Thinking About Cybersecurity, a Great Courses program Cyberspace is the 21st century’s greatest engine of change. And it’s everywhere. Telecommunications, commercial and financial systems, government operations, food production—virtually every aspect of global civilization now depends on interconnected cyber systems to operate; systems that have helped advance medicine, streamline everyday commerce, and so much more. Which makes keeping these systems safe from threat one of the most pressing problems we face.

There are billions of Internet users connected to one another, and every minute, these parties create mind-boggling amounts of new information and data. Yet because cyberspace is so vast, flexible, and unregulated (and because it grows in leaps and bounds every year), all these users are highly vulnerable to dangers from cyber criminals, rogue nation-states, and other outside forces.
