The present invention relates to a method for collecting data from a multi-domain in a data collection device. The method includes a step A of collecting data from a general web that is accessible through a search engine; a step B of collecting data from a dark web site that is not accessible with a general web browser and is accessible with preset specific software; and a step C of standardizing the collected data in a preset format and generating metadata for the collected data.

Method, device and computer program for collecting data from multi-domain

Provided are a terminal and method for storing and parsing log data. The method includes collecting log data on the basis of a file path of the log data, storing metadata including the file path and log data paired with the metadata in a database (DB), classifying the log data on the basis of the metadata, acquiring type information of a parser related to the log data, and parsing the log data through the parser having the type information.

Terminal and method for storing and parsing log data

A method for securing network communication between containers by a terminal, includes: a step of installing an HSI (Hyperion Secure Interface) for communication with a secure bridge included in an NIC (Network Interface Chip) in a secure container through a manager module; a step of changing a source address of a transmission packet to a specific token on the basis of a map of the HSI through the manager module; a step of delivering the transmission packet to the secure bridge through the HSI; a step of determining whether the specific token of the transmission packet is valid; and a step of changing the specific token to the source address and delivering the transmission packet to a target container when the specific token is valid.

Hardware-based reliable and secure container network

The present invention relates to a method for processing a knowledge graph in a data processing apparatus, comprising the steps of: (a) creating a knowledge graph including a taxonomy graph for a classification system of information objects and an entity graph for a relationship between specific information object instances; (b) updating the knowledge graph by reflecting the information objects extracted from a database in the knowledge graph; and (c) inferring the relevance of a random information object by using the updated knowledge graph.

Method, apparatus, and computer program for providing cyber security by using a knowledge graph

The present disclosure relates to a method for detecting a scam address of cryptocurrency using a machine learning model, and the method comprises: acquiring information about scam addresses labeled as being used for a scam transaction and information about benign addresses labeled as being used for a normal transaction from a database; acquiring information about a mule address group used for money laundering on the basis of the scam address group; acquiring feature information corresponding to each of the benign addresses and the addresses included in the scam address group or the mule address group on the basis of at least one of the information about the benign addresses, the information about the scam address group, and the information about the mule address group; and generating a machine learning model by machine learning of the feature information corresponding to each of the addresses and label information corresponding to each of the addresses.

Cryptocurrency transaction analysis method and apparatus

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides an apparatus and a method for handling a network attack in a software defined network (SDN). The method for handling a network attack in an SDN according to various embodiments of the present disclosure includes detecting a first candidate of the network attack in a flow during a first time interval, in response to detecting the first candidate, changing quality of service (QoS) of the flow from first QoS to second QoS, detecting a second candidate of the network attack in the flow of the second QoS during a second time interval following the first time interval, and in response to detecting the second candidate, blocking the flow. The apparatus and the method according to various embodiments of the present disclosure may gradually block a network attack through multiple levels, to thus reduce the probability of determining a wrong network attack and to lower a recovery cost for network failure. Therefore, the apparatus and the method according to various embodiments of the present disclosure enable efficient network management.
