Abstract: A method of supporting decision-making of security control includes: (a) when an system for automatically analyzing a security threat receives a security warning from a security device, collecting security threat events generating the security warning from the security device; (b) when the collected security threat events exceed a preset event processing threshold, generating, by the system for automatically analyzing a security threat, a first request message for preferentially processing a security event; (c) when receiving the first request message generated from the system, determining, by the system for supporting priority of security control, a priority processing order of the security threat events, and notifying the system; and (d) when receiving the second request message generated from the system, determining, by the system for supporting priority of security control, a priority processing order and notifying the system for automatically analyzing a security threat of the determined priority process

Abstract: Disclosed are a system and method for automatically generating a playbook and verifying validity of a playbook based on artificial intelligence, wherein the system present invention includes a system for automatically generating a playbook that automatically generates the playbook, and a system for verifying validity of a playbook that is connected to the system for automatically generating a playbook through a network to perform the verification of the validity on the playbook received from the system for automatically generating a playbook.

Abstract: A device for automatically sorting a cyber attack includes an event feature generator that extracts a unique attacker IP by analyzing attacker IPs for each of the different kinds of security devices, and generates AI learning features of the security events of the different kinds of security devices including feature numerical data quantifying at least two or more features through attack information analysis recorded in the different kinds of security devices based on the information on the security events of the different kinds of security devices mapped to the extracted unique attacker IP, and an attack type sorter that learns the generated feature numerical data using an unsupervised learning algorithm, generates clustering data by sorting the feature numerical data into similar attack data and clustering sorted feature numerical data, and then analyzes the generated clustering data to identify a short-term or long-term attacker's cyber attack type.

Abstract: A tilt control method of a recording medium comprises fixing the recording medium to a recording reproducing apparatus; performing first tilt compensation in a state that the recording medium is stopped; and performing second tilt compensation in a state that the recording medium in which the first tilt compensation has been performed is rotated.

Abstract: There is provided an apparatus for recording/reproducing data on/from a recording medium including: a pickup unit including an objective lens and a solid immersion lens(SIL) to allow a light to be incident onto a recording medium; a photoelectric element for receiving the light reflected from the recording medium to output a controlling signal; and a controller to control the pickup unit using the controlling signal outputted from the photoelectric element, wherein the controlling signal includes a tilting error signal by skew of the recording medium.
