Cyber Chain – Merging Blockchain with Cyber Security

Abstract

The new digital economy is plagued by profound flaws because it relies on centralised systems
with a single control point that are attractive and easy targets for cyber attackers. This study
examines how Blockchain Technology can remedy these inherent security vulnerabilities.
Blockchain is powerful due to three central properties: decentralisation, data dispersed among
numerous computers, cryptographic linking applying maths codes to protect data, and
immutability, data records that cannot be altered.This paper discusses how BT develops Self-Sovereign Identity SSI systems, providing
individuals with complete control of their digital IDs and preventing mass identity theft. It
further discusses its applications in securing IoT devices and verifying the integrity and
authenticity of essential information. Key findings distilled from existing literature affirm the
technology's potential but outline principal stumbling blocks, such as the problem of scalability,
system velocity and legal disputes with data privacy legislation, such as the right to be
forgotten. The research concludes that concentrated development on standardised enterprise
solutions will render blockchain a critical, new layer of contemporary cyber security protection.
