The Role of Artificial Intelligence and Blockchain for Future Cyber Threat Intelligence

Considering the rapid integration of smart technologies into our daily lives, the risk of cyber-attacks has increased and mitigating such risks in smart systems requires practical approaches. Cyber Threat Intelligence (CTI) has been considered a powerful technique for developing successful and mature proactive tools for cyber threat detection and mitigation. However, with evolving threat landscape, it has been crucial to develop and implement comprehensive, robust CTI solutions to ensure the security and resilience of interconnected smart systems. Recently, the two emerging technologies of artificial intelligence (AI) and blockchain have gained significant attention in the field of cybersecurity. AI and blockchain offer novel ways to improve security, privacy, and efficiency in different areas of cyber security. However, a lack of research on the integration of AI and blockchain in CTI is considered. In this paper, we propose the integration of AI and blockchain in CTI and assess their advantages and disadvantages to explore how AI and blockchain can enhance CTI. We also discuss the role of AI and blockchain across various phases of a CTI life cycle in a detailed manner.
