BioRAC: Biologically inspired resilient autonomic cloud

Our modern cyber-powered society will provide pervasive information services that will touch all aspects of our life and economy. However, we are experiencing grand challenges to secure and protect our cyberspace resources and services. The recent embrace of cloud computing due to their performance and cost considerations will further exacerbate the security problem. In cloud computing, organizations relinquish direct control of many security aspects to the service providers such as trust, privacy preservation, identity management, data and software isolation, and service availability. Traditional security techniques will not work well in a cloud environment due to many challenges related to the monoculture paradigm, the rapid and dynamic changes, the use of social networking software tools, and use of mobile devices. In this paper, we present the design of biorac: biologically-inspired resilient autonomic cloud that employs biologically inspired techniques and multi-level tunable redundancy techniques to increase attack and exploitation resilience in cloud computing. We briefly describe how biorac can tolerate and minimize the impact of novel cyber attacks.
