Abstract: The present invention relates to a smart terminal fuzzing apparatus and method using a multi-node structure. The smart terminal fuzzing apparatus includes a fuzzing command management unit for managing fuzzing instructions corresponding to performance of fuzzing. An algorithm management unit creates fuzzing commands based on the fuzzing instructions, and distributes the fuzzing commands to a plurality of fuzzing nodes connected to a fuzzing client depending on a distribution algorithm. A fuzzing client management unit performs control such that fuzzing is performed by the plurality of fuzzing nodes in compliance with the fuzzing commands through the fuzzing client. A log management unit receives results of performance of fuzzing from the plurality of fuzzing nodes and manages the fuzzing results.

Abstract: A packet analysis apparatus and method and a VPN server, which secure evidence against a situation in which a hacker disguises a packet as a normal packet to make an attack using a VPN server as a router. The packet analysis apparatus includes a packet classification unit for gathering and classifying packets which are used between a host and the VPN server and plaintext packets which are used between the VPN server and a target. A first comparative analysis unit compares contents of an encapsulated IP datagram of each encrypted VPN packet, obtained by decrypting the encrypted VPN packet, with contents of a plaintext IP datagram included in each plaintext packet and present for a target to which the host desires to transfer the encrypted VPN packet. A second comparative analysis unit compares lengths of the encapsulated IP datagram and the plaintext IP datagram with each other.

Abstract: An apparatus and method for processing packets are disclosed. The apparatus for processing packets includes a session processing unit, a parallel processing unit, and a storage unit. The session processing unit divides a packet group, including a plurality of HTTP packets, into a plurality of session files, and then distributes the session files. The parallel processing unit generates metadata and extracts content from each of the distributed session files based on the plurality of session files. The storage unit stores the metadata generated by the parallel processing unit and the content extracted by the parallel processing unit.

Abstract: An intrusion detection apparatus and method using a load balancer responsive to traffic conditions between a central processing unit (CPU) and a graphics processing unit (GPU) are provided. The intrusion detection apparatus includes a packet acquisition unit, a character string check task allocation unit, a CPU character string check unit, and a GPU character string check unit. The packet acquisition unit receives packets, and stores the packets in a single task queue. The character string check task allocation unit determines the number of packets in the packet acquisition unit, and allocates character string check tasks to the CPU or the GPU. The CPU character string check unit compares the character strings of the packets with a character string defined in at least one detection rule inside the CPU. The GPU character string check unit compares the character strings of the packets with the character string inside the GPU.
