A self-paced practitioner course in security architecture — designing controls that hold, documenting them so they survive review, and defending them to the people who fund and audit them. It covers six stages: architecture as a discipline, requirements and threat modelling at depth, reference architectures and patterns, control design across the domains, architecture review and assurance, and running the function.

This is the deep course, not the career track. It assumes you already know what a firewall and an identity provider do, and spends its time on how to decide, document and defend a design. Tech Skills Library is independent and issues no certification or credential.
