A Web-Based Monitoring System of Network Security Functions in Blockchain-Based Cloud Security Systems

To prevent security attacks targeting enterprises and services, security managers use Network Security Functions (NSFs) from various manufacturers. For the unified management of these used NSFs, the Interface to Network Security Functions (I2NSF) Working Group of Internet Engineering Task Force (IETF) provides a framework with standard interfaces and data models to easily configure the NSFs. The user can use this framework to easily manipulate and manage NSFs configuration without any security expertise. One of the proposed interfaces is the Monitoring Interface that can be used to monitor the performance and status of the NSFs. We implemented a blockchain network using Hyperledger Fabric to ensure the integrity of the monitoring data of the NSFs delivered through the monitoring interface. In addition, we implemented a web application that can visualize the monitoring data of NSFs in realtime by implementing REST API using the JavaScript-based Hyperledger SDK.
