Dive into how modern organizations build resilient defenses. The Attack Surface & Security Controls module breaks down how to map your digital footprint and implement layered security architectures to mitigate risk.

You will learn to calculate and reduce your attack surface, implement Defense in Depth and Zero Trust architectures, and classify security controls as preventive, detective, or corrective. By the end of this module, you will understand how to design a security posture that assumes breach, enforces strict access, and mitigates risk at every layer of the technology stack.
