| Résumé |
Cloud-based storage services such as Dropbox, Google Drive and
OneDrive are increasingly popular for storing enterprise data, and
they have already become the de facto choice for cloud-based backup
of hundreds of millions of regular users. Drawn by the wide range of
services they provide, no upfront costs and 24/7 availability across
all personal devices, customers are well-aware of the benefits that
these solutions can bring. However, most users tend to forget-or
worse ignore-some of the main drawbacks of such cloud-based
services, namely in terms of privacy. Data entrusted to these
providers can be leaked by hackers, disclosed upon request from a
governmental agency's subpoena, or even accessed directly by the
storage providers (e.g., for commercial benefits). While there
exist solutions to prevent or alleviate these problems, they
typically require direct intervention from the clients, like
encrypting their data before storing it, and reduce the benefits
provided such as easily sharing data between users. This practical
experience report studies a wide range of security mechanisms that
can be used atop standard cloud-based storage services. We present
the details of our evaluation testbed and discuss the design
choices that have driven its implementation. We evaluate several
state-of-the-art techniques with varying security guarantees
responding to user-assigned security and privacy criteria. Our
results reveal the various trade-offs of the different techniques
by means of representative workloads on top of industry-grade
storage services. |
