CloudSEC: A Cloud Architecture for Composing Collaborative Security Services
Jia Xu, Yan Jia, Liang He, Purui Su, Dengguo Feng · 2010
Massive Internet invasions implemented through the distributed platform fabricated by rapid diffusion of malwares, has become a significant issue in network security. We argue that the notion of “Collaborative Security” is an emerging trend in resisting distributed attacks originated from malware. Therefore, this paper proposes a new architecture: CloudSEC, for composing collaborative security-related services in clouds, such as correlated intrusion analysis, anti-spam, anti-DDOS, automated malware detection and containment. CloudSEC is modeled as a dynamic peer-to-peer overlay hierarchy with three types of top-down architectural components. Based on, this architecture, both data distribution and task scheduling overlays can be simultaneously implemented in a loosely coupled fashion, which can efficiently retrieve data resources from heterogeneous network security facilities, and harness distributed collection of computational resources to process data-intensive tasks. Hence, CloudSEC endues the network security infrastructure with the capability of dynamic adaptation and collaboration on an inter-organizational scale. The results of preliminary evaluation demonstrate that, CloudSEC not only delivers a sample service of distributed intrusion correlation with high scalability and robustness, but also achieves remarkable effectiveness in data sharing and task scheduling.
