  • Publication number: 20040049695
    Abstract: In a system for providing a real-time attacking connection traceback, an intrusion detection unit detects a hacker's attack. A packet block unit blocks a response of an attacked system. A path block tracing unit generates a policy to block a specific packet, collects a response packet, inserts the generated watermark in the packet, transmits the watermark-inserted packet to a system and forms a traceback path. A watermark detection unit checks a received/transmitted packet in a network, extracts a corresponding watermark if there exists the watermark-inserted packet and transmits the watermark-inserted packet detection information to an attacking connection traceback system that initially inserted a watermark into a packet.

  • Publication number: 20030159069
    Abstract: Disclosed is a network-based attack tracing system and method using a distributed attack detection agent and manager system that can detect and trace an attack path of a hacker in real time on the whole network using distributed network-based attack detection agent, request manager, and reply manager. The agent detects an attack using a network-based intrusion detection system (NIDS), analyzes an alarm log that is judged to be the attack, changes the analyzed alarm log into attack information, and transmits the attack information to the request manager. The request manager performs a search of an attack IP based on the attack information received from the agent, stores a result of search in a tree structure, and if a final search is completed, extracts a hacking path using a binary search tree (BST) algorithm.

  • Patent number: 5757589
    Abstract: A head device for use in a VCR comprises a head base with one end affixed to a rotary drum; a head chip that is installed at the other end of the head base and furnished with a vertical magnetic gap; and an actuator and a hinged leg for tilting the head chip up or down to thereby alter the azimuth angle of the magnetic gap. Such a head device makes it possible to manufacture rotary drums equipped with only one head. Since the azimuth angle of the magnetic gap is variable, such a head is capable of reading the signal recorded on a track of a magnetic tape, and by altering the azimuth inclination of its head chip, reading the signal on the adjacent track as well.
