1. A computer system configured to communicate with an industrial system, the computer system comprising:
a data collection server configured to receive equipment data from the industrial system and to provide a data stream by pre-processing the equipment data according to a plurality of pre-determined rules;
a first uni-directional interface configured to transmit the data stream to one or more further computer systems; and
a second uni-directional interface configured to receive a data packet from the one or more further computer systems, the data packet comprising a control instruction that allows a modification of at least one particular rule of the plurality of the pre-determined rules,
wherein the first uni-directional interface comprises a data diode,
wherein the second uni-directional interface comprises at least one sensor configured to receive the data packet from a mobile data carrier in proximity of the at least one sensor over an air-gap, the mobile data carrier being communicatively coupled to the one or more further computer systems,
wherein the second uni-directional interface is configured to receive the control instruction in a first part of the data packet,
wherein the second uni-directional interface is configured to receive the first part of the data packet in a size limitation that corresponds to amounts of data required to identify the modification of the particular rule,
wherein the size limitation of the first part has an equivalent limitation by the second uni-directional interface that is configured to receive the first part in a maximum size, and
wherein the maximum size depends on a number of rule modifications in the control instruction.
