Abstract : The escalating complexity and frequency of cyber threats have exposed the inadequacies of conventional, centralized security architectures. This paper investigates the application of blockchain technology as a transformative framework for enhancing cybersecurity. We propose a modular, blockchain-based security architecture that leverages decentralized consensus, cryptographic immutability, and programmable smart contracts to fortify data integrity, identity management, and system resilience. Our approach is validated through a qualitative comparative analysis of traditional and blockchain-augmented security models, supported by real-world use cases and expert evaluations. We further delineate the architectural components necessary for practical deployment and identify key implementation challenges such as scalability, energy efficiency, and interoperability. This study contributes to the cybersecurity literature by offering a structured framework that integrates blockchain with modern security paradigms, paving the way for more resilient and autonomous defense mechanisms across critical digital infrastructures.

Keywords : Blockchain Technology, Cybersecurity, Decentralization, IoT, Smart Contract.
