Unit 1 – Lesson 2 – “CIA Triad”
3 Days
This lesson begins with a look at data storage in the cloud. Cloud computing provides convenience, but there are tradeoffs in security. Our digital lives are stored in data centers around the world. Securing that data leads us to a model for information security known as the CIA (Confidentiality, Integrity, Availability) Triad.
Unit 1 – “What is Cybersecurity?”
11 Days
Unit 1 opens the topic of cybersecurity by examining some early hacks of telecommunication systems and the Internet. It begins with an exploration of early hacks and then transitions into what cyberspace is and engages students in the notion of cyberspace being a complex system. Next, the unit delves into what it means for the Internet to be an open architecture and explores how the openness of the Internet is both virtue and vice. The example of cloud storage is used to illustrate complexity. The unit brings sharp focus on why cybersecurity is needed and for whom cybersecurity is needed. Next, the unit offers the foundational model of CIA in a manner that both introduces these concepts and affords exploration of what they are and why they matter. The unit then explores how cybersecurity impacts the quality of people’s lives through an examination of digital participation worldwide and the rise of IoT. The unit ends with engaging students in the messy work of considering ethical obligations involved in cybersecurity and how complex systems are not easy to predict or model.
