Design and implementation of a prototype to include security activities as part of application systems designKasselman, André 20 November 2014 (has links)
M.Com. (Information systems) / This study has its origin in the growing need for information systems to be classified as 'secure'. With the increasing use of Computer Aided Software Engineering (CASE) tools in the design of application systems for commercial use, the risks that exist in terms of information security have become more prominent. The importance of considering security during the analysis and design of an information system, in other words, on a logical level, is increasing daily. Usually security features are added to existing application systems on an ad hoc basis. Security design activities should become such an integrated part of systems analysis and design activities on a logical level, that a complete integration of the two fields, security and computer aided software engineering, can be achieved. The aim of this dissertation is to study the literature to discover existing approaches to this integration, and to extract the strengths from them and expand on those strengths in order to compile an approach that is completely implementable in the form of a prototype data flow design tool (DFD tool). The proposed approach to the secure analysis and design of an application system of a logical level, which is presented in Chapter 4, is designed in conjunction with H.A.S. Booysen [Booysen, Kasselman, Eloff - 1994]. Existing CASE-tools have also been studied by the author to determine their current capabilities, especially in terms of security definition activities, but also in terms of their support to the systems analyst during the analysis and design phases of the project life cycle when developing a target application system.

'n Model vir inligtingsekerheidsdokumentasieDu Toit, Louisa Maria 20 November 2014 (has links)
M.Sc. (Informatics) / A need has been identified for guidelines to Top Management on the implementation of an Information Security Policy and its associated documentation. In this dissertation, the Model for Information Security Documentation (lSD-model) for the organisation and content of documentation on information security is proposed. The proposed model is divided into three distinct levels respectively containing the Information Security Policy Document, the Goal Documents and the Application Guideline Documents. A document is placed on the different levels of the ISO-model according to the amount of detailed information it contains and the management level mainly concerned with that document. Guidelines are given regarding the content and format of each of the levels. Particular emphasis is laid on the Information Security Policy Document, which is the highest level, and a number of existing Information Security Policy Documents are evaluated according to the guidelines given for the lSD-model. Finally, a comparison is made between C. C. Wood's guidelines on Information Security Policies and those given for the ISO-model.

Protection of security information within government departments in South AfricaNkwana, Mokata Johannes 02 1900 (has links)
The protection of security information in government departments requires the active engagement of executive management to assess emerging threats and provide strong security risk control measures. For most government departments, establishing effective protection of security information is a major initiative, given the often continuous, strategic nature of typical security efforts. This requires commitments or support from senior management and adequate resources. It necessitates the elevation of information security management to positions of authority commensurate to the required responsibilities. This has been the trend in recent years as government departments are increasingly dependent on their information assets and resources, while threats and disruptions continue to escalate in frequency and cost. It is clear from numerous recent studies that organisations that have taken the steps described in this research document and have implemented effective information security risk control measures have achieved significant results in reduced losses and improved resource management. Given the demonstrable benefits, it is surprising that there have not been greater progress in effectively managing information assets. Although regulatory compliance has been a major driver in improving the protection of security information overall, this study has also shown that nearly half of all government departments are failing to initiate meaningful compliance efforts. Failure to address the identified vulnerabilities by government departments will result in espionage, covert influencing manipulation, fraud, sabotage and corruption. Information security risk control measures include the elements required to provide senior management assurance that its direction and intent are reflected in the security posture of the organisation by utilising a structured approach to implement an information security programme. Once those elements are in place, senior management can be confident that adequate and effective protection of security information will protect, as far as possible, the department’s vital information assets. / Criminology and Security Science / M.

Information security issues facing internet café users.Kgopa, Alfred Thaga. January 2013 (has links)
M. Tech. Business Information Systems / Although owners of Internet cafés extend the freedom to have Internet access to the community, they fail to tighten their computer security to safeguard the private information of their customers. This dissertation provides a conceptual framework for improving information security in the Internet Café, to help and ensure data privacy, data integrity, risk management and information security (IS) behaviour. The study investigated the information security issues that are faced by users of Internet cafés and explored the effects of these issues. The framework shows how users can improve their physical security to reach higher standards of information privacy over the Internet.

Visualisation of PF firewall logs using open sourceCoetzee, Dirk January 2015 (has links)
If you cannot measure, you cannot manage. This is an age old saying, but still very true, especially within the current South African cybercrime scene and the ever-growing Internet footprint. Due to the significant increase in cybercrime across the globe, information security specialists are starting to see the intrinsic value of logs that can ‘tell a story’. Logs do not only tell a story, but also provide a tool to measure a normally dark force within an organisation. The collection of current logs from installed systems, operating systems and devices is imperative in the event of a hacking attempt, data leak or even data theft, whether the attempt is successful or unsuccessful. No logs mean no evidence, and in many cases not even the opportunity to find the mistake or fault in the organisation’s defence systems. Historically, it remains difficult to choose what logs are required by your organization. A number of questions should be considered: should a centralised or decentralised approach for collecting these logs be followed or a combination of both? How many events will be collected, how much additional bandwidth will be required and will the log collection be near real time? How long must the logs be saved and what if any hashing and encryption (integrity of data) should be used? Lastly, what system must be used to correlate, analyse, and make alerts and reports available? This thesis will address these myriad questions, examining the current lack of log analysis, practical implementations in modern organisation, and also how a need for the latter can be fulfilled by means of a basic approach. South African organizations must use technology that is at hand in order to know what electronic data are sent in and out of their organizations network. Concentrating only on FreeBSD PF firewall logs, it is demonstrated within this thesis the excellent results are possible when logs are collected to obtain a visual display of what data is traversing the corporate network and which parts of this data are posing a threat to the corporate network. This threat is easily determined via a visual interpretation of statistical outliers. This thesis aims to show that in the field of corporate data protection, if you can measure, you can manage.

Cybersecurity framework for cloud computing adoption in rural based tertiary institutionsPatala, Najiyabanu Noormohmed 18 May 2019 (has links)
MCom (Business Information Systems) / Department of Business Information Systems / Although technology is being progressively used in supporting student learning and enhancing business processes within tertiary institutions, certain aspects are hindering the decisions of cloud usage. Among many challenges of utilizing cloud computing, cybersecurity has become a primary concern for the adoption. The main aim of the study was to investigate the effect of cloud cyber-security usage at rural based tertiary institutions in order to compare the usage with an urban-based institution and propose a cybersecurity framework for adoption of cloud computing cybersecurity. The research questions focused on determining the drivers for cloud cybersecurity usage; the current adoption issues; how cybersecurity challenges, benefits, and quality affects cloud usage; the adoption perceptions and awareness of key stakeholders and identifying a cloud cybersecurity adoption framework. A quantitative approach was applied with data collected from a simple random sample of students, lecturers, admin and IT staff within the tertiary institutions through structured questionnaires.
The results suggested compliance with legal law as a critical driver for cloud cybersecurity adoption. The study also found a lack of physical control of data and harmful activities executed on the internet as challenges hampering the adoption. Prevention of identity fraud and cheaper security costs were identified as benefits of adoption. Respondents found cloud cybersecurity to be accurate and effective, although most of the students and employees have not used it. However, respondents were aware of the value of cybersecurity adoption and perceive for it to be useful and convenient, hence have shown the intention of adopting it. There were no significant elements identified to differentiate the perceptions of usage at rural and urban-based tertiary institutions. The results of the study are to be used for clarifying the cybersecurity aspects of cloud computing and forecasting the suitability cloud cybersecurity within the tertiary institutions. Recommendations were made on how tertiary institutions and management can promote cloud cybersecurity adoption and how students, lecturers, and staff can effectively use cloud cybersecurity. / NRF

A validated information privacy governance questionnaire to measure the perception of how effective privacy is governed in a financial institution in the South African contextSwartz, Paulus 04 1900 (has links)
The general aim of this research is to develop a conceptual privacy governance framework (CPGF) that can be used to develop a valid and reliable information privacy governance questionnaire (IPGQ) to assess the perception of employees of how effective the organisation governs privacy.
The CPGF was developed to incorporate a comprehensive set of privacy components that could assist management in governing privacy across an organisation. IPGQ statements were derived from the theory of the sub-components of CPGF, evaluated by an expert panel and pre-tested by a pilot group. A quantitative mono method research was followed using a survey questionnaire to collect data in a financial institution in South Africa. Exploratory Factor Analysis (EFA) was used to determine the underlying factorial structure and the Cronbach Alpha was used to establish the internal reliability of the factors. From the initial item reduction of the constructs, four factors were derived to test the privacy perception of employees. The IPGQ consisted of 49 valid and reliable questions. One-way Analysis of Variance (ANOVA) was used, and three significant differences were discovered among the demographical groups for the age groups and two for the employment status groups (organisational commitment and privacy controls).
The CPGF and IPGQ can aid organisations to determine if organisations are effectively governing the privacy in the organisations in order to assist them in meeting the accountability condition of the Protection of Personal Information Act (POPIA). / Computing / M. Sc. (Information Systems)
