Becoming a cyber defender
A cyber defender is someone who uses their knowledge of cybersecurity to protect themselves, their family, and their community online. You do not have to be an adult or an expert to be a cyber defender — you can start right now, with the knowledge you already have.
Every time you use a strong password, spot a scam, report a problem, help a friend stay safe, or make a smart decision online, you are acting as a cyber defender. These small actions add up to make the internet safer for everyone.
Cybersecurity is one of the most important and fastest-growing fields in the world. The skills you are building now — critical thinking, attention to detail, and responsible online behavior — are the same skills that professional cybersecurity experts use every day.
Your cyber defender toolkit: Strong passwords, privacy awareness, scam recognition, safe downloading habits, kindness online, knowing when to ask a trusted adult for help, and sharing what you know with others.
The cyber defender’s code
Protect your accounts Use strong, unique passwords and never share them with anyone. Stay alert Question unexpected messages, links, and requests — if something feels off, it probably is.

Help others Share what you know with friends and family — the more people who understand cybersecurity, the safer everyone is. Think before you act Pause before clicking, posting, or sharing — one moment of thought can prevent a big mistake.
Cyber defenders make a difference
The more people who understand cybersecurity, the safer the internet becomes for everyone. By sharing what you have learned with friends and family, you multiply your impact. One person who knows how to spot a phishing email can protect an entire household.
If you are interested in cybersecurity as a future career, you are already on the right path. Programs like CyberPatriot, competitions, and certifications can help you build on what you are learning now. The world needs more cyber defenders — and it starts with curious, careful people like you.
