    摘要： Provided is a DDoS attack detection apparatus including an information collecting unit to collect DDoS detection information including rate information about traffic change, variation of a first type flow and a Packet Per Second (PPS) for a second type flow, in which the rate information about traffic change is obtained using packet count of packets input per a unit time, flow count of flows input per the unit time and the byte count of bytes input per the unit time; and a testing unit to calculate a probability of occurrence of the DDoS attack by use of a first probability determined by the rate information about traffic change, a second probability determined by the variation of the first type flow and a third probability determined by the PPS for the second type flow and detect occurrence of the DDoS attack based on the probability of occurrence of the DDoS attack.

    摘要： A router having a black box function capable of storing a data block of a specific node or node group in a network, and a network system including the router are provided. The router includes: a black box memory storing node data; at least one packet preprocessor selecting and processing a data packet required to be stored in a black box from node data transferred via a wired/wireless transmission medium; a data storage storing the node data transferred through the packet preprocessor in the black box memory; a data reader reading corresponding node data in response to a node data transfer request from an external device; and a data transmitter processing the node data read by the data reader in the form of a packet and transferring the packet to the external device.
