    摘要: The present invention relates to a file detecting system and a method thereof. The file detecting system uses a signature of a file header and collects a network packet including a file to be detected among packets transmitted/received through a network. Subsequently, after the network protocol header is eliminated from the collected network packet, the file is reassembled and recovered. The recovered file is verified, and the verified file is transmitted to various file analysis systems.

    摘要: Provided is an attack classification method for computer network security. In the attack classification method, attacks are classified depending on vulnerability abused by an attack, attack propagation skills, and attack intentions. The classification results are arranged in the order of the vulnerability abused by an attack, the attack propagation skills, and the attack intentions. The arranged classification results are output. Accordingly, it is possible to easily detect an attack flow where an attack A propagates in the propagation skill C using the vulnerability B and the attack skill F is used for the attack target E to achieve the attack purpose D.

    摘要: A method and apparatus for protecting an application layer in a computer network system. The method includes creating a session between a client and a data provider in response to a session connection request from the client, and determining the client as an application layer attacking client when the client generates a session termination request before the data provider transmits to the client a response packet to a data request from the client under the created session.

    摘要: There are provided a network attack detection apparatus and method capable of determining even unknown network attack, the apparatus connected between two networks or connected by port mirroring of an Ethernet switch to real-time monitor all packets flowing through the networks. The apparatus decodes a payload portion of an inputted network packet into a machine code instruction, determines whether an executable code is included in the decoded machine code by analyzing relationship between instructions, and determines whether the packet is harmful based on statistics with respect to a possibility that an executable code exists in a service and a certain transaction of the service when the executable code is included.

    摘要: The present invention relates to an apparatus and method for detecting malware. The malware detection apparatus and method of the present invention determines whether a file is malware or not by analyzing the header of an executable file. Since the malware detection apparatus and method can quickly detect presence of malware, it can shorten detection time considerably. The malware detection apparatus and method can also detect even unknown malware as well as known malware to thereby estimate and determine presence of malware. Therefore, it is possible to cope with malware in advance, protect a system with a program, and increase security level remarkably.
