Fast recall of precise meanings accelerates problem solving on exam day, so this episode presents a plain-language mini-glossary woven into context rather than alphabet soup. We clarify frequently tested pairs that candidates mix up: authentication versus authorization, vulnerability versus threat versus risk, qualitative versus quantitative analysis, and preventive versus detective versus corrective controls. We define key mechanisms—tokenization, hashing, encryption, digital signatures, federation, single sign-on, microsegmentation—and map each to the control objective it serves. We also anchor network and platform terms—DMZ, bastion, jump host, overlay network, hypervisor, container runtime—so you can place them instantly in an architecture.

We reinforce definitions with short, vivid use cases that double as memory hooks. Hashing proves a file was not altered; encryption keeps its contents private; a digital signature ties that proof to a specific identity. MFA strengthens authentication, while RBAC limits authorization by job function; ABAC adds context like device posture. A compensating control documents how you meet a requirement another way, with evidence and risk analysis. For continuous monitoring, think data feeds plus thresholds producing decisions; for incident response, think roles plus timelines preserving chain of custody. Each term is tied to at least one artifact—log entry, ticket, signature, policy—so knowledge ends in something you can show. With meanings anchored to outcomes and evidence, you will decode stems quickly and eliminate distractors that misuse jargon.
