METHOD FOR PROTECTING INFORMATION AND TELECOMMUNICATION NETWORK FROM PASSIVE COMPUTER ATTACKS Russian patent published in 2018 - IPC G06F21/55 H04L12/70 

FIELD: information technology.

SUBSTANCE: probability of attacker's awareness of the protected information and telecommunication network (ITN) is calculated for a given time interval, taking into account the type and number of detected passive computer attacks, the value of the calculated probability of the attacker's awareness for a given time interval is compared with a predetermined threshold value; if the calculated value of the attacker's awareness does not exceed the predetermined threshold, a plurality of control actions on the ITN and its protection system are selected in accordance with the calculated probability of the attacker's awareness, and the selected control actions are applied to the ITN and its protection system; the reception and transmission of message packets (PS) to the communication channel is prohibited when the calculated probability of the attacker's awareness of the protected ITN exceeds the given threshold value, as well as when the impact of an active computer attack is determined.

EFFECT: increased coefficient of effective operation of information and telecommunication network, taking into account the level of attacker's awareness of the protected information and telecommunication network.
