An apparatus and method for generating a system call whitelist for an application container. The method may include determining whether a container is based on machine code or non-machine code by analyzing the internal configuration of the running container, identifying system calls included in an application through binary static analysis or static analysis of source code selected depending on the determination of whether the container is based on machine code or non-machine code, and generating a whitelist based on the numbers of all of the identified system calls.

A method and apparatus for providing security visibility into a container image. The method includes generating a software list by analyzing layers forming a container image, generating a vulnerability check result based on the software list, and generating a container image content report based on the software list and the vulnerability check result.

Method and apparatus for providing visibility of security into container images

An operation method of a system for generating a security profile of a security instance includes extracting executable code and a library file from a container, thereby identifying a target to be analyzed; performing binary static analysis for the executable code and the library file in order to generate a system call list; and generating a Secure Computing Mode (SECCOMP) security profile based on the system call list.

System and method for generating security profile of container instance

Disclosed herein are an apparatus and method for booting a virtual machine. The apparatus for booting a virtual machine includes: an access unit for accessing a virtual disk, corresponding to a virtual machine that exists in a virtualization area, using a trap generated by a trap generation unit, and for controlling the input and output of data stored in the virtual disk; an extraction unit for extracting data used for booting from the virtual disk; and a verification unit for extracting a trusted boot image from image storage and verifying the integrity of the data used for booting based on a result of comparing the trusted boot image with the data used for booting.
