“This is the way ‘I’ create my passwords ...":does the endowment effect deter people from changing the way they create their passwords?

The endowment effect is the term used to describe a phenomenon that manifests as a reluctance to relinquish owned artifacts, even when a viable or better substitute is offered. It has been confirmed by multiple studies when it comes to ownership of physical artifacts. If computer users also "own", and are attached to, their personal security routines, such feelings could conceivably activate the same endowment effect. This would, in turn, lead to their over-estimating the \value" of their existing routines, in terms of the protection they afford, and the risks they mitigate. They might well, as a consequence, not countenance any efforts to persuade them to adopt a more secure routine, because their comparison of pre-existing and proposed new routine is skewed by the activation of the endowment effect.In this paper, we report on an investigation into the possibility that the endowment effect activates when people adopt personal password creation routines. We did indeed find evidence that the endowment effect is likely to be triggered in this context. This constitutes one explanation for the failure of many security awareness drives to improve password strength. We conclude by suggesting directions for future research to confirm our findings, and to investigate the activation of the effect for other security routines

Evaluating the Usability of a Multilingual Passphrase Policy

The literature shows that users struggle to generate secure passwords. This has led to systems administrators implementing password expiry policies that burden and frustrate users. This study explores the security and usability of a multilingual passphrase policy, as multilingualism has the potential to enhance security. A total of 224 participants were invited to participate in an experiment to generate and recall short passwords and multilingual passphrases. The findings of this study show that, although a multilingual passphrase policy made passphrase generation slightly more difficult, its use motivated users to generate unique memorable passphrases. Arguably, repeated use of passphrases promotes memorability and cognitive fluency. Furthermore, the multilingual passphrases in this study proved to be stronger than those reported in the literature

Children's password-related books:efficacious, vexatious and incongruous

Software is developed specifically for children and this often requires them to authenticate themselves, usually by entering a password. Password hygiene is important for children, because the principles they learn in early life will often endure across their life span. Children learn from their parents, siblings, teachers, and peers. They also learn from educational resources, such as children’s books. We carried out a content analysis of a range of children’s books that aims to educate children about passwords. We used directional coding, as informed by a systematic literature review of methods, such as those used in other content analysis-based studies of children’s books. We examined the principles the books taught, and whether these were correct. We also analysed how the books portrayed the genders of characters, in various roles. We found that principle coverage was variable, with books sometimes teaching outdated principles. Genders were evenly represented in the books. Finally, our analysis revealed conflation of the terms “safety” and “security” in the cyber domain. We conclude the paper by justifying the adjectives we use in the title.</p

Accessible and inclusive cyber security:a nuanced and complex challenge

It has been argued that human-centred security design needs to accommodate the considerations of three dimensions: (1) security, (2) usability and (3) accessibility. The latter has not yet received much attention. Now that governments and health services are increasingly requiring their citizens/patients to use online services, the need for accessible security and privacy has become far more pressing. The reality is that, for many, security measures are often exasperatingly inaccessible. Regardless of the outcome of the debate about the social acceptability of compelling people to access public services online, we still need to design accessibility into these systems, or risk excluding and marginalising swathes of the population who cannot use these systems in the same way as abled users. These users are particularly vulnerable to attack and online deception not only because security and privacy controls are inaccessible but also because they often struggle with depleted resources and capabilities together with less social, economic and political resilience. This conceptual paper contemplates the accessible dimension of human-centred security and its impact on the inclusivity of security technologies. We scope the range of vulnerabilities that can result from a lack of accessibility in security solutions and contemplate the nuances and complex challenges inherent in making security accessible. We conclude by suggesting a number of avenues for future work in this space.</p

Risk as affect:the affect heuristic in cybersecurity

Risk perception is an important driver of netizens’ (Internet users’) cybersecurity behaviours, with a number of factors influencing its formation. It has been argued that the affect heuristic can be a source of variation in generic risk perception. However, a major shortcoming of the supporting research evidence for this assertion is that the central construct, affect, has not been measured or analysed. Moreover, its influence in the cybersecurity domain has not yet been tested. The contribution of the research reported in this paper is thus, firstly, to test the affect heuristic while measuring its three constructs: affect, perceived risk and perceived benefit and, secondly, to test its impact in the cybersecurity domain. By means of two carefully designed studies (N = 63 and N = 233), we provide evidence for the influence of the affect heuristic on risk perception in the cybersecurity domain. We conclude by identifying directions for future research into the role of affect and its impact on cybersecurity risk perception

MIGRANT : modeling smartphone password manager adoption using migration theory

Password manager applications have the potential to alleviate password pain and improve password strength, yet they are not widely adopted. Password managers are dissimilar to other kinds of software tools, given that the leakage of the credentials they store could give a hacker access to all the individual's online accounts. Moreover, adoption requires a deliberate switch away from an existing (manual) password management routine. As such, traditional technology adoption models are unlikely to model password manager adoption accurately. In this paper, we propose and explain how we validated a theoretical model of smartphone password manager adoption. We commenced by carrying out exploratory interviews with 30 smartphone owners to identify factors that influence adoption. These were used to develop a model that reflects the password manager adoption process, building on migration theory. The proposed model, MIGRANT (MIGRation pAssword maNager adopTion), was validated and subsequently refined in a week-long study with 198 smartphone owners, combining self-report and observation to measure constructs. This study contributes to the information security behavioral literature by isolating the main factors that encourage or deter password manager adoption, and those that moor smartphone owners in their current practices, hindering switching. With this investigation, we introduce migration theory as a reference theory for future studies in the information security behavioral field

Strategies to Reduce Small Business Data Security Breaches

Organizations affected by data security breaches may experience reputational damage and remediation costs. Understanding the data security strategies needed to protect small businesses is vital to safeguard company data and protect consumers’ personal information. Grounded in systems theory, the purpose of this qualitative multiple case study was to explore the strategies small business owners use to reduce data security breaches. The participants were 4 small business owners located in the southern region of the United States: 2 franchise small business owners and 2 nonfranchise small business owners. Data were collected from semistructured interviews and organizational documents. Yin’s 5-step data analysis was used to analyze the data. Two themes emerged: information assurance and third-party dependencies. A key recommendation includes small business owners implementing a contingency plan to manage a data security breach. The implications of positive social change include the potential for small business owners to develop data security strategies to protect their organizations from experiencing a data breach. Protection from data breaches can, in turn, rebuild trust with small business owners and increase spending, increasing the local community’s tax base that may be used to improve social services in the local community

A model for secure and usable passphrases for multilingual users

Research on more than 100 million passwords that have been leaked to the public domain has uncovered various security limitations associated with user-generated short passwords. Long passwords (passphrases) are considered an alternative solution that could provide a balance between security and usability. However, the literature shows a lack of consistency in the security and usability contributions of passphrases. For example, studies that investigated passphrase security focusing on structural dependencies at character level found passphrases to be secure. Inversely, other research findings suggest that passphrase security could be compromised by the use of predictable grammatical rules, popular words in a natural language and keyboard patterns. This is further exacerbated by research on passphrases that is focused on the Global North. This is a huge concern given that results from inter-cultural studies suggest that local languages do influence password structure and to some extent, password usability and security. To address these gaps in the literature, this study used socio-technical theory which emphasised both the social and technical aspects of the phenomenon under study. Psychological studies show that the memory has limited capacity, something that threatens password usability; hence, the need to utilise information that is already known during password generation. Socio-cultural theory suggests that the information that is already known by users is contextually informed, hence sociocultural theory was applied to understand the contextual factors that could be used to enhance passphrase security and usability. With reference to the Southern African context, this study argues that system designers should take advantage of a multilingual user group and encourage the generation of passphrases that are based on substrings from different languages. This study went on to promote the use of multilingual passphrases instead of emphasising multi-character class passwords. This study was guided by design science research. Participants were invited to take part in a short password and multilingual passphrase generation and recall experiment that was made available using a web-based application. These passwords were generated by participants under pre-specified conditions. Quantitative and qualitative data was gathered. The study findings showed the use of both African and Indo-European languages in multilingual passphrases and short passwords. English oriented passwords and substrings dominated the multilingual passphrase and short password corpora. In addition, some of the short passwords and substrings in the multilingual passphrase corpora were found among the most common passwords of 2016, 2017 and 2018. Usability tests showed that multilingual passphrases are usable, even though they were not easy to create and recall when compared to short passwords. A high rate of password reuse during short password generation by participants might have worked in favour of short passwords. Nonetheless, participants appear to reflect better usability with multilingual passphrases over time due to repeated use. Females struggled to recall short passwords and multilingual passphrases when compared to their male counterparts. Security tests using the Probabilistic Context-Free Grammar suggest that short passwords are weaker, with just more than 50% of the short passwords being guessed, while none 4 Final Submission of Thesis, Dissertation or Research Report/Project, Conference or Exam Paper of the multilingual passphrases were guessed. Further analysis showed that short passwords that were oriented towards an IndoEuropean language were more easily guessed than African language-oriented short passwords. As such, this study encourages orienting passwords towards African languages while the use of multilingual passphrases is expected to offer more security. The use of African languages and multilingual passphrases by a user group that is biased towards English-oriented passwords could enhance security by increasing the search space
