Nowadays information is everywhere. Organisations process, store and create information in unprecedented quantities to support their business processes. Similarly, people use, share and synthesise information to accomplish their daily tasks. Indeed, information and information technology are the core of business activities, and a part of daily life. Information has become a crucial resource in today‘s information age and any corruption, destruction or leakage of information can have a serious negative impact on an organisation. Thus, information should be kept safe. This requires the successful implementation of information security, which ensures that information assets are only used, modified and accessed by authorised people. Information security faces many challenges; and organisations still have not successfully addressed them. One of the main challenges is the human element. Information security depends to a large extent on people and their ability to follow and apply sound security practices. Unfortunately, people are often not very security-conscious in their behaviour; and this is the cause of many security breaches. There are a variety of reasons for this such as a lack of knowledge and a negative attitude to security. Many organisations are aware of this; and they attempt to remedy the situation by means of information security awareness programs. These programs aim to educate, train and increase the security awareness of individuals. However, information security awareness programs are not always successful. They are not a once-off remedy that can quickly cure information security. The programs need to be implemented effectively, and they require an ongoing effort. Unfortunately, this is where many organisations fail. Furthermore, changing individuals‘ security behaviour is difficult due to the complexity of factors that influence everyday behaviour. In view of the above, this research project proposes an alternative approach in the form of a personal information security agent. The goal of this agent is to influence individuals to adopt more secure behaviour. There are a variety of factors that need to be considered, in order to achieve this goal, and to positively influence security behaviour. Consequently, this research establishes criteria and principles for such an agent, based on the theory and practice. From a theoretical point of view, a variety of factors that influence human behaviour such as self-efficacy and normative beliefs were investigated. Furthermore, the field of persuasive technology has provided for strategies that can be used by technology to influence individuals. On the practical side, a prototype of a personal information security agent was created and evaluated through a technical software review process. The evaluation of the prototype showed that the theoretical criteria have merit but their effectiveness is largely dependent on how they are implemented. The criteria were thus revised, based on the practical findings. The findings also suggest that a personal information security agent, based on the criteria, may be able to positively influence individuals to be more secure in their behaviour. The insights gained by the research are presented in the form of a framework that makes both theoretical and practical recommendations for developing a personal information security agent. One may, consequently, conclude that the purpose of this research is to provide a foundation for the development of a personal information security agent to positively influence computer users to be more security-conscious in their behavior.
