About this course
Cybersecurity is no longer a specialist concern. Every business, every team and every person with an email address is a target, and the basics that stop most attacks are learnable in hours, not years.
This course gives you a working mental model of security: what attackers want, how the most common attacks actually unfold, and the defensive habits and controls that break them. Along the way you will meet the vocabulary used in real security work, so job posts, news reports and audit findings stop sounding like a foreign language.
What you will learn
- How to think about security using the CIA triad and risk, instead of fear
- How phishing, malware and password attacks really work, step by step
- The defensive controls that stop most real-world incidents
- How multi-factor authentication, password managers, patching and backups fit together
- Where to go next: security roles, certifications and learning paths
Who this course is for
Students exploring a security career, professionals who want to stop guessing at security decisions, and anyone preparing for deeper NUEXUS certification trainings.
