Cybersecurity Situational Awareness (CSA) for the IoT and AI-driven model applications provides a comprehensive exploration of how AI and advanced models can be leveraged to strengthen the cybersecurity posture of the rapidly expanding IoT. As billions of IoT devices continue to permeate critical sectors such as healthcare, energy, transportation, agriculture, and smart cities, the need for adaptive and intelligent defense mechanisms has never been more urgent. The ebook begins with a background chapter that contextualizes the evolution of IoT, highlighting both its transformative potential and its inherent vulnerabilities. It outlines how traditional security mechanisms, such as firewalls and intrusion detection systems, are increasingly unable to cope with the scale, heterogeneity, and sophistication of modern cyber threats. This sets the stage for introducing CSA as a central framework for monitoring, understanding, and projecting the evolving security landscape.
