    Abstract: An apparatus and method for assessing cybersecurity vulnerabilities based on a serial port. The apparatus includes a vulnerability DB for storing vulnerability assessment items, a communication unit for configuring an environment for serial communication with an assessment target device and configuring a network environment, a vulnerability scanning unit for selecting a vulnerability assessment item for which cybersecurity vulnerability assessment is to be performed on the assessment target device, and performing scanning for checking the selected vulnerability assessment item on the assessment target device, a response analysis unit for analyzing a response of the assessment target device to the scanning, and setting one or more of an operating system, an application, and a protocol corresponding to the assessment target device, and a vulnerability presence determination unit for determining, using the set one or more of the operating system, application, and protocol, whether a vulnerability is present.

    Abstract: Disclosed are an apparatus and method for reconstructing a transmitted file with high performance in real time, which select analysis target packets for reconstruction by first checking using hardware whether data file-related information is present in packets transmitted via large-capacity traffic over a broadband network, and which reconstruct a file in real time only from the selected analysis target packets. The file reconstruction apparatus for reconstructing a data file from packets on a network includes a packet monitoring unit for extracting packets on the network, a collected packet selection unit for determining whether, for the extracted packets, each packet is a reconstruction target based on flow information, and selecting a reconstruction target packet, and a file reconstruction unit for performing file reconstruction by extracting data from the reconstruction target packet and by storing the extracted data as data of a reconstructed file in a relevant flow.
