A Study on Secure Cloud Analysis for National Infrastructure

The recently developed cloud is converging with other technologies and industries including AI and blockchain, and most online and offline services are composed of the cloud. It is widely used in major national and public institutions beyond the private sector. However, there are various security threats such as data leakage and loss when using data in a cloud environment. If sensitive information of users or important information is shared in the cloud, significant damage is expected when exposed to security threats. This paper is about technology trends and research for secure cloud architecture solutions for major national infrastructures. A survey on cloud policies in each major country and cloud policies being promoted in Korea will be explained. And based on the researched data, we suggest the direction, technology, and requirements to consider to securely configure the cloud to be used for major national infrastructure.
