Abstract: In a cybersecurity assessment method for ship assets, a risk level of each asset on a ship is automatically evaluated using asset-related information as input, and for an asset whose risk level exceeds a preset threshold, a security-control configuration set is generated and output. Accordingly, even when assets on the ship or network configurations change, a risk state can be rapidly re-evaluated and necessary security measures can be consistently derived.

Abstract: A virtual machine provisioning method according to an embodiment includes a provisioning module that creates a virtual machine image template including only an operating system image and a system file image, a virtual machine management module that extracts the OS image of the virtual machine image template according to a virtual machine creation command from a user, to load the OS image into a memory allocated a virtual machine, and execute the OS image, and an interface module that extracts a system file image of the virtual machine image template according to the virtual machine creation command to build a root file system for the virtual machine.
