A framework for intrusion tolerance in cloud computing

Abstract

Cloud Computing has been envisioned as the next generation architecture and one of the fastest growing segments of the IT enterprises. No matter how much investment is made in cloud intrusion detection and prevention, cloud infrastructure remains vulnerable to attacks. Intrusion Tolerance in Cloud Computing is a fault tolerant design approach to defend cloud infrastructure against malicious attacks. Thus to ensure dependability we present a framework by mapping available Malicious and Accidental Fault Tolerance for Internet Applications (MAFTIA) intrusion tolerance framework for dependencies such as availability, authenticity, reliability, integrity, maintainability and safety against new Cloud Computing environment. The proposed framework has been validated by integrating Intrusion Tolerance via Threshold Cryptography (ITTC) mechanism in the simulated cloud environment. Performance analysis of the proposed framework is also done. � 2011 Springer-Verlag.
