Lesson 1: Advanced Concepts in Cybersecurity

Theory & Frameworks for Modern Defense

1. Introduction and Learning Objectives

Welcome to Lesson 1, where we move beyond basic perimeter defense and delve into the advanced theoretical frameworks and conceptual models that define modern cybersecurity strategy. Effective defense today requires understanding the adversary's mindset, the lifecycle of an attack, and the principles of resilience rather than just prevention.

Learning Objectives

Upon completion of this lesson, students will be able to:

1. Analyze the structure and utility of the MITRE ATT&CK Framework for threat modeling and defensive gap analysis.
2. Differentiate between the stages of the Cyber Kill Chain and the Diamond Model of Intrusion Analysis.
3. Explain the core tenets of Zero Trust Architecture (ZTA)
