Security+ Roadmap and Core Security Principles

This lesson sets the foundation for the CompTIA Security+ journey by explaining how the exam is organized, how to study with purpose, and which security concepts appear throughout the course. You will see the difference between learning isolated terms and building a mental model that connects people, process, and technology.

Professor Amit Kumar introduces the core principles you must know early: confidentiality, integrity, availability, authentication, authorization, accountability, non-repudiation, and least privilege. The lesson also clarifies essential vocabulary such as threat, vulnerability, risk, exploit, exposure, and control so later technical topics make sense in context.

By the end, you should understand what Security+ expects at a high level, how to approach the certification systematically, and why strong security starts with fundamentals rather than tools alone.
