Appropriate models for the analysis of security strategies at airports exist both macro and microscopically. None of these models allow for simulations across all modes of transport. OPAL is the most recent and promising of these approaches. It is based on a central database, which contains the necessary data for the data transfer between the different models integrated into OPAL. A standardization of the data in the simulation systems for assessing security concepts and the verification in an appropriate integration platform is still missing. A continuation of the OPAL approach for evaluating comprehensive security concepts “seat to seat” or for assessing the current to and to be expected security levels during operation has not been done yet.
