Blockchain & Distributed Ledger Technologies for Enhancing Network Security in Modern Digital Ecosystems

Abstract

The rapid growth of digital communication and interconnected systems has increased the complexity of maintaining network security. Traditional security mechanisms, although effective in certain contexts, often face challenges in handling distributed, large-scale, and dynamic network environments. Blockchain and Distributed Ledger Technologies (DLTs) have emerged as transformative solutions capable of enhancing network security through decentralization, immutability, and transparency. This paper explores the applications, benefits, challenges, and future prospects of blockchain and DLTs in network security. By leveraging these technologies, organizations can achieve higher data integrity, secure authentication, and resilient defense mechanisms against emerging cyber threats.
