INTRUSION DETECTION SYSTEM ON MULTI-CLOUD COMPUTING

Remote data checking is of crucial importance in Multicloud storage. It enables the users to their required data without downloading the whole data. The existing remote data possession integrity checking (ID-DPDP) protocols have been designed in the PKI (public key infrastructure) model. The multi-cloud server has to validate the users’ certificates before save the data uploaded by the clients in order to prevent attack. Distributed Denial of Service (DDOS) RTOL and normal attack are the major security issue that poses a great threat to the availability of the multi cloud services. We propose an intrusion detection system with ID-DPDP strategy that help identify the data leakage or attacks .Data Leakage is main problem in our Multicloud server, we can apply data leakage algorithm for data leakage detection and prevention from the intruder ,RSA algorithm for cryptography and Hashing index.
