1. System for retroactive, dynamic determination and/or monitoring of collateralization levels of technical installations ( 201 , 211 , 221 ), it being possible to aggregate and analyse measured data and to activate operation-specific system means ( 14 ), characterized in that in each case a configuration ( 30 ) based on acquired data specific to the mode of operation can be dynamically determined by means of a filter unit ( 12 ) for different modes of operation and can be stored with assignment to the corresponding mode of operation via a lookup table, the filter unit ( 12 ) comprising a network interface for access to network nodes connected to source databases ( 40 , 41 ) via a network ( 50 ) for acquiring data specific to the mode of operation, in that the system comprises a statistical analysis module ( 10 ) having an interface for aggregation and analysis of operation-specific measured data ( 31 ) via the network ( 50 ), which measured data ( 31 ) can be assigned by means of the lookup table to at least one specific parameter ( 30 ), it being possible to determine corresponding collateralization levels ( 32 ) by means of the analysis module ( 10 ) on the basis of the cumulative operation-specific measured data ( 31 ), in that the system comprises a monitoring unit ( 14 ) having an interface, it being possible for the corresponding collateralization level ( 32 ) to be dynamically adapted on the basis of a request and/or a determinable time interval by means of the monitoring unit ( 14 ) and/or, on exceeding a definable deviation value relative to already stored measured data, for operation-specific system means ( 202 , 212 , 222 ) to be activated.
