Classic intrusion detection mechanisms are not flexible enough to cope with cloud specific characteristics such as frequent infrastructure changes. This makes them unable to address new cloud specific security issues. In this paper we introduce the cloud incident detection system Security Audit as a Service (SAaaS). It is built upon intelligent autonomous agents, which are aware of underlying business driven intercommunication of cloud services. This enables the presented SAaaS architecture to be flexible and to supported cross customer event monitoring within a cloud infrastructure. A contribution of this paper it to provide a high-level design of the SAaaS architecture, an introduction into the proposed Security Business Flow Language (SBFL), a first prototype of an autonomous agent and an evaluation about, which cloud specific security problems are addressed by the presented architecture. It is shown that autonomous agents and behaviour analysis are fertile approaches to detect cloud specific security problems and can create a cloud audit system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
