Abstract: A method, an apparatus, and a system for analyzing traffic through obtaining flow data of a flow from a switch or a router of a network, calculating an average byte per packet rate (BPR) and a TCP flag ratio (TCPFR) for all flows included in a session including the flow using the flow data, and comparing the average BPR and the TCPFR with an average BPR and a TCPFR of previously-known traffic and determining whether the traffic including the flow is normal traffic or abnormal traffic based on the comparison result are provided.

Abstract: A method for visualizing record data with a mobile forensic device for collecting and managing the record data including partner information when an event, such as a call or text service, occurs, includes: calculating an event occurrence frequency for each partner information using the collected record data; and classifying the partner information on the basis of a grade according to the calculated event occurrence frequency. Further, the method includes generating graphic data showing a relation between the partner information and user information of a mobile terminal on the basis of the classified grade; and displaying the graphic data.

Abstract: A method and a computation apparatus detecting cyber threats using a neural network through steps of: generating a learning model by performing machine learning on training data based on baseline data, converting a security event collected in real time into input data for the neural network, and determining, as an output corresponding to the input data based on the learning model, whether the security event is normal or threat are provided.
