Structure of the knowledge base

The Securipedia wiki is structured around a number of concepts which are essential to an urban planners in order to include security consideration in his urban planning process. These concepts are graphically depicted in the figure below.

Central in the knowledge base is the object that the urban planner is developing. This object can be a single building or infrastructure, but might also entail the renovation of a complete quarter of a city. This object has to provide in certain functions, such as mobility functions for a new bridge, economic functions for a mall, social functions for a stadium or safety functions such as protection for the elements or privacy for almost all types of buildings. These functions can both be distinguished for the object itself, and for its surroundings. These functions interact: the mobility function of a bridge can contribute to the economic function of the city. As these interactions are important to keep in mind when looking atthe security aspects of urban planning, these functions are categorized and described in this knowledge base.

The urban object is designed to fulfil these functions according to the requirements. However, the fulfilling of these requirements can be frustrated by the actions of persons who seek to do harm (threats). This is why the knowledge base will also provide information about the various types of threats, their motivation (motives) and the means they have to their disposal to succeed in their intentions.

The only means at the disposal of the urban planner to mitigate the threats, is to take mitigative measures. These are provisions taken to lessen the chance of succes or impact of an attack. In order to know which measures might be effective against what threats, the knowledge base will contain information about measures.

The urban planner does not have unlimited liberty in the measures he is allowed to take. These are subject to legal and ethical restrictions that enforce additional requirements to the measures that are feasible. This is why in this knowledge base, also information about the legal an ethical requirements is included.
