Threat Modeling Basics
The Threat Modeling Basics course teaches structured approaches to identifying and mitigating threats during system design. Learners practice STRIDE, attack trees, data flow diagrams, and lightweight modern frameworks (Shostack's four-question framework, MITRE ATT&CK), and produce concrete mitigations for realistic systems.
Zero Trust Concepts
The Zero Trust Concepts course teaches the principles, architecture, and pragmatic adoption patterns of zero trust — from 'never trust, always verify' through identity-centric access, microsegmentation, ZTNA, and continuous verification — with cross-references to NIST SP 800-207, BeyondCorp, and modern policy engines.
