System Security Architecture

Design secure hardware and OS environments. Master Secure Boot, Trusted Execution Environments (TEE), and isolation technologies like ARM TrustZone.

Software security fails if the hardware is compromised. This course covers System Security Architecture. You will learn how the Root of Trust works, the mechanics of Secure Boot, and how Trusted Execution Environments (TEE) like ARM TrustZone isolate sensitive data (biometrics, keys) from the main OS. We also cover memory protection units (MPU/MMU) and side-channel attack mitigation. This is the foundation of security for mobile devices, consoles, and secure servers.
