- Description: The fact that information is ubiquitous throughout most modern organisations cannot be denied. Information is not merely used as an enabler in modern organisations today, but is also used to gain a competitive advantage over competitors. Thus, information has become one of the most important business assets. It is, therefore, imperative that organisations protect information assets as they would protect other business assets. This is typically achieved through implementing various security measures.Technological and procedural security measures are largely dependent on humans. However, the incorrect behaviour of humans poses a significant threat to the protection of these information assets. Thus, it is vital to understand how human behaviour may impact the protection of information assets. While the focus of much literature is on organisations, the focus of this research is on higher education institutions and the factors of information security, with a specific focus on influencing the information security behaviour of computing graduates. Typically, computing graduates would be employed in organisations in various careers such as software developers, network administrators, database administrators and information systems analysts. Employment in these careers means that they would be closely interacting with information assets and information systems. A real problem, as identified by this research, is that currently, many higher education institutions are not consciously doing enough to positively influence the information security behaviour of their computing graduates. This research presents a model to address various factors that could influence the information security behaviour of computing graduates. The aim of this model is to assist computing educators in influencing computing graduates to adopt more secure behaviour, such as security assurance behaviour. A literature review was conducted to identify the research problem. A number of theories such as the Theory of Planned Behaviour, Protection Motivation Theory and Social Cognitive Theory were identified as being relevant for this research as they provided a theoretical foundation for factors that could influence the information security behaviour of computing graduates. Additionally, a survey was conducted to gather the opinions and perceptions of computing educators relating to information security education in higher education institutions. Results indicated that information security is not pervasively integrated within the higher education institutions surveyed. Furthermore, results revealed that most computing students were perceived to not be behaving in a secure manner with regard to information security. This could negatively influence their information security behaviour as computing graduates employed within organisations. Computing educators therefore require assistance in influencing the information security behaviour of these computing students. The proposed model to provide this assistance was developed through argumentation and modelling.

- Description: The Internet is becoming increasingly interwoven in the daily life of many individuals, organisations and nations. It has, to a large extent, had a positive effect on the way people communicate. It has also introduced new avenues for business and has offered nations an opportunity to govern online. Nevertheless, although cyberspace offers an endless list of services and opportunities, it is also accompanied by many risks. One of these risks is cybercrime. The Internet has given criminals a platform on which to grow and proliferate. As a result of the abstract nature of the Internet, it is easy for these criminals to go unpunished. Moreover, many who use the Internet are not aware of such threats; therefore they may themselves be at risk, together with businesses and governmental assets and infrastructure. In view of this, there is a need for cyber security awareness and education initiatives that will promote users who are well versed in the risks associated with the Internet. In this context, it is the role of the government to empower all levels of society by providing the necessary knowledge and expertise to act securely online. However, there is currently a definite lack in South Africa (SA) in this regard, as there are currently no government-led cyber security awareness and education initiatives. The primary research objective of this study, therefore, is to propose a cyber security awareness and education framework for SA that will assist in creating a cyber secure culture in SA among all of its users of the Internet.

- Description: It is commonly held in the literature that users find security and privacy difficult to comprehend. It is also acknowledged that most end-user applications and websites have built-in security and privacy features. Users are expected to interact with these in order to protect their personal information. However, security is generally a secondary goal for users. Considering the complexity associated with security in combination with the notion that it is not users’ primary task, it makes sense that users tend to ignore their security responsibilities. As a result, they make poor security-related decisions and, consequently, their personal information is at risk. Usable Security is the field that investigates these types of issue, focusing on the design of security and privacy features that are usable. In order to understand and appreciate the complexities that exist in the field of Usable Security, the research fields of Human-Computer Interaction and Information Security should be examined. Accordingly, the Information Security field is concerned with all aspects pertaining to the security and privacy of information, while the field of Human-Computer Interaction is concerned with the design, evaluation and implementation of interactive computing systems for human use. This research delivers a framework to evaluate Usable Security in online social networks. In this study, online social networks that are particular to the health domain were used as a case study and contributed to the development of a framework consisting of three components: a process, a validation tool and a Usable Security heuristic evaluation. There is no existing qualitative process that describes how one would develop and validate a heuristic evaluation. In this regard a heuristic evaluation is a usability inspection method that is used to evaluate the design of an interface for any usability violations in the field of Human-Computer Interaction. Therefore, firstly, a new process and a validation tool were required to be developed. Once this had been achieved, the process could then be followed to develop a new heuristic evaluation that is specific to Usable Security. In order to assess the validity of a new heuristic evaluation a validation tool is used. The development of tools that can improve the design of security and privacy features on end-user applications and websites in terms of their usability is critical, as this will ensure that the intended users experience them as usable and can utilise them effectively. The framework for evaluating Usable Security contributes to this objective in the context of online social networks.

- Description: The human being is commonly considered as being the weakest link in information security. Subsequently, as information is one of the most critical assets in an organization today, it is essential that the human element is considered in deployments of information security countermeasures. However, the human element is often neglected in this regard. Consequently, many criminals are now targeting the user directly to obtain sensitive information instead of spending days or even months trying to hack through systems. Some criminals are targeting users by utilizing various social engineering techniques to deceive the user into disclosing information. For this reason, the users of the Internet and ICT-related technologies are nowadays very vulnerable to various social engineering attacks. As a contribution to increase users’ social engineering awareness, a model – called SERUM – was devised. SERUM aims to cultivate social engineering resistance within a community through exposing the users of the community to ‘fake’ social engineering attacks. The users that react incorrectly to these attacks are instantly notified and requested to participate in an online social engineering awareness program. Thus, users are educated on-demand. The model was implemented as a software system and was utilized to conduct a phishing exercise on all the students of the Nelson Mandela Metropolitan University. The aim of the phishing exercise was to determine whether SERUM is effective in cultivating social engineering resistant behaviour within a community. This phishing exercise proved to be successful and positive results emanated. This indicated that a model like SERUM can indeed be used to educate users regarding phishing attacks.

- Description: Information is necessary for any business to function. However, if one does not manage one’s information assets properly then one’s business is likely to be at risk. By implementing Information Security controls, procedures, and/or safeguards one can secure information assets against risks. The risks of an organisation can be mitigated if employees implement safety measures. However, employees are often unable to work securely due to a lack of knowledge. This dissertation evaluates the premise that a computer game could be used to educate employees about Information Security. A game was developed with the aim of educating employees in this regard. If people were motivated to play the game, without external motivation from an organisation, then people would also, indirectly, be motivated to learn about Information Security. Therefore, a secondary aim of this game was to be self-motivating. An experiment was conducted in order to test whether or not these aims were met. The experiment was conducted on a play test group and a control group. The play test group played the game before completing a questionnaire that tested the information security knowledge of participants, while the control group simply completed the questionnaire. The two groups’ answers were compared in order to obtain results. This dissertation discusses the research design of the experiment and also provides an analysis of the results. The game design will be discussed which provides guidelines for future game designers to follow. The experiment indicated that the game is motivational, but perhaps not educational enough. However, the results suggest that a computer game can still be used to teach users about Information Security. Factors that involved consequence and repetition contributed towards the educational value of the game, whilst competitiveness and rewards contributed to the motivational aspect of the game.

- Description: Technological shift has become significant and an area of concern in the health sector with regard to securing health information assets. Health information systems hosting personal health information expose these information assets to ever-evolving threats. This information includes aspects of an extremely sensitive nature, for example, a particular patient may have a history of drug abuse, which would be reflected in the patient’s medical record. The private nature of patient information places a higher demand on the need to ensure privacy. Ensuring that the security and privacy of health information remain intact is therefore vital in the healthcare environment. In order to protect information appropriately and effectively, good information security management practices should be followed. To this end, the International Organization for Standardization (ISO) published a code of practice for information security management, namely the ISO 27002 (2005). This standard is widely used in industry but is a generic standard aimed at all industries. Therefore it does not consider the unique security needs of a particular environment. Because of the unique nature of personal health information and its security and privacy requirements, the need to introduce a healthcare sector-specific standard for information security management was identified. The ISO 27799 was therefore published as an industry-specific variant of the ISO 27002 which is geared towards addressing security requirements in health informatics. It serves as an implementation guide for the ISO 27002 when implemented in the health sector. The publication of the ISO 27799 is considered as a positive development in the quest to improve health information security. However, the question arises whether the ISO 27799 addresses the security needs of the healthcare domain sufficiently. The extensive use of the ISO 27002 implies that many proponents of this standard (in healthcare), now have to ensure that they meet the (assumed) increased requirements of the ISO 27799. The purpose of this research is therefore to conduct a comprehensive comparison of the ISO 27002 and ISO 27799 standards to determine whether the ISO 27799 serves the specific needs of the health sector from an information security management point of view.

A model for integrating information security into the software development life cycle

- Description: It is within highly integrated technology environments that information security is becoming a focal point for designing, developing and deploying software applications. Ensuring a high level of trust in the security and quality of these applications is crucial to their ultimate success. Therefore, information security has become a core requirement for software applications, driven by the need to protect critical assets and the need to build and preserve widespread trust in computing. However, a common weakness that is inherent in the traditional software development methodologies is the lack of attention given to the security aspects of software development. Most of these methodologies do not explicitly include a standardised method for incorporating information security into their life cycles. Meaningful security can be achieved when information security issues are considered as part of a routine development process, and security safeguards are integrated into the software application throughout its life cycle. This, in turn, will lead to users being more confident to use software applications, and to entrust today's computer systems with their personal information. To build better or more secure software, an improved software development process is required. Security of a software application must be based on the risk associated with the application. In order to understand this risk, the relevant information assets need to be identified together with their threats and vulnerabilities. Therefore, security considerations provide input into every phase of the Software Development Life Cycle (SDLC), from requirements gathering to design, implementation, testing and deployment. This research project presents a Secure Software Development Model (SecSDM) for incorporating information security into all phases of the SDLC, from requirements gathering to systems maintenance. The SecSDM is based on many of the recommendations provided by relevant international standards and best practices, for example, the ISO 7498-2 (1989) standard which addresses the underlying security services and mechanisms that form an integral part of the model.

- Description: In most research, appropriate collections of data play a significant role in aiding decision-making processes. This is more critical if the data is being accessed across organisational barriers. Further, for the data to be mined and analysed efficiently, to aid decision-making processes, it must be harnessed in a suitably-structured fashion. There is, for example, a need to perform diverse data analyses and interpretation of structured (non-personal) HIV/AIDS patient-data from various quarters in South Africa. Although this data does exist, to some extent, it is autonomously owned and stored in disparate data storages, and not readily available to all interested parties. In order to put this data to meaningful use, it is imperative to integrate and store this data in a manner in which it can be better utilized by all those involved in the ontological field. This implies integration of (and hence, interoperability), and appropriate accessibility to, the information systems of the autonomous organizations providing data and data-processing. This is a typical problem-scenario for a Virtual Inter-Organisational Information System (VIOIS), proposed in this study. The VIOIS envisaged is a hypothetical, secure, Wireless Grid-enabled Data Warehouse (WGDW) that enables IOIS interaction, such as the storage and processing of HIV/AIDS patient-data to be utilized for HIV/AIDS-specific research. The proposed WDGW offers a methodical approach for arriving at such a collaborative (HIV/AIDS research) integrated system. The proposed WDGW is virtual community that consists mainly of data-providers, service-providers and information-consumers. The WGDW-basis resulted from systematic literaturesurvey that covered a variety of technologies and standards that support datastorage, data-management, computation and connectivity between virtual community members in Grid computing contexts. A Grid computing paradigm is proposed for data-storage, data management and computation in the WGDW. Informational or analytical processing will be enabled through data warehousing while connectivity will be attained wirelessly (for addressing the paucity of connectivity infrastructure in rural parts of developing countries, like South Africa).

Further, for the data to be mined and analysed efficiently, to aid decision-making processes, it must be harnessed in a suitably-structured fashion. There is, for example, a need to perform diverse data analyses and interpretation of structured (non-personal) HIV/AIDS patient-data from various quarters in South Africa. Although this data does exist, to some extent, it is autonomously owned and stored in disparate data storages, and not readily available to all interested parties. In order to put this data to meaningful use, it is imperative to integrate and store this data in a manner in which it can be better utilized by all those involved in the ontological field. This implies integration of (and hence, interoperability), and appropriate accessibility to, the information systems of the autonomous organizations providing data and data-processing. This is a typical problem-scenario for a Virtual Inter-Organisational Information System (VIOIS), proposed in this study. The VIOIS envisaged is a hypothetical, secure, Wireless Grid-enabled Data Warehouse (WGDW) that enables IOIS interaction, such as the storage and processing of HIV/AIDS patient-data to be utilized for HIV/AIDS-specific research. The proposed WDGW offers a methodical approach for arriving at such a collaborative (HIV/AIDS research) integrated system. The proposed WDGW is virtual community that consists mainly of data-providers, service-providers and information-consumers. The WGDW-basis resulted from systematic literaturesurvey that covered a variety of technologies and standards that support datastorage, data-management, computation and connectivity between virtual community members in Grid computing contexts. A Grid computing paradigm is proposed for data-storage, data management and computation in the WGDW. Informational or analytical processing will be enabled through data warehousing while connectivity will be attained wirelessly (for addressing the paucity of connectivity infrastructure in rural parts of developing countries, like South Africa).

- Description: In today’s computing environment, awareness programmes play a much more important role in organizations’ complete information security programmes. Information security awareness programmes are there to change behaviour or reinforce good security practices, and provide a baseline of security knowledge for all information users. Security awareness is a learning process, which changes individual and organizational attitudes and perceptions so that the importance of security and the adverse consequences of its failure are realized. Therefore, with proper awareness, employees become the most effective layer in an organization’s security defence. With the important role that these awareness programmes play in organizations’ complete information security programmes, it is a must that all organizations that are serious about information security must implement it. But though awareness programmes have become increasing important, the level of awareness in most organizations is still low. It seems that the current approach of developing these programmes does not satisfy the needs of most organizations. Therefore, another approach, which tries to meet the needs of most organizations, is proposed in this project as part of the solution of raising the level of awareness programmes in organizations.

- Description: The importance of properly securing an organization’s information and computing resources has become paramount in modern business. Since the advent of the Internet, securing this organizational information has become increasingly difficult. Organizations deploy many security mechanisms in the protection of their data, intrusion detection systems in particular have an increasingly valuable role to play, and as networks grow, administrators need better ways to monitor their systems. Currently, many intrusion detection systems lack the means to accurately monitor and report on wireless segments within the corporate network. This dissertation proposes an extension to the NeGPAIM model, known as NeGPAIM-W, which allows for the accurate detection of attacks originating on wireless network segments. The NeGPAIM-W model is able to detect both wired and wireless based attacks, and with the extensions to the original model mentioned previously, also provide for correlation of intrusion attacks sourced on both wired and wireless network segments. This provides for a holistic detection strategy for an organization. This has been accomplished with the use of Fuzzy logic and neural networks utilized in the detection of attacks. The model works on the assumption that each user has, and leaves, a unique footprint on a computer system. Thus, all intrusive behaviour on the system and networks which support it, can be traced back to the user account which was used to perform the intrusive behavior.

- Description: Information Security is currently viewed from a technical point of view only. Some authors believe that Information Security is a process that involves more than merely Risk Management at the department level, as it is also a strategic and potentially legal issue. Hence, there is a need to elevate the importance of Information Security to a governance level through Information Security Governance and propose a framework to help guide the Board of Directors in their Information Security Governance efforts. IT is a major facilitator of organizational business processes and these processes manipulate and transmit sensitive customer and financial information. IT, which involves major risks, may threaten the security if corporate information assets. Therefore, IT requires attention at board level to ensure that technology-related information risks are within an organization’s accepted risk appetite. However, IT issues are a neglected topic at board level and this could bring about enronesque disasters. Therefore, there is a need for the Board of Directors to direct and control IT-related risks effectively to reduce the potential for Information Security breaches and bring about a stronger system of internal control. The IT Oversight Committee is a proven means of achieving this, and this study further motivates the necessity for such a committee to solidify an organization’s Information Security posture among other IT-related issues.

The cost of free instant messaging: an attack modelling perspective

- Description: Instant Messaging (IM) has grown tremendously over the last few years. Even though IM was originally developed as a social chat system, it has found a place in many companies, where it is being used as an essential business tool. However, many businesses rely on free IM and have not implemented a secure corporate IM solution. Most free IM clients were never intended for use in the workplace and, therefore, lack strong security features and administrative control. Consequently, free IM clients can provide attackers with an entry point for malicious code in an organization’s network that can ultimately lead to a company’s information assets being compromised. Therefore, even though free IM allows for better collaboration in the workplace, it comes at a cost, as the title of this dissertation suggests. This dissertation sets out to answer the question of how free IM can facilitate an attack on a company’s information assets. To answer the research question, the dissertation defines an IM attack model that models the ways in which an information system can be attacked when free IM is used within an organization. The IM attack model was created by categorising IM threats using the STRIDE threat classification scheme. The attacks that realize the categorised threats were then modelled using attack trees as the chosen attack modelling tool. Attack trees were chosen because of their ability to model the sequence of attacker actions during an attack. The author defined an enhanced graphical notation that was adopted for the attack trees used to create the IM attack model. The enhanced attack tree notation extends traditional attack trees to allow nodes in the trees to be of different classes and, therefore, allows attack trees to convey more information. During the process of defining the IM attack model, a number of experiments were conducted where IM vulnerabilities were exploited. Thereafter, a case study was constructed to document a simulated attack on an information system that involves the exploitation of IM vulnerabilities. The case study demonstrates how an attacker’s attack path relates to the IM attack model in a practical scenario. The IM attack model provides insight into how IM can facilitate an attack on a company’s information assets. The creation of the attack model for free IM lead to several realizations. The IM attack model revealed that even though the use of free IM clients may seem harmless, such IM clients can facilitate an attack on a company’s information assets. Furthermore, certain IM vulnerabilities may not pose a great risk by themselves, but when combined with the exploitation of other vulnerabilities, a much greater threat can be realized. These realizations hold true to what French playwright Jean Anouilh once said: “What you get free costs too much”.

There is thus a need for this sector to be well managed, especially with regards to planning, organising, and controlling. Corporate Governance has received a lot of attention in recent times, especially to engender trust on the part of the stakeholders. There are many similarities, but also significant differences in the governance of HE institutions and public companies. Information Technology (IT) plays an extremely important role in the modern organisation, creating huge opportunities, but also increasing the risk to the organisation. Therefore, effective governance of IT in HE Institutions is of great importance.

- Description: Information security is crucial to the continuous well-being of modern orga- nizations. Humans play a signfiicant role in the processes needed to secure an organization's information resources. Without an adequate level of user co-operation and knowledge, many security techniques are liable to be misused or misinterpreted by users. This may result in an adequate security measure becoming inadequate. It is therefor necessary to educate the orga- nization's employees regarding information security and also to establish a corporate sub-culture of information security in the organization, which will ensure that the employees have the correct attitude towards their security responsibilities. Current information security education programs fails to pay su±cient attention to the behavioral sciences. There also exist a lack of knowledge regarding the principles, and processes, that would be needed for the establishment of an corporate sub-culture, specific to information security. Without both the necessary knowledge, and the desired attitude amongst the employee, it will be impossible to guarantee that the organi- zation's information resources are secure. It would therefor make sense to address both these dimensions to the human factor in information security, using a single integrated, holistic approach. This dissertation presents such an approach, which is based on an integration of sound behavioral theories.

Introducing hippocratic log files for personal privacy control

- Description: The rapid growth of the Internet has served to intensify existing privacy concerns of the individual, to the point that privacy is the number one concern amongst Internet users today. Tools exist that can provide users with a choice of anonymity or pseudonymity. However, many Web transactions require the release of personally identifying information, thus rendering such tools infeasible in many instances. Since it is then a given that users are often required to release personal information, which could be recorded, it follows that they require a greater degree of control over the information they release. Hippocratic databases, designed by Agrawal, Kiernan, Srikant, and Xu (2002), aim to give users greater control over information stored in a data- base. Their design was inspired by the medical Hippocratic oath, and makes data privacy protection a fundamental responsibility of the database itself. To achieve the privacy of data, Hippocratic databases are governed by 10 key privacy principles. This dissertation argues, that asides from a few challenges, the 10 prin- ciples of Hippocratic databases can be applied to log ¯les. This argument is supported by presenting a high-level functional view of a Hippocratic log file architecture. This architecture focuses on issues that highlight the con- trol users gain over their personal information that is collected in log files. By presenting a layered view of the aforementioned architecture, it was, fur- thermore, possible to provide greater insight into the major processes that would be at work in a Hippocratic log file implementation. An exploratory prototype served to understand and demonstrate certain of the architectural components of Hippocratic log files. This dissertation, thus, makes a contribution to the ideal of providing users with greater control over their personal information, by proposing the use of Hippocratic logfiles.
