A Conceptual Framework for Cybersecurity Threat Intelligence Sharing Using Blockchain-Based Systems

Abstract: Cybersecurity threat intelligence (CTI) is essential for identifying and mitigating cyberattacks. However, traditional CTI sharing mechanisms struggle with issues such as trust, data integrity, and stakeholder collaboration. This paper examines how blockchain technology can revolutionize CTI sharing through its inherent features of decentralization, immutability, and transparency. We propose a conceptual blockchain-based framework that facilitates secure and efficient threat intelligence exchange. The paper discusses theoretical foundations, outlines benefits and limitations, and suggests directions for practical implementation. Our findings indicate that blockchain technology holds significant promise for building a more resilient and trusted cybersecurity ecosystem
