The integration of Artificial Intelligence (AI) in cybersecurity and forensic science represents a transformative shift in addressing today's complex digital security challenges. As cyber threats evolve in sophistication and frequency, AI-driven approaches provide a proactive and adaptive solution to enhance threat detection, prevention, and investigation capabilities. This chapter provides an overview of the role AI plays in advancing cybersecurity and forensic methodologies, with a focus on machine learning, deep learning, and natural language processing techniques. We examine the ways AI enhances traditional cybersecurity frameworks and forensic processes, such as anomaly detection, incident response, and digital evidence analysis. Additionally, we discuss the dual-use potential of AI, including both defensive and adversarial applications, as well as the ethical and privacy implications arising from its use in security-sensitive fields. By contextualizing the impact of AI in cybersecurity and forensic science,
