In order to address security and privacy problems in practice, it is very important to have a solid elicitation of requirements, before trying to address the problem. In this thesis, specific challenges of the areas of social engineering, security management and privacy enhancing technologies are analyzed:
Social Engineering: An overview of existing tools usable for social engineering is provided and defenses against social engineering are analyzed. Serious games are proposed as a more pleasant way to raise employees’ awareness and to train them.
Security Management: Specific requirements for small and medium sized energy providers are analyzed and a set of tools to support them in assessing security risks and improving their security is proposed. Larger enterprises are supported by a method to collect security key performance indicators for different subsidiaries and with a risk assessment method for apps on mobile devices. Furthermore, a method to select a secure cloud provider – the currently most popular form of outsourcing – is provided.
Privacy Enhancing Technologies: Relevant factors for the users’ adoption of privacy enhancing technologies are identified and economic incentives and hindrances for companies are discussed. Privacy by design is applied to integrate privacy into the use cases e-commerce and internet of things.
After a recent spate of terrorist attacks in European and American cities, liberal democracies are reintroducing emergency securitarian measures (ESMs) that curtail rights and/or expand police powers. Political theorists who study ESMs are familiar with how such measures become instruments of discrimination and abuse, but the fundamental conflict ESMs pose for not just civil liberty but also democratic equality still remains insufficiently explored. Such phenomena are usually explained as a function of public panic or fear-mongering in times of crisis, but I show that the tension between security and equality is in fact much deeper and more general. It follows a different logic than the more familiar tension between security and liberty, and it concerns not just the rule of law in protecting liberty but also the role of law in integrating new or previously subjected groups into a democratic community. As liberal-democratic societies become increasingly diverse and multicultural in the present era of mass immigration and global interconnectedness, this tension between security and equality is likely to become more pronounced.
