    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: 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.
