Cloud computing is now on the verge of being embraced as a serious usage-model. However, while outsourcing services and workflows into the cloud provides indisputable benefits in terms of flexibility of costs and scalability, there is little advance in security (which can influence reliability), transparency and incident handling. The problem of applying the existing security tools in the cloud is twofold. These tools do not consider the specific attacks and challenges of cloud environments, e.g., cross-VM side-channel attacks. These tools focus on attacks and threats at only one layer of abstraction, e.g., the network, the service, or the workflow layers. Thus, the semantic gap between events and alerts at different layers is still an open issue.
