This week introduces security as a foundational discipline rather than a collection of scattered tools. Learners will examine the enduring concepts of confidentiality, integrity, and availability, understanding how these principles anchor defenses across decades of technological change. The CIA triad is presented as a lens through which design choices can be evaluated, while resilience, governance, and accountability extend the model to reflect today’s enterprise priorities. By framing security as practice and architecture, students gain an appreciation for why controls must work in concert rather than isolation.

Alongside principles, learners explore the role of frameworks in organizing risk. NIST CSF, ISO standards, and FAIR are introduced as structures that translate abstract ideas into actionable programs. Case studies such as the Colonial Pipeline incident illustrate the dangers of poor governance and lack of segmentation, highlighting the systemic consequences of design flaws. By the end of this week, students will see that security foundations endure precisely because they adapt across contexts, enabling both technical rigor and strategic leadership.
