Definitely a hard topic to understand, to study, to
analyze and specially to protect, as it brakes with territorial
limits in the world and almost of time, due to the immediate access
to the information or services through the "cloud" from
different places of the earth and which information is curiously
not in the clouds, but in an unknown and probably different
territory from the one in which the service is being
used.
However, the Cloud Computing is not
actually a subject of protection really, instead, we protect the
information, data (personal, financial, sensitive, etc.) and the
rights that each of said data contains.
That is, Cloud Computing, must have as
basis: security and privacy, either to the users or to the
information or contents treated and/or stored through this services
in the cloud, which should be mentioned that are legally known as
Software as a Service (SaaS).
