CYB-200 at Southern New Hampshire University is the starting point for cybersecurity study: the course where the field's vocabulary and core ideas are introduced.
SNHU's catalog says students gain familiarity with foundational cybersecurity concepts and terms. They learn the difference between adversarial and environmental threats and analyze how security practitioners respond to each.
The course also explores legal and human factors and how they influence organizational security strategies. It is a 3-credit undergraduate course, and SNHU lists it as a prerequisite for later courses such as CYB-220 and CYB-250.
Students new to IT sometimes find the volume of terminology the biggest hurdle. Others, already technical, are surprised by how much the course asks about people, law and strategy rather than tools.

What CYB-200 Covers
| Area from SNHU's description | What it means in practice |
|---|---|
| Foundational concepts and terms | Confidentiality, integrity, availability, risk, threats, vulnerabilities and controls |
| Adversarial threats | Threats from people with intent, such as criminals, insiders and nation-states |
| Environmental threats | Non-human threats such as fire, flood, power loss and hardware failure |
| Practitioner responses | How security teams prevent, detect and recover from each type |
| Legal and human factors | Laws, ethics, user behavior and organizational culture |
| Organizational strategy | How these factors shape an organization's security plan |
Key Concepts Explained
The CIA Triad
Confidentiality means only authorized people see information. Integrity means information is accurate and unaltered. Availability means systems and data are there when needed. Most security questions come back to which of the three is at risk.
Adversarial Versus Environmental Threats
The distinction in SNHU's description changes how you respond. Adversaries adapt, so defenses must anticipate intent; environmental threats do not adapt, so planning focuses on likelihood, resilience and recovery.
Example: A small clinic stores patient records on one local server. An adversarial threat is ransomware delivered by phishing: responses include staff training, email filtering and offline backups. An environmental threat is a burst pipe flooding the server room: responses include moving the server off the floor, environmental sensors and off-site backups. Both threats point to backups, but for different reasons.
Human and Legal Factors
Many incidents begin with a human action, such as clicking a link or reusing a password. Laws and regulations also shape what organizations must protect and report. Strategy that ignores people and law is incomplete, which is why SNHU builds both into the foundations course.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Concept explanation | Accurate use of terms | Define, then give a short example |
| Threat scenario analysis | Classifying and responding to threats | Label each threat, then match a response |
| Human factors discussion | Understanding people as a risk and a defense | Use real behaviors and practical measures |
| Strategy project | Linking concepts into a plan | Connect legal, human and technical points to one organization |
Terms You Will Use All Term
CYB-200 is a vocabulary course as much as a concepts course. Later CYB courses assume you can use these terms precisely, so it pays to learn the differences now.
| Term | Meaning |
|---|---|
| Asset | Anything of value to protect, such as data, systems or reputation |
| Threat | A potential cause of harm, adversarial or environmental |
| Vulnerability | A weakness a threat could exploit |
| Risk | The chance and impact of a threat exploiting a vulnerability |
| Control | A measure that reduces risk: technical, administrative or physical |
A common mistake is calling everything a threat. "Unpatched software" is a vulnerability; "a criminal group exploiting it" is the threat; the chance of a breach and its cost is the risk.
Where Students Get Stuck
- Mixing up threat, vulnerability and risk. A threat exploits a vulnerability; risk combines likelihood and impact.
- Tool-only answers. SNHU's description stresses legal and human factors; include them.
- Ignoring environmental threats. Natural and accidental events are part of the course.
- Vague examples. Use a specific organization and situation to show understanding.
Study Tips for CYB-200
- Build your own glossary as you go; review it weekly.
- Read one current security news story each week and classify the threat.
- Practice explaining the CIA triad with everyday examples.
- Keep notes on laws and regulations mentioned in readings for later courses.
