    An Analysis of Cyber-Incidents in South Africa
    (2017-12-23) Van Niekerk, Brett
    Cybersecurity concerns are present in all nations, but the exact nature of the threats differs depending on the country and/or region. Therefore there is a need to assess the threats and impacts for specific countries. This article presents a high-level analysis of “newsworthy” cyber-incidents that affected South Africa. The 54 incidents that are considered are categorised according to impact type, perpetrator type, and victim type, and the trends are assessed. It was found that the most common impact type was data exposure, which was also one that had increased noticeably in recent years. The most prevalent perpetrator type was found to be hacktivists, which had also exhibited a recent increase in activity. A particularly concerning trend was the recent high number of incidents of data exposure caused by error, a trend running contrary to the drive to improve cybersecurity. It was also found that of the incidents considered, 54% targeted state-owned or political entities as victims. In general, the results appeared consistent with global reported trends.

    Students’ Cybersecurity Awareness at a Private Tertiary Educational Institution
    (2017-12-23) Chandarman, Rajesh; Van Niekerk, Brett
    Internet-based attacks have become prevalent and are expected to increase as technology ubiquity increases. Consequently, cybersecurity has emerged as an essential concept in everyday life. Cybersecurity awareness (CSA) is a key defence in the protection of people and systems. The research presented in this article aimed to assess the levels of CSA among students at a private tertiary education institution in South Africa. A questionnaire tested students in terms of four variables: cybersecurity knowledge; self-perception of cybersecurity skills, actual cybersecurity skills and behaviour; and cybersecurity attitudes. The responses revealed several misalignments, including instances of “cognitive dissonance” between variables, which make the students potentially vulnerable to cyber-attacks. The findings demonstrate the need for targeted CSA campaigns that address the specific weaknesses of particular populations of users.
