General Security Concepts: what Security+ tests and how to prepare

The vocabulary domain. It defines the control types, security principles and change-management ideas the other four domains assume you already know, which is why weak scores here tend to drag everything else down. Study this domain first even though it looks like the easiest. Every scenario in Security Operations and Security Architecture is built on this vocabulary, and candidates who skim it here pay for it repeatedly later.
