A Hybrid Security Framework to Preserve Multilevel Security on Public Cloud Networks

Cloud computing uses the “pay as you go model” to provide on-demand services to its users, especially data storage, computing power, network, and others. In recent years, Cloud Technology, a decentralized network has become one of the optimal solutions to store and process large amounts of data. Cloud Networks store and process data by achieving security in terms of authentication, integrity and privacy, a great challenge in today’s world. This paper had proposed a Multilevel level hybrid security framework to preserve security with the use of session key generation, cryptography algorithms, chain of hashes, and storing data with the use of decentralized approaches such as BlockChain. This framework preserves all the security services and mitigates the number of passive and active attacks such as modification, fabrication, session hijacking, network jamming, DOS attack, and attempts to modify or manipulate paths for gaining access.
