In our increasingly connected world, maintaining the security of information systems is challenging. Today’s interconnected business environment calls for a change in how IS security is achieved to include thinking about the entire networks of relationships involved in preventing threats rather than just focusing on individual organizational security processes. Despite acknowledging the role of distributed and heterogeneous actors in achieving a secure environment, there is a lack of knowledge of how these actors actually prevent security threats. Moreover, the heterogeneity of actors involved gives rise to the issue of incentives needed to align their interests to ensure successful collective security efforts. This PhD thesis addresses these issues by zooming in on security networks, defined as collective efforts pursued by distributed actors to develop and adopt prevention measures to achieve security, to explain how these networks prevent security threats and identify the incentive mechanisms for converging the network’s heterogeneous actors. I challenge equilibrium and linearity assumptions identified in the current literature and argue for the need to adopt different theoretical and methodological approaches to uncover the dynamics in these networks. Through a historical case study of credit card fraud and how its prevention measures evolved over the last 55 years, I develop a process model of prevention encounters in security networks. The model depicts the dynamic and interactive nature of the prevention process and shows how the three proposed prevention mechanisms, namely, proposing solutions, resolving dissonance, and paving the way, interact to achieve prevention. The thesis further proposes three new forms of incentive mechanisms (transformative, preparatory, and captive) that are crucial for the survival of collective security efforts and show how they interact with the three prevention mechanisms. By this, this research complements the current security networks literature by offering a process model that explains how security networks achieve prevention. In addition, the interplay between the three incentive mechanisms reveals that incentives are not only ready-made structures or one-time event as depicted in the current literature but that they should also be seen as a socially dynamic process.
