2024 Using the theory of interpersonal behaviour to explain employees' cybercrime preventative behaviour during the pandemic
abstract
Purpose The COVID-19 pandemic necessitated a significant shift in how employees executed their professional responsibilities. Concurrently, the incidence of cybercrime experienced a noteworthy surge due to the increased utilisation of cyberspace. The abrupt transition to telecommuting altered the interpersonal dynamics inherent in traditional work environments. This paper aims to examine the impact of interpersonal factors on the cybercrime preventative measures adopted by telecommuting employees. Design/methodology/approach A conceptual model, grounded in the Theory of Interpersonal Behaviour, is evaluated through an online survey. The data set comprises responses from 209 employees in South Africa, and the analysis uses partial least squares structural equation modelling. Findings The results reveal substantial predictive power to explain cybercrime preventative behaviours. Notably, the study underscores the significant influence of habit and affect on intention and subsequent behaviour. Practical implications The results suggest that practitioners should give due attention to emotional dimensions (affect) as a catalyst for information security behaviour. The formulation of employees’ information security responsibilities should be pragmatic, fostering subconscious compliance to establish routine behaviour (habit). Originality/value This research underscores the pivotal roles played by habit and emotions in shaping behavioural patterns related to information security. Furthermore, it provides researchers with an illustrative model for operationalising these constructs within the realm of security. The results contribute additional perspectives on the repercussions of the COVID-19 pandemic on cybercrime preventative behaviours.

2023 Risk homeostasis and security fatigue: a case study of data specialists
abstract
Purpose Organisations use a variety of technical, formal and informal security controls but also rely on employees to safeguard information assets. This relies heavily on compliance and constantly challenges employees to manage security-related risks. The purpose of this research is to explore the homeostatic mechanism proposed by risk homeostasis theory (RHT), as well as security fatigue, in an organisational context. Design/methodology/approach A case study approach was used to investigate the topic, focusing on data specialists who regularly work with sensitive information assets. Primary data was collected through semi-structured interviews with 12 data specialists in a large financial services company. Findings A thematic analysis of the data revealed risk perceptions, behavioural adjustments and indicators of security fatigue. The findings provide examples of how these concepts manifest in practice and confirm the relevance of RHT in the security domain. Originality/value This research illuminates homeostatic mechanisms in an organisational security context. It also illustrates links with security fatigue and how this could further impact risk. Examples and indicators of security fatigue can assist organisations with risk management, creating “employee-friendly” policies and procedures, choosing appropriate technical security solutions and tailoring security education, training and awareness activities.

2021 Accessible authentication: dyslexia and password strategies
abstract
Purpose The purpose of this paper is to reveal the lived experiences of dyslexics in engaging with all kinds of alphanumeric authentication mechanisms. Design/methodology/approach A significant proportion of the world’s population experiences some degree of dyslexia, which can lead to spelling, processing, sequencing and retention difficulties. Passwords, being essentially sequences of alphanumeric characters, make it likely that dyslexics will struggle with these, even more so than the rest of the population. Here, this study explores the difficulties people with dyslexia face, their general experiences with passwords, the coping strategies they use and the advice they can provide to developers and others who struggle with passwords. This paper collects empirical data through semi-structured interviews with 13 participants. Thematic analysis was used to provide an in-depth view of each participant’s experience. Findings The main contribution of this paper is to provide evidence related to the inaccessibility dimensions of passwords as an authentication mechanism, especially for dyslexics and to recommend a solution direction. Research limitations/implications There is a possible volunteer bias, as this study is dealing with self-reported data including historical and reflective elements and this paper is seeking information only from those with self-declared or diagnosed dyslexia. Furthermore, many expressed interest or curiosity in the relationship between dyslexia and password difficulties, for some a motivation for their participation. Finally, given that the participants told us that dyslexics might hide, it is possible that the experiences of those who do hide are different from those who chose to speak to us and thus were not hiding. Originality/value A few authors have written about the difficulties dyslexics face when it comes to passwords, but no one has asked dyslexics to tell them about their experiences. This paper fills that gap.
