Dsse: distributed security shielded execution for communicable cyber threats analysis

Cloud computing is a new computing model which enables individuals and organizations to attain access to huge computing resources without capital investment. It does mean that users can utilize computing resources in pay per use fashion. Transmissible cyber threats nowadays have been considered one among the major serious security problems in cyberspace. Several techniques were proposed to model, simulate and identify threats' sources and their propagation in large-scale distributed networks. Most techniques are based on the analysis of real networks dataset that contains sensitive information. Traditional in-memory analysis of these dataset always leads to data leakage because of system vulnerabilities. If the dataset itself is compromised by adversaries, this threat cost would be even higher than the threat being analyzed. To overcome this problem, in this paper, a new Distributed Security Shielded Execution (DSSE) for communicable cyber threats analysis using the Secure Identity Based Encryption (SIBE) technique is proposed. The purpose of the proposed work is to provide security sensitive operations then implemented properly in the Disef enclave. And to minimize potential Iago attacks in Disef system. To introduce a Novel SIBE unbreakable new key-value encrypted format integrated with the version number and update counter to prevent possible rollback and replay attacks. Also to secure a Disef system in high availability with multi-cloud support. The experimental outcomes showed that the proposed framework supports secure cost analysis and response time analysis of large network dataset and has comparable performance with systems that have no confidentiality and integrity guarantees.
