Securing Enterprise Infrastructure Principles

🎙 Section 3.2 — Apply Security Principles to Secure Enterprise Infrastructure Welcome to Section

3.2. In the last section (3.1), we looked at how systems are built

— the architecture models. Now in Section 3.2, we’ll look at how to secure those

systems once they’re built. Think of this section as all the practical ways to harden,
