- Description: In today’s business world, information has become the driving force of organizations. With organizations transmitting large amounts of information to various geographical locations, it is imperative that organizations ensure the protection of their valuable commodity. Organizations should ensure that only authorized individuals receive, view and alter the information. This is also true to Higher Education Institutions (HEIs), which need to protect its examination papers, amongst other valuable information. With various threats waiting to take advantage of the examination papers, HEIs need to be prepared by equipping themselves with an information security management system (ISMS), in order to ensure that the process of setting examination papers is secure, and protects the examination papers within the process. An ISMS will ensure that all information security aspects are considered and addressed in order to provide appropriate and adequate protection for the examination papers. With the assistance of information security concepts and information security principles, the ISMS can be developed, in order to secure the process of preparing examination papers; in order to protect the examination papers from potential risks. Risk assessment form part of the ISMS, and is at the centre of any security effort; reason being that to secure an information environment, knowing and understanding the risks is imperative. Risks pertaining to that particular environment need to be assessed in order to deal with those appropriately. In addition, very important to any security effort is ensuring that employees working with the valuable information are made aware of these risks, and can be able to protect the information. Therefore, the role players (within the examination paper preparation process (EPPP)) who handle the examination papers on a daily basis have to be equipped with means of handling valuable information in a secure manner. Some of the role players’ behaviour and practices while handling the information could be seen as vulnerabilities that could be exploited by threats, resulting in the compromise in the CIA of the information. Therefore, it is imperative that role players are made aware of their practices and iv behaviour that could result in a negative impact for the institution. This awareness forms part and is addressed in the ISMS.

- Description: The motivation for this study argued that current information security ed- ucation systems are inadequate for educating all users of computer systems world wide in acting securely during their operations with information sys- tems. There is, therefore, a pervasive need for information security knowledge in all aspects of modern life. E-Learning 2.0 could possi- bly contribute to solving this problem, however, little or no knowledge currently exists regarding the suitability and practicality of using such systems to infer information security knowledge to learners.

- Description: Today, one is expected to remember multiple user names and passwords for different domains when one wants to access on the Internet. Identity management seeks to solve this problem through creating a digital identity that is exchangeable across organisational boundaries. Through the setup of collaboration agreements between multiple domains, users can easily switch across domains without being required to sign in again. However, use of this technology comes with risks of user identity and personal information being compromised. Criminals make use of spoofed websites and social engineering techniques to gain illegal access to user information. Due to this, the need for users to be protected from online threats has increased. Two processes are required to protect the user login information at the time of sign-on. Firstly, user’s information must be protected at the time of sign-on, and secondly, a simple method for the identification of the website is required by the user. This treatise looks at the process for identifying and verifying user information, and how the user can verify the system at sign-in. Three models for identity management are analysed, namely the Microsoft .NET Passport, Liberty Alliance Federated Identity for Single Sign-on and the Mozilla TrustBar for system authentication.

- Description: Over the past few decades the field of computing has grown and evolved. In this time, information security research has experienced the same type of growth. The increase in importance and interest in information security research is reflected by the sheer number of research efforts being produced by different type of organizations around the world. One such organization is the International Federation for Information Processing (IFIP), more specifically the IFIP Technical Committee 11 (IFIP TC11). The IFIP TC11 community has had a rich history in producing high quality information security specific articles for over 20 years now. Therefore, IFIP TC11 found it necessary to reflect on this history, mainly to try and discover where it came from and where it may be going. Its 20th anniversary of its main conference presented an opportunity to begin such a study of its history. The core belief driving the study being that the future can only be realized and appreciated if the past is well understood. The main area of interest was to find out topics which may have had prevalence in the past or could be considered as "hot" topics. To achieve this, the author developed a systematic process for the study. The underpinning element being the creation of a classification scheme which was used to aid the analysis of the IFIP TC11 20 year's worth of articles. Major themes were identified and trends in the series highlighted. Further discussion and reflection on these trends were given. It was found that, not surprisingly, the series covered a wide variety of topics in the 20 years. However, it was discovered that there has been a notable move towards technically focused papers. Furthermore, topics such as business continuity had just about disappeared in the series while topics which are related to networking and cryptography continue to gain more prevalence.

- Description: Workflow systems have gained popularity not only as a research topic, but also as a key component of Enterprize Resource Planning packages and e- business. Comprehensive workflow products that automate intra- as well inter-organizational information flow are now available for commercial use. Standardization efforts have centered mostly around the interoperability of these systems, however a standard access control model have yet to be adopted. The research community has developed several models for access control to be included as part of workflow functionality. Commercial systems, however, are still implementing access control functionality in a proprietary manner. This dissertation investigates whether a comprehensive model for gain- ing context-sensitive access control, namely CoSAWoE, can be purposefully implemented in a commercial workflow product. Using methods such as an exploratory prototype, various aspects of the model was implemented to gain an understanding of the di±culties developers face when attempting to map the model to existing proprietary software. Oracle Workflow was chosen as an example of a commercial workflow product. An investigtion of the features of this product, together with the prototype, revealed the ability to affect access control in a similar manner to the model: by specifying access control constraints during administration and design, and then enforcing those constraints dynamically during run-time. However, only certain components within these two aspects of the model directly effected the commercial workflow product. It was argued that the first two requirements of context-sensitive access control, order of events and strict least privilege, addressed by the object design, role engineering and session control components of the model, can be simulated if such capabilities are not pertinently available as part of the product. As such, guidelines were provided for how this can be achieved in Oracle Workflow. However, most of the implementation effort focussed on the last requirement of context-sensitive access control, namely separation of duties. The CoSAWoE model proposes SoD administration steps that includes expressing various business rules through a set of conflicting entities which are maintained outside the scope of the workflow system. This component was implemented easily enough through tables which were created with a relational database. Evaluating these conflicts during run-time to control worklist generation proved more di±cult. First, a thorough understanding of the way in which workflow history is maintained was necessary. A re-usable function was developed to prune user lists according to user involvement in previous tasks in the workflow and the conflicts specified for those users and tasks. However, due to the lack of a central access control service, this re- usable function must be included in the appropriate places in the workflow process model. Furthermore, the dissertation utilized a practical example to develop a prototype. This prototype served a dual purpose: firstly, to aid the author's understanding of the features and principles involved, and secondly, to illustrate and explore the implementation of the model as described in the previous paragraphs. In conclusion the dissertation summarized the CoSAWoE model's compo- nents which were found to be product agnostic, directly or indirectly imple- mentable, or not implemented in the chosen workflow product. The lessons learnt and issues surrounding the implementation effort were also discussed before further research in terms of XML documents as data containers for the workfow process were suggested.
