Mr. Rosenzweig formerly served as Deputy Assistant Secretary for Policy in the US Department of Homeland Security, and he is currently a distinguished visiting fellow at the Homeland Security Studies and Analysis Institute. He is also an advisor to the American Bar Association’s Standing Committee on Law and National Security and a contributing editor of the Lawfare blog. Mr. Rosenzweig is the author of Cyber Warfare: How Conflicts in Cyberspace Are Challenging America and Changing the World, coauthor of Winning the Long War: Lessons from the Cold War for Defeating Terrorism and Preserving Freedom, and coeditor of both National Security Law in the News: A Guide for Journalists, Scholars, and Policymakers and Whistleblowers, Leaks, and the Media: The First Amendment and National Security. Mr. Rosenzweig’s other Great Courses are Thinking about Cybersecurity: From Cyber Crime to Cyber Warfare and The Surveillance State: Big Data, Freedom, and You.
01: Stuxnet-The First Cyber Guided Missile
Your introduction to the fascinating-and fascinatingly dangerous-world of cybersecurity begins with the story of "Stuxnet." Learn how this unique piece of malware, which shut down a uranium enrichment facility in Iran, signaled the dawn of a new age in which viruses and other cyber threats can manipulate the physical world.
02: The Incredible Scope of Cyberspace
What makes the Internet so vulnerable is its ability to connect, and to be connected to, anyone and almost anything. Here, explore how cyberspace works. You'll learn what goes on behind the scenes of a simple Internet search, how a simple TCP/IP system functions, the five layers of connections that make up a conceptual "map" of cyberspace, and more.
03: The Five Gateways of Internet Vulnerability
Take a closer look at the cyber domain's inherent vulnerability to cyber threats. Professor Rosenzweig explains the five key gateways to this vulnerability, including the Internet's ability to destroy time and space; allow users to act in ways they can't in the physical world; and operate without international boundaries.
04: Of Viruses, Botnets, and Logic Bombs
Learn about some of the most dangerous ways people can exploit the Internet's vulnerabilities, including DDoS attacks (which flood websites with connection requests), "Trojans" (malware hidden inside an innocent piece of information), and "botnets" (which control computers like puppets). Then, investigate some common defense mechanisms that help pinpoint and capture these threats.
05: The Problem of Identity on the Network
Identification is perhaps the single most profound challenge for cybersecurity today. In this lecture, delve into the question of network anonymity and identity. Who maintains domain names? How can people obscure their identities for malicious purposes? How are network designers fighting back against this threat? What are the ethical problems involved in this issue?
06: Cyber Fraud, Theft, and Organized Crime
Professor Rosenzweig leads you on an examination of all-too-common instances of cybercrime that involve fraud and identity theft. You'll encounter crimes that mimic real-world ones (with a computer as the "weapon") and "computer crimes" that are only possible in the cyber world. Then, find out how law enforcement authorities are fighting back against organized, international cyber criminals.
07: Hacktivists and Insurgency
Enter the netherworld of hacktivism, or the use of computer hacking methods to stage protests and make political statements. In this lecture, learn to identify and distinguish the "good guys" from the "bad guys" by exploring real-world examples that illustrate the three major types of hacktivists: political activists, cyber insurgents, and mischief makers.
08: Nations at Cyber War
Turn now to the highest level of cyber conflict: a cyber war between nation-states. What is meant by the term "cyber war"? How does one fight a battle in cyberspace? What do the enemies look like? Do traditional international rules of armed conflict apply? How do we counter such an attack-and should we?
09: Government Regulation of Cyberspace
Join the debate about government regulation of cyberspace with this lecture that considers both sides of the issue. By looking at the debate in America over government oversight of cybersecurity (and whether we even need it at all), you'll be better informed about a topic that has serious ramifications for how you use the Internet.
10: International Governance and the Internet
Continue exploring rules and regulations about the Internet, this time on the international level. First, Professor Rosenzweig discusses existing Internet governance and the dynamics leading to change. Then, he assesses some of the barriers to effective international governance of the Internet. Is the current structure, with all of its flaws, better than the alternatives?
11: The Constitution and Cyberspace
Return to American policies on cybersecurity, this time focusing on the idea of government monitoring of the Internet. Start by learning all about how on-network monitoring systems work. After that, step back and examine how government monitoring is enforced and limited-but not prohibited-by the Constitution.
12: Big Data-"They" Know Everything about You
In the first of two lectures on personal data tracking and privacy, ponder the problem of "Big Data"-where your Internet searches can be tracked, your cellphone can broadcast your geographical location instantly, and your online purchases can be catalogued. It's a frightening aspect of cybersecurity, and one that, unfortunately, is here to stay.
13: Privacy for the Cyber Age
It appears our current conceptions of privacy in cyberspace will disappear. So what can we do about it? By exploring how the government and private sector use "Big Data"-and how "Big Data" can keep the government honest-you'll discover insights into how we can evolve our privacy laws while embracing new technologies.
14: Listening In and Going Dark
Learn how encryption and wiretapping work in cyberspace, and how both methods are becoming increasingly frustrating for law enforcement and national security officials. This "going dark" phenomenon, as you'll find in this eye-opening discussion, brings benefits and causes problems-and the solutions seem to bring problems of their own.
15: The Devil in the Chips-Hardware Failures
Hardware-based threats are one of the most vexing problems in the entire cybersecurity domain. How do we know that our machines will actually do what we tell them to do? Why is compromised hardware such a critical threat to cybersecurity? What are some possible solutions for dangers hidden in computer chips?
16: Protecting Yourself in Cyberspace
Get practical tips on how to reduce your own risk of danger online in your professional and personal life. You'll find out how to choose the most effective passwords, how to set up the most effective personal computer security systems, how to encrypt and erase personal data and documents, and much more.
17: Critical Infrastructure and Resiliency
Take an alternate approach to cybersecurity, this time focusing on resiliency and recovery. There may be good reason to think that creating a system that isn't immune to failure but is less likely to be attacked-and better able to operate even while under attack-is the best course of action.
18: Looking Forward-What Does the Future Hold?
Finish the course with a helpful summary of the main issues and arguments involved in the current state of cybersecurity throughout the world. Then, take an intriguing peek into the future to explore possible-and even radical-new developments that may shape this powerful and important topic for years to come.
