LESSON 1

This video series from CS50 at Harvard University supports Lesson 1: Cybersecurity as a Business Risk by introducing cybersecurity as a core part of modern business strategy—not just a technical concern.

The videos explain what cybersecurity actually protects in a business, including data, systems, customers, and operational continuity. They show why cyber incidents impact revenue, trust, and daily operations, helping participants understand the real consequences of security failures beyond IT departments.

Participants are guided through the difference between IT risk and business risk, highlighting why cybersecurity decisions must be made at a management and organizational level. The videos also emphasize that perfect security does not exist, introducing realistic risk management rather than absolute protection.

Key cybersecurity terminology, including the CIA Triad (Confidentiality, Integrity, Availability), is presented to build a shared language for discussing risk. The concept of risk as likelihood × impact is used to help participants evaluate threats in a structured way.

Finally, through practical examples—such as a digital booking platform—the videos connect theory to real-world business scenarios. This helps participants see how cybersecurity risks arise in everyday digital services and why informed decision-making is essential.

Together, these videos provide the conceptual foundation needed to understand and apply the lesson topics in practice.
