Episode 8 — Design defensible security architecture by mapping threats to layered controls

This episode focuses on making architecture choices defensible under audit and incident pressure, which GSOM tests by asking you to pick controls that reduce risk without relying on a single point of failure. You’ll define layered defense as coverage across prevention, detection, response, and recovery, and then practice mapping threats to control types such as segmentation, identity hardening, endpoint controls, logging, and safe administrative pathways. We’ll use scenarios to show how architecture affects SOC outcomes: a flat network increases containment cost, weak key management undermines encryption claims, and missing centralized logging turns investigations into guesswork. You’ll also cover best practices for trust boundaries, least privilege, and secure management planes, plus troubleshooting considerations like exception sprawl and “shadow” paths that bypass intended controls.
