Claim One:
1. A method of adapting a security configuration in a data processing application processed by a data processing device, wherein the adaptation is based on changes of assets associated with the security configuration and/or factors representative of the context of the data processing application, the method comprising the steps of storing a fuzzy causal network comprising a plurality of nodes and a plurality of incoming and outgoing causal links associated therewith, wherein at least application variables and security functions are assigned respective nodes, determining a current value of at least one application variable, determining a current security configuration as a set of security function nodes, updating the node corresponding to the at least one variable with the determined current value, propagating the updated value through the fuzzy causal network through at least one causal link associated with the updated node, processing the fuzzy causal network to determine a next security configuration consisting of an alternative set of security function nodes; and implementing the next security configuration by activating and/or deactivating corresponding security functions.
