Abstract: Disclosed herein are an artificial Intelligence (AI)-based cyber training method. The AI-based cyber training method may include generating a unit attack by training an attack agent based on environment and state information of a cyber range (CR) and a set of attack tools executable on a system, executing the unit attack in the CR, and then determining whether the unit attack has succeeded, and determining whether to perform an attack or a defense based on whether the unit attack has succeeded.

Abstract: Disclosed herein is a device equipped with flash memory, which includes memory in which at least one program is recorded and a processor for executing the program. The memory includes flash memory including a data area and a backup area, and the program divides data into two or more segments depending on whether the data can be stored in a single page and stores the same in the data area. The first segment is stored in a page along with a segment number, indicating the sequential position of the divided data, a segment offset, indicating the number of pages between the pages in which the current segment and the next segment are stored, the size of a data file name, the size of the data, and the file name. At least one additional segment may be stored in another page along with the segment number and segment offset thereof.

Abstract: Disclosed herein is a method of operating a data management apparatus. The method may include segmenting, by a client device, data into multiple data blocks, generating, by the client device, tags corresponding to the multiple data blocks, generating, by the client device, a representative value by accumulating the tags, generating, by the client device, a client signature value by signing the representative value and a counter value corresponding to the last updated data block, among the multiple data blocks, and transmitting, by the client device, the data and the client signature value to a server.

Abstract: Disclosed herein are a decoy apparatus and a method for expanding a fake attack surface using a deception network. The method includes determining, by a protected server, whether a packet is a target to be processed when the packet is received; converting, by the protected server, the packet and transmitting, by the protected server, the converted packet to the decoy apparatus of the deception network when the packet is determined not to be such a target; receiving, by the protected server, a response packet from a decoy virtual machine included in the decoy apparatus as a reply to the converted packet; and modifying, by the protected server, the response packet and transmitting, by the protected server, the modified response packet to the source from which the packet was transmitted, in order to expand the fake attack surface.

Abstract: Disclosed herein are a server apparatus, a client apparatus, and a method for communication based on network address mutation. The method for communication based on network address mutation, performed by the server apparatus and the client apparatus, includes setting the external address of a network interface for receiving a packet from the client apparatus; setting the internal address of a hidden interface in order to forward the packet received through the network interface to the hidden interface; modifying the external address based on a preset network address mutation rule; and communicating with the client apparatus by forwarding the packet, received from the client apparatus based on the modified external address, to the hidden interface.

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.
