In this week my reading was (Hussain, 2017)in which the author described that a multilevel classification model presents to identify the attack types and risk levels at each cloud layer. They classify the risks as low, medium, and high based on the cloud layer type. Their findings conclude that the risk level depends on the position of could layer and infrastructure layer affected mostly by attacks. Furthermore, the severe attacks depend on data encryption technique, multi-tenancy and authentication mechanism.
