Information Security Fundamentals: Core Concepts Course

Most people encounter security through incidents — a phishing email, a data breach in the news, a locked account. This course works the other way: it builds a clear picture of how security works before problems appear.
What this course covers
You will work through the core pillars of information security: confidentiality, integrity, and availability. Each concept is grounded in real scenarios — not abstract definitions. You will look at how attackers think, what they target, and why certain controls exist.
Threats and attack surfaces
The course examines common threat categories — social engineering, malware, insider risk, and network-level attacks. Each is covered with enough technical detail to be useful without requiring a background in networking or programming.
Controls and risk management
Security controls are not all technical. This section covers administrative, physical, and technical controls, and explains how organizations decide which risks to accept, mitigate, or transfer. You will practice basic risk assessment using simple frameworks.
Security is not a product you install. It is a set of decisions made continuously under uncertainty.
By the end of the course, you will be able to read a security policy, participate in a risk discussion, and identify gaps in basic security setups. This is a foundation — it takes consistent practice to build further.
Course materials include readings, scenario exercises, and short knowledge checks after each module.-
