We consider the first complete security analysis of GFS systems. We formalize desirable security properties with respect to the successful enforcement of access control mechanisms and data confidentiality by considering a threat model that is much stronger then in previous works. We propose extensions to the GFS protocols that satisfy these properties, and provide a comprehensive analysis of the extensions, both analytically and experimentally. In a proof-of-concept implementation, we demonstrate the practicality of the extensions by showing that they incur only a 12% slowdown while offering higher-assurance guarantees.
