    摘要： Disclosed are systems and methods for protection of a technological system (TS) from cyber attacks. An exemplary method comprises: obtaining a real state of the TS; initializing a cybernetic control system (CCS) by synchronizing the CCS with the TS; comparing, by the CCS, the real state of the TS with an ideal state of the TS; based on the comparison, identifying a deviation of the real state of the TS from the ideal state of the TS; when the deviation is identified, checking an integrity of at least functional interconnections of the states of one or more elements of the TS; determining whether the ideal state of the TS is a modeling error based on one or more confirmed sustained functional interconnections between elements of the TS; and identifying anomalies in the TS based on one or more disturbed functional interconnections between elements of the TS.

    摘要： Disclosed herein are systems and methods for detection of anomalies in a cyber-physical system in real-time. In one aspect, an exemplary method comprises: obtaining, in real-time, randomly distributed stream of observations of CPS parameters; converting an observation of the CPS parameter to a uniform temporal grid (UTG); when at least a criterion for unloading at least one UTG node of the converted observations is satisfied, unloading the UTG nodes corresponding to the satisfied criterion; for each unloaded UTG node, calculating a value of each output CPS parameter of a set of output CPS parameters; and detecting an anomaly in the CPS based on the values of the output CPS parameters.

    摘要： Disclosed herein are systems for identifying the structure of patterns and anomalies in flow of events from the cyber-physical system or information system. In one aspect, an exemplary method comprises, using at least one connector, getting event data, generating at least one episode consisting of a sequence of events, and transferring the generated episodes to an event processor; and using the event processor, process episodes using a neurosemantic network, wherein the processing includes recognizing events and patterns previously learned by the neurosemantic network, training the neurosemantic network, identifying a structure of patterns by mapping to the patterns of neurons on a hierarchy of layers of the neurosemantic network, attributing events and patterns corresponding to neurons of the neurosemantic network to an anomaly depending on a number of activations of the corresponding neuron, and storing the state of the neurosemantic network.
