    The password practices applied by South African online consumers : perception versus reality
    (AOSIS Publishing, 2015-07) Butler, Rika; Butler, Martin
    Background: The ability to identify and authenticate users is regarded as the foundation of computer security. Although new authentication technologies are evolving, passwords are the most common method used to control access in most computer systems. Research suggests that a large portion of computer security password breaches are the result of poor user security behaviour. The password creation and management practices that online consumers apply have a direct effect on the level of computer security and are often targeted in attacks. Objectives: The objective of this study was to investigate South African online consumers’ computer password security practices and to determine whether consumers’ perceptions regarding their password security ability is reflected in the password creation and management practices that they apply. Method: A Web-based survey was designed to (1) determine online consumers’ perceptions of their skills and competence in respect of computer password security and (2) determine the practices that South African online consumers apply when creating and managing passwords. The measures applied were then compared to (1) the users’ perceptions about their computer password security abilities and (2) the results of international studies to determine agreement and inconsistencies. Results: South African online consumers regard themselves as proficient password users. However, various instances of unsafe passwords practices were identified. The results of this South African study correspond with the results of various international studies confirming that challenges to ensure safe online transacting are in line with international challenges. Conclusion: There is a disparity between South African online consumers’ perceived ability regarding computer password security and the password creation and management practices that they apply.

    Some password users are more equal than others : towards customisation of online security initiatives
    (AOSIS Publishing, 2018) Butler, Rika; Butler, Martin
    Background: Online security is a growing concern and user authentication through passwords remains an important mechanism to protect online assets. Research to date has highlighted the need to address human behaviour but without an indication of where the emphasis of security education, training and awareness (SETA) initiatives should be, beyond improved password practices. Objectives: The aim of this study was to, through analysis of the password behaviour of South African online consumers: (1) understand the prevalence of poor password practices among consumers overall and (2) identify specific password deficiencies prevalent among different demographic groups to be focus areas for tailored intervention programmes. Method: The study uses a quantitative research approach. An online survey was used to gather demographic data, perceptions about online security and applied password practices. A sample of 737 valid responses was analysed for this research. Results: Based on the descriptive analysis of the responses three key observations were made. Firstly, there is a distinct difference in the incidence of poor password practices for all respondents and thus support for tailored interventions. Secondly, there are variances between the practices within different demographic groups that could be used for customisation of interventions. Finally, the different poor practices cannot be uniquely attributed to one particular set of demographics. Conclusion: The study concluded that to improve computer password security in South Africa, password SETA programmes should be customised for areas where individual needs exist and not merely per password practice or demographic group.
