Blockchain expansion is the high priority necessity to improve security. Hacking and other attacks are headway from system innovation and security measures for the cloud architecture. That is why the countermeasure deployed for such attacks should act in an opportune way and ought to be situated as close as possible to attacking device. As an example, DDoS attacks were not that complex as they are getting now with the new technology known as IoT. Imagine the consequences if 25 billion of IoT devices generate a huge amount of data for DDoS attacks. That is why we propose a new framework that can expand blockchain in a manner where more companies can share their resources to enhance security. So, we proposed a new and complete framework with cloud, fog, to secure configuration files with blockchain technology. Our framework considers the configuration files from SDN or NFV as an asset to secure with blockchain. By saving configuration files into blockchain, we can detect illegal changes occurred to configuration files after hacking attack. This study also focuses on expanding blockchain between the multiple service providers with ease to prevent waste of resources. This paper mainly provides opportunities for different could or companies to secure their assets by employing the power of blockchain and smart contracts.
