Course description

In this course, we will develop a business- and risk-driven security architecture using the seven-step process introduced in course 3. Students will use threat modeling techniques to enumerate and prioritize cyberthreats and assess the associated information risks. Students will then create security requirements that address the highest priority risks while supporting business requirements and objectives.
