Module 1: Foundations of Zero Trust Architecture (ZTA)
Overview
This module explores the fundamental shift from traditional perimeter-based security to Zero Trust Architecture. Students will learn why the “castle-and-moat” approach is obsolete and how to implement identity-centric security controls.
