Abstract: Disclosed herein are a network environment synchronization apparatus and method. The network environment synchronization apparatus includes one or more processors, and execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to collect data from a network environment and generate a management structure in which collected data is distributed into preset respective group units, generate data discriminators for respective group units using a preset hash function, determine whether data of the management structure has changed with reference to data newly collected from the network environment based on the data discriminators, and when it is determined whether data of the management structure has changed, update the data of the management structure with the newly collected data.

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 herein is an apparatus for enhancing network security, which includes an information collection unit for collecting information about states of hosts that form a network and information about connectivity in the network; an attack surface analysis unit for analyzing attack surfaces by creating an attack graph using the information about the states and the information about connectivity; a security-enhancing strategy establishment unit for establishing a security-enhancing strategy based on the attack graph; and a security-enhancing strategy implementation unit for delivering a measure based on the security-enhancing strategy to a corresponding host, thereby taking a security-enhancing measure.
