Efficient Solution for NoSQL Database Security in Blockchain - Based Applications

In recent years many applications have moved to blockchain-based services due to the increased popularity of blockchain technology. The implementation of this technology in numerous domain applications, such as finance, health management, land record registration, etc. As a result, data security and privacy are essential requirements of the Blockchain platform for protecting users' sensitive data and code. In this paper, a database security framework is proposed specifically tailored for Blockchain-based solutions, including projects based on Hyperledger. Furthermore, this framework detects vulnerabilities in MongoDB and CouchDB and suggests remedial actions. The solution identifies missing patches, exposed Config API, unauthorized changes, misconfigured privileges, and more.
