What is Blockchain?

Blockchain is a shared, decentralized, and digital ledger that records transactions in the form of blocks. This ledger helps to store information transparently due to its property of immutability and access to allowed members only.

Possible Blockchain Use Cases For Cybersecurity

  • IOT Security:
    With the increasing application of AI and IoT, the security of data and systems from hackers has always been a major concern. Usage of Blockchain for improved security by using device-to-device encryption to secure communication, key management techniques, and authentication is a potential use case to maintain cybersecurity in the IoT system.
  • The integrity of software downloads:
    Blockchain can be utilized to verify updates and installers to prevent malicious software from infecting the devices. Here, hashes are recorded in the blockchain and new software identities can be compared to the hashes to verify the integrity of the downloads.
  • Data transmission protection:
    By using encryption, the data in transit will be protected from unauthorized access.
  • Decentralized storage of critical data:
    With the exponentially increasing data generated every day, blockchain-based storage solutions help achieve decentralized storage thus protecting digital information.
  • Mitigating DDoS Attacks:
    One of the most popular cyberattacks today is DDoS attacks where hackers aim to generate a flood of Internet traffic and thus disrupt the flow of services. The properties of immutability and cryptography help Blockchain prove to be an effective solution for these attacks.
  • DNS Security:
    The Domain Name System (DNS) is similar to a public directory that links domain names to their IP addresses. Over time, hackers have tried to access the DNS and exploit these links thus crashing sites. Due to Blockchain’s properties of immutability and decentralized systems, the DNS can be stored with enhanced security.
