Description
A self-paced course on the working practice of a security architect: understanding what the organisation must protect, modelling how it could be attacked, selecting controls that fit, and documenting a design other engineers can build. Six modules cover the architect’s role, core design principles, threat modelling, identity and network design, data protection and cryptography, and producing architecture deliverables that survive review.
Written for engineers and analysts moving toward architecture roles in defence, aerospace and other regulated environments. Tech Skills Library is independent and issues no certification, credential or licence.
What is included
Self-paced online course with 6 modules and 18 lessons, lifetime access to the course content, and a Certificate of Completion badge when every lesson is marked complete.
