Second Line of Defense for Cybersecurity: Blockchain

Abstract

AI as the first line of defense for cybersecurity, the goal was to keep the cyber-criminals at bay, but in case they managed to get in and infiltrate the network, we need to initiate the second line of defense – blockchain. New blockchain platforms are stepping up to address security concerns in the face of recent breaches. Transactions in the blockchain can be audited and traced. Since a blockchain system is protected with the help of ledgers and cryptographic keys, attacking and manipulating it becomes extremely difficult. Blockchain decentralizes the systems by distributing ledger data on several systems rather than storing them on one single network. The confidentiality of network members is high due to the public-key cryptography that authenticates users and encrypts their transactions. The distributed ledger ensures the protection of data against modification or destruction.
