Cybersecurity and National Security: AI, Hackers, and Digital Defense

The digital realm has become the primary battleground for global power, where invisible lines of code can disrupt critical infrastructure and national defense. Understanding how modern adversaries operate is no longer just for technical specialists—it is essential for anyone navigating today's interconnected world. In this text-based course, you will transition from a curious observer to a knowledgeable analyst of global cyber threats. You will explore the history of hacking, dissect modern cyber campaigns, and understand the strategic intersection of artificial intelligence, surveillance, and national defense. What you'll learn: - Learn the fundamental concepts of national security, cyberspace, and the history of digital espionage. - Analyze the cyber kill-chain to understand how attackers plan, execute, and conceal their operations. - Understand the dual role of artificial intelligence as both a powerful tool for cyber warfare and a modern shield for automated defense. - Explore the history of cryptography, the Crypto Wars, and how encryption policies impact global privacy and surveillance. - Apply modern security frameworks, including zero-trust principles, to counter sophisticated state-sponsored threats. This course begins with foundational definitions of cybersecurity and national sovereignty before moving into the technical phases of cyberattacks, encryption debates, and the emerging threat of AI-driven warfare. You will progress through structured text lessons and practical case studies designed to build analytical thinking. Designed entirely for beginners, this course requires no prior technical background or programming experience.
