The evolving landscape of cybersecurity is being significantly reshaped by Artificial Intelligence (AI) and Generative AI, marking a transition into the Age of Intelligent Cybersecurity. Both cybercriminals and defenders utilize AI, with attackers employing it for sophisticated phishing and malware creation, while defenders leverage it for predictive threat intelligence and automated incident response. This duality underscores the necessity for organizations to adopt AI governance and multi-layered defense strategies to combat increasing threats. The integration of human expertise with AI technologies is essential for developing resilient cybersecurity frameworks that can adapt to emerging challenges and maintain trust in an era defined by digital warfare. The ongoing battle of algorithms emphasizes the importance of ethical AI use for safeguarding critical information and infrastructure.
