Cloud computing : security challenges
Although cloud computing can help companies
accomplish more by breaking the physical bonds between an IT
infrastructure and its users, heightened security threats must be
overcome in order to benet fully from this new computing
paradigm that offers an innovative business model for
organizations to adopt IT without upfront investment. Despite
the potential gains achieved from the cloud computing, the model
security is still questionable which impacts the cloud model
adoption. The security problem becomes more complicated under
the cloud model as new dimensions have entered into the problem
scope related to the model architecture, multi-tenancy, elasticity,
and layers dependency stack. In this paper we introduce a
detailed analysis of the cloud security problem. We investigated
the problem from the cloud architecture perspective, the cloud
offered characteristics perspective, the cloud stakeholders'
perspective, and the cloud service delivery models perspective.
Based on this analysis we derive a detailed specication of the
cloud security problem and key features that should be covered
by any proposed security solution.
