Project Description


There are many possibilities to reach an intended security objective and companies, public authorities, institutions or, in general, persons have to decide for one of these alternatives. In theory, an optimal security measure should be safe and secure, trustworthy, efficient, and should not violate rights, but most of the time the chosen strategy is unbalanced.

This imbalance is why the project aims to provide a contribution to the modernization of the security architecture in Germany. It raises up the system of incentives for innovative security actions by a comprehensive, participative, cross-sectional, interdisciplinary and cross-sectoral observation. This happens in consideration of the specific regional and sectoral economic structures, as well as of legal and societal implications. The result will be a software tool able to support security actors by the assessment of economic, social and legal questions during the decision-making and planning process of security actions.


To accomplish those objectives, it is necessary to include every aspect and dimension which is helpful for the assessment of security actions. Therefore, five case studies will be analysed by principles and rules on the basis of a formerly developed innovative economic-society model of security. This model is oriented towards the expectations of security actors along the dimensions of security, trust, efficiency and law. Because of this focus, it is possible to connect the economic and legal perspective with a practical point of view. Conflict zones and critical information for the decision-making and planning process will be carved out and prioritised by a “deep learning proceeding” which builds a hierarchy of relevance. As a result, a software tool will be capable of bringing up and rating the direct, indirect and immaterial costs of different security actions with regard to their benefit.
