Cloud networks are used to provide various services. As services are increasingly deployed using cloud networks, thereare a number of resources in the cloud that leverage a variety of environments and protocols. However, there is a securityintrusion on these resources, and research on cloud network vulnerability detection is required as threats to cloud resourcesemerge. In this paper, we propose a vulnerability detection scheme using STRIDE and HARM for vulnerability detection ofresources utilizing various environments and protocols, and present cloud network vulnerability detection scheme throughvulnerability detection scenario composition
