FIELD: radio engineering, communication.SUBSTANCE: invention relates to radio engineering and is intended to prevent leakage and erasure of information in data telecommunication systems. The invention involves comparing analysed unauthorised actions with given classes of unauthorised actions, detecting new classes of unauthorised actions and taking then into account during further classification of unauthorised actions. To this end, the invention includes a device for inputting the initial number of classes, an adder, a code converter, switch units and a comparator unit. The output of the unauthorised action classifier is connected to the combined first inputs of comparators of the comparator unit, with the first input of the database of classes of unauthorised actions. Through the output of the device for detecting unauthorised actions on a data telecommunication system, second inputs of the j-th comparator of the comparator unit are connected to corresponding outputs of switches of the second switch unit; the output of the j-th comparator of the comparator unit is connected to the j-th input of the logic NOR element, the output of which is connected to the second input of the switch; the output of the switch is connected to the second input of the database of classes of unauthorised actions; the first inputs of the switches of the second switch unit are connected to corresponding outputs of the database of classes of unauthorised actions.EFFECT: wider classes of detected unauthorised actions.2 dwg |
