Many of these challenges relate to the lack of organizational understanding pertaining to the Shared. Responsibility model prevalent in the IT Cloud. The model states that the vendor is responsible for creating a. service, and the. client is. responsible for using the service in a. secure manner. This is mainly due to a. false sense of belief that. Cloud vendors handle security end-to-end. This creates a new security paradigm which gives employees. privileges that in the past could only be performed by. IT personnel having the authority with on-premise systems.”]
