users tend to reject unusable solutions. To assess it correctly, usability should be evaluated in the context of security. This paper aims to identify and describe universally applicable and solution-independent factors that affect the perceived usability of security mechanisms. Design/methodology/approach The selected methodology was a systematic literature review during which multiple database resources were queried. Application of predefined selection criteria led to the creation of a bibliography before backward snowballing was applied to minimize the risk of missing material of importance. All 70 included publications were then analyzed through thematic analysis. Findings The study resulted in the identification of 14 themes and 30 associated subthemes representing aspects with reported influence on perceived usability in the context of security. While some of them were only mentioned sparsely, the most prominent and thus presumably most significant ones were: simplicity, information and support, task completion time, error rates and error management. Originality/value The identified novel themes can increase knowledge about factors that influence usability. This can be useful for different groups: end users may be empowered to choose appropriate solutions more consciously, developers may be able to avoid common usability pitfalls when designing new products and system administrators may benefit from a better understanding of how to configure solutions and how to educate users efficiently.

| 2020 | Constructing secure and memorable passwordsabstractPurpose Using authentication to secure data and accounts has grown to be a natural part of computing. Even if several authentication methods are in existence, using passwords remain the most common type of authentication. As long and complex passwords are encouraged by research studies and practitioners alike, computer users design passwords using strategies that enable them to remember their passwords. This paper aims to find strategies that allow for the generation of passwords that are both memorable and computationally secure. Design/methodology/approach The study began with a literature review that was used to identify cognitive password creation strategies that facilitate the creation of passwords that are easy to remember. Using an action-based approach, attack models were created for the resulting creation strategies. The attack models were then used to calculate the entropy for passwords created with different strategies and related to a theoretical cracking time. Findings The result of this study suggests that using phrases with four or more words as passwords will generate passwords that are easy to remember and hard to attack. Originality/value This paper considers passwords from a socio-technical approach and provides insight into how passwords that are easy to remember and hard to crack can be generated. The results can be directly used to create password guidelines and training material that enables users to create usable and secure passwords.

| 2020 | Analyzing the usage of character groups and keyboard patterns in password creationabstractPurpose Using passwords to keep account and data safe is very common in modern computing. The purpose of this paper is to look into methods for cracking passwords as a means of increasing security, a practice commonly used in penetration testing. Further, in the discipline of digital forensics, password cracking is often an essential part of a computer examination as data has to be decrypted to be analyzed. This paper seeks to look into how users that actively encrypt data construct their passwords to benefit the forensics community. Design/methodology/approach The study began with an automated analysis of over one billion passwords in 22 different password databases that leaked to the internet. The study validated the result with an experiment were passwords created on a local website was analyzed during account creation. Further a survey was used to gather data that was used to identify differences in password behavior between user that actively encrypt their data and other users. Findings The result of this study suggests that American lowercase letters and numbers are present in almost every password and that users seem to avoid using special characters if they can. Further, the study suggests that users that actively encrypt their data are more prone to use keyboard patterns as passwords than other users. Originality/value This paper contributes to the existing body of knowledge around password behavior and suggests that password-guessing attacks should focus on American letters and numbers. Further, the paper suggests that forensics experts should consider testing patterns-based passwords when performing password-guessing attacks against encrypted data.

| 2019 | Using context based micro training to develop OER for the benefit of allabstractThis paper demonstrates how Context Based MicroTraining (CBMT) can be used to develop open educational resources in a way that benefits students enrolled in university courses as well as anyone who wants to participate in open-learning activities. CBMT is a framework that provides guidelines for how educational resources should be structured. CBMT stipulates that information should be presented in short sequences and that is relevant for the learner's current situation. In this paper, CBMT is implemented in a practical ICT course using video lectures that are delivered as open educational resources using YouTube. The experiences of enrolled students as well as YouTube users are evaluated as well as the actual results of the enrolled students. The results of the study suggest that users of the video lectures appreciate the learning approach. The actual results, i.e. learning outcomes, of the enrolled students are maintained. The study also demonstrates how using CBMT as open educational resources can free up time for teachers and increase the quality of teaching by benefitting from community feedback.

| 2019 | Understanding passwords - a taxonomy of password creation strategiesabstractPurpose Using authentication to secure data and accounts has grown to be a natural part of computing. Even if several authentication methods are in existence, using passwords remains the most common type of authentication. As long and complex passwords are encouraged by research studies and practitioners alike, computer users design passwords using strategies that enable them to remember their passwords. This paper aims to present a taxonomy of those password creation strategies in the form of a model describing various strategies used to create passwords. Design/methodology/approach The study was conducted in a three-step process beginning with a short survey among forensic experts within the Swedish police. The model was then developed by a series of iterative semi-structured interviews with forensic experts. In the third and final step, the model was validated on 5,000 passwords gathered from 50 different password databases that have leaked to the internet. Findings The result of this study is a taxonomy of password creation strategies presented as a model that describes the strategies as properties that a password can hold. Any given password can be classified as holding one or more of the properties outlined in the model. Originality/value On an abstract level, this study provides insight into password creation strategies. As such, the model can be used as a tool for research and education. It can also be used by practitioners in, for instance, penetration testing to map the most used password creation strategies in a domain or by forensic experts when designing dictionary attacks.
