FIELD: physics; computer facilities.
SUBSTANCE: invention concerns systems of safety of information networks. The system contains block of traffic filtering, the block of calculation of autocorrelative function, the block of calculation of coefficients of autoregression, the block of the filter of autoregression, keys, the block of keys management, the block of calculation of a coefficient of correlation, the decision box, thus these blocks allow to calculate parametres of real and standard profiles of behaviour of a source of load, to estimate a degree of a linear dependence of these profiles and to make of solution on attack presence.
EFFECT: detection of attacks in information networks, detection of attacks in information networks, and also detection of atypical behaviour of a loading source which can consist in a non-standard operating mode, change of network activity.
