Blockchain technology has received much attention for its digital storage and security applications. Blockchain technology has many benefits regarding network security, including decentralization, immutability and transparency, which can significantly increase the level of protection for networks. Decentralization is one of the key advantages that blockchain can bring to network security. Conventional network security systems have control of data, which is all centralized in front of a single entity, making them easily attacked. On the other hand, blockchain technology decentralizes data control and therefore, the distribution of potential hacking in nodes makes it almost impossible to hack or breach the entire network. Specifically, the blockchain is immutable; its construction protects against any data modification occurring on the network when no vote by a majority of nodes permits a change. It renders cybercriminals nearly incapable of modifying the network data, which adds an extra layer of protection. Transparency is another key feature of blockchain technology since all participants in the network will have access to view any transaction conducted on the network. This functionality helps monitor any unauthorized or suspicious activity on the network, providing a chance to be vigilant and address the issue.
