- Description: The World Health Organization has recommended Telemedicine to improve health care in developing countries. The objective of this study was to produce Critical Success Factors that will investigate and identify factors that influence the acceptance and continued use of Telemedicine in the Eastern Cape Department of Health, and to suggest ways to sustain this technology from initial adoption (the pilot programme) to full adoption. Sub questions investigated which other facilitating factors, such as management support or previous Information Technology exposure must be present in order for the technology to be adopted successfully. The study made use of a questionnaire to investigate the user acceptance and behaviour of health care workers. A return rate of 76% was achieved. The data was analysed making use of Statistical Package for the Social Sciences (SPSS), specifically the Chi Square test. From these results Critical Success Factors where then formulated to address the problems identified. The Critical Success Factors that were identified include: Implement and disseminate best practice within a legislative framework; Find a champion; Change management strategies; Training; Sustainable finance; Technical issues and Project management principles If these CSFs are addressed before and during the implementation of Telemedicine it will increase the acceptance and use of the technology among health care workers.

- Description: E-mails have become the standard for business as well as personal communication. The inherent security risks within e-mail communication present the problem of anonymity. If an author of an e-mail is not known, the digital forensic investigator needs to determine the authorship of the e-mail using a process that has not been standardised in the e-mail forensic field. This research project examines many problems associated with e-mail communication and the digital forensic domain; more specifically e-mail forensic investigations, and the recovery of legally admissible evidence to be presented in a court of law. The Research Methodology utilised a comprehensive literature review in combination with Design Science which results in the development of an artifact through intensive research. The Proposed E-Mail Forensic Methodology is based on the most current digital forensic investigation process and further validation of the process was established via expert reviews. The opinions of the digital forensic experts were an integral portion of the validation process which adds to the credibility of the study. This was performed through the aid of the Delphi technique. This Proposed E-Mail Forensic Methodology adopts a standardised investigation process applied to an e-mail investigation and takes into account the South African perspective by incorporating various checks with the laws and legislation. By following the Proposed E-mail Forensic Methodology, e-mail forensic investigators can produce evidence that is legally admissible in a court of law.

- Description: E-Commerce has been plagued with problems since its inception and this study examines one of these problems: The lack of user trust in E-Commerce created by the risk of phishing. Phishing has grown exponentially together with the expansion of the Internet. This growth and the advancement of technology has not only benefited honest Internet users, but has enabled criminals to increase their effectiveness which has caused considerable damage to this budding area of commerce. Moreover, it has negatively impacted both the user and online business in breaking down the trust relationship between them. In an attempt to explore this problem, the following was considered: First, E-Commerce’s vulnerability to phishing attacks. By referring to the Common Criteria Security Model, various critical security areas within E-Commerce are identified, as well as the areas of vulnerability and weakness. Second, the methods and techniques used in phishing, such as phishing e-mails, websites and addresses, distributed attacks and redirected attacks, as well as the data that phishers seek to obtain, are examined. Furthermore, the way to reduce the risk of phishing and in turn increase the trust between users and websites is identified. Here the importance of Trust and the Uncertainty Reduction Theory plus the fine balance between trust and control is explored. Finally, the study presents Critical Success Factors that aid in phishing prevention and control, these being: User Authentication, Website Authentication, E-mail Authentication, Data Cryptography, Communication, and Active Risk Mitigation.

- Description: The Internet has made a considerable impact on how business is conducted. Empowered by technology consumers are using the Internet as a tool to communicate and transact online. E-commerce (electronic commerce) presents opportunities for business to gain a competitive advantage, however it also posses certain challenges. Small and Medium Hospitality Enterprises (SMHEs) sector within the tourism industry, is one of the sectors which stands to benefit from using the Internet for business. Researchers agree that the contribution made by the tourism sector in developing economies is substantial. However, SMHEs are noted for their failure to derive optimal benefits from using the Internet for business to improve their competitiveness. This study which seeks to develop a model for use by SMHEs as a guide when making the decision to adopt technology was necessitated by the importance of SMHE’s contribution in the economy of developing countries. This model is based on the examination of existing theories and models such as; the Delone and McLean IS success model (2004), and the ITGI’s (2007) IT governance focus areas model. To elicit the desired outcomes, additional data was collected using questionnaires, interviews, and observations. The collected data was analysed and resulted in the development of a model that can be used by SMHEs in order to derive value from IT and to gain a competitive advantage.
