Blockchain has become a revolutionary technology that offers companies the possibility of transparency in transactions and the first cryptocurrency using this technology is Bitcoin. The blockchain is an immutable digital ledger of transactions that can be programmed to virtually record everything. The blockchain is a distributed database where information is shared across various computer networks. Blockchain has the ability to destroy more industries by making processes safe, transparent and efficient.
The blockchain provides a distributed transaction log that provides a secure way to map changes to decentralized networks. Each block of data will be present in the cryptographic document and will be printed on a specific network. The information on the network can only be read through the encryption process. Since each block of data would be marked with a date / time, the first block will represent the initial state of distribution and the last block will indicate the entire configuration. The advantage for blockchain on the network is that it can create complete information on the history of each device that is available on the network. This could improve efficient functions such as adapting firewall rules to check the current state by keeping a record even if a device is removed from the network.
The application of blockchain technology in management of the network life cycle checking and protecting records is a disadvantage. Efforts are needed to make the ledger work in a highly distributed and heterogeneous network. The process of creating blockchains to provide effective network services requires a lot of effort. Most organizations have a rigorous registration of configuration changes that led to the development of a reliable resource in the configuration management database (CMDB). CMDB is a database that contains all the information related to the hardware and software components used in IT organizations. Each component in CMDB is considered as a configuration element that can be software, hardware and a combination of components. The main tasks of configuration management include the identification of the configuration elements to be supported in CMDB, the modification of data only by authorized persons, the creation of a report on the current status and the accuracy of the data.
