Abstract:
Cloud computing has many features such as low cost and ease of access to services, but
nevertheless has deficiencies related to security and privacy which must be taken into
account. Cloud computing represents a repository to store data, so data must be protected.
Protection of data by securing the environment surrounding the data results on loss of
control by the data owner, furthermore, the data move from one place to another and
from one environment to another, which means must secure these environments, as well
as to secure data as they move from place to another, and that there is the same
mechanism of protection in every environment the data move to it, this seems impossible
or difficult, which means that the protection through the surrounding environment of the
data is ineffective.
This research presents a model for securing data in the cloud computing by focusing on
the data itself rather than securing the surrounding environment. Protection by focusing
on data solve the loss of control problem in the cloud computing because the protection
mechanism would determined by the data owner, also the protection of data is achieved
at all stages of the data due to the protection mechanism is embedded with the data, this
model is based on a set of security requirements of cloud computing, which was derived
from a set of security risks of cloud computing that has a been derived from previous
studies, but the validity and consistency of the model has been left for future work due to
the scope of this thesis.
