Within the scope of this thesis, the question was
addressed under which conditions the use of cloud services, especially with the
use of the TLS protocol, is risk-based from a technical and user perspective.
The necessary prerequisites for a successful
man-in-the-middle attack on the TLS protocol were determined by theoretical
research on the topics of cloud computing, as well as safety-related aspects in
communication with this medium and a practical experiment. With these results,
an online survey was created. The answers were evaluated with cross-tabulation
tables. It turned out that the consulted people often ignores warnings and uses
unsafe connections.
From a technical point of view, faulty protocol implementations
and the key management used on the internet are subjects of risks. From the
user's point of view, the lack of knowledge about certificates and safety
mechanisms can be mentioned.
