—Enforcing a behavioral pattern in any system will force it to behave in the expected way thorough which it can be secured against any unauthorized access leading to a trusted environment. Security assurance in cloud computing environment is a major challenge associated with lack of trust and vulnerability to unauthenticated access that requires the providers to secure virtualized data centers by preserving data integrity. To improve the customer’s confidence on cloud, trust has to be restored by developing trusted computing model for various cloud services ranging from storage, network, and infrastructure to everything as a service. Current trends suggest that the digital world is going to be more and more flexible, interconnected and open to public access and hence the trust associated with it has to be managed based on variety of key security techniques like identity management, digital signatures, credential exchange, certificates and key management. Nevertheless attacks on public as well as private data’s in cloud ecosystem exposes the inherent failure in protection mechanism. This paper proposes an attestation server that defines the functionality and measures the behavioral pattern of hypervisor, BIOS, boot devices and other operating system modules to verify it with good/known databases to determine nodes trustworthiness. Also provides an understanding of various attestation models and standards that justify that attestation as a service is a trustworthy mechanism to enable an ordinary platform to behave as a trusted computing platform.
