THE ROLE OF BLOCKCHAIN TECHNOLOGY IN ENHANCING IT SECURITY

Abstract

In the digital age, information technology (IT) systems face increasing threats from cyberattacks, data breaches, and unauthorized access. Blockchain technology, known for its decentralized and immutable structure, offers promising solutions to these challenges. This paper explores how blockchain enhances IT security by providing transparent, tamper-proof data storage, secure identity management, and improved trust in data integrity. It highlights the application of blockchain in areas such as secure communication, access control, and data provenance. Furthermore, the study discusses emerging trends and potential limitations in adopting blockchain for cybersecurity purposes. The findings suggest that integrating blockchain into IT infrastructures can significantly strengthen data protection and system resilience against evolving threats.
