Episode 9: Glossary Essentials — Security and Protocol Terms

This episode focuses on the essential security and protocol terms you must understand for the Network Plus exam. It introduces concepts such as encryption, hashing, authentication, authorization, and non-repudiation, explaining how they form the building blocks of secure communication. The episode also explores widely used protocols like SSL, TLS, IPSec, and Kerberos, showing how each plays a role in securing traffic and user access. Knowing these terms is critical not only for exam success but also for applying best practices in real-world environments.

Beyond definitions, the episode explains how these terms are tested in both multiple-choice and performance-based exam items. For example, you will learn how to identify whether a question is asking about the role of authentication versus authorization, or when encryption protocols are applied at different layers of the OSI model. Practical context is also given, such as recognizing how hashing supports file integrity or how IPSec underpins secure VPN tunnels. These insights reinforce that understanding terminology is a foundation for recognizing how security is implemented across networks.
