  1. Cloud systems are integral for delivering scalable and virtualized resources globally. It also provides security updates and monitoring to keep user data safe. However, the growing complexity of these systems poses significant challenges, particularly in the realm of logging and security. It is difficult to know for users which detail is critical for further security analysis of the resources. Also, external packages used in the cloud system require updates by users to mitigate the vulnerability, but the large number of packages to manage makes them outdated versions. This paper shares the weakness of cloud logging systems we observed, which can be exploited by attackers. We propose a tool that configures alerts automatically when commands that have missing details in logs are executed and updates vulnerable versions of packages. Our tool leverages a list that includes the commands with missing details in logs and packages that need to be updated because of the known vulnerabilities. To make the list, we conduct complete enumerating for 1,279 commands in five major resources of Azure to find logs with missing details and search related communities to find vulnerable packages that require the manual update. We evaluate the proposed tool with eight attack scenarios based on real-world cases and the result shows that our tool prevents them successfully.
