Revealing the Weaknesses of File Sharing System on Cloud Storages
This addresses security risks for users of specific cloud storage services, but is incremental as it focuses on known vulnerabilities in a limited set of providers.
The paper analyzed security vulnerabilities in file sharing systems of three Chinese cloud storage providers (Baidu, Weiyun, Kanbox) and provided countermeasure suggestions to improve security while maintaining quality.
Cloud storage provides the simpler way to share the files privately and publicly. A good Cloud Storage Provider (SCP) is not only measured by the access speed or file size that can be shared to others, but also regarding the security issues in file sharing itself. In this paper, we analyze the security of file sharing in 3 Chinese CSPs, which are: Baidu, Weiyun and Kanbox. Those CSPs have their own vulnerabilities that successfully revealed. We also provide some suggestions to countermeasure the weaknesses so that they can maintain the quality while improving the security.
