Cybersecurity is considered as one of the key challenges in today’s data-centric world. Modern technologies such as artificial intelligence (AI) and blockchain can help. With AI, companies can easily detect the pattern of the cybercrimes. In tandem with AI, blockchain has entered the cybersecurity scene with the promise of adding a layer of infallible security to the data.

Blockchain, also known as decentralized ledger, is a time-stamped recorder where data is stored in a block. Each data transfer in a blockchain is stored in a separate block and each block is connected with a chain-like configuration. All these blocks are encrypted with a cryptographic key, thereby thwarting cyberattacks. Moreover, as blockchain is a decentralized ledger, the content stored in the blockchain can never be modified without the user authorization. Even if it is modified by the user itself, it tracks all the changes up-to-date and this is a constant process.

Whenever an organization participates in a blockchain, an SSL certificate is issued for every device in the organization, instead of a password. In addition, blockchain holds full authority on the management of these certificates; therefore it is impossible for hackers to penetrate through blockchain. The blockchain technology can be used in both public and private applications.
