The Role of Cyber Threat Intelligence in Protecting National Infrastructure.

Cyber threats pose a significant risk to national infrastructure, with critical sectors such as energy, transportation, healthcare, and finance increasingly targeted by sophisticated cyberattacks. Cyber Threat Intelligence (CTI) plays a crucial role in enhancing cybersecurity defenses by providing actionable insights into emerging threats, adversarial tactics, and vulnerabilities. This paper explores the role of CTI in protecting national infrastructure, emphasizing its contribution to threat detection, risk mitigation, and incident response. We examine the integration of artificial intelligence and big data analytics in CTI to improve threat prediction and real-time analysis. Additionally, we discuss the challenges in implementing CTI, including information sharing barriers, data privacy concerns, and the evolving nature of cyber threats. By analyzing case studies of cyber incidents and successful CTI implementations, this research highlights best practices for strengthening national cybersecurity frameworks. The findings underscore the necessity of a proactive and intelligence-driven approach to safeguard critical infrastructure against ever-evolving cyber risks. DOI:https://doi.org/10.52783/pst.1699
