Lesson 1 — What is cybersecurity?
Cybersecurity is the practice of protecting devices, accounts, networks, and information from unauthorized access, damage, or disruption. It includes technology, processes, and everyday habits.
Lesson 2 — Threats, vulnerabilities, and risk
A threat is something that could cause harm. A vulnerability is a weakness. Risk considers how likely a threat is to exploit a weakness and how much impact it could have.
- Keep software updated.
- Use reputable security tools and backups.
- Be cautious with unexpected attachments and links.
Lesson 3 — Passwords and multifactor authentication
Use long, unique passwords for each account. A password manager can help. Turn on multifactor authentication (MFA), which adds another verification step beyond a password.
Lesson 4 — Spotting phishing
Phishing messages try to trick people into revealing information or opening unsafe links. Check the sender and destination carefully, be skeptical of urgent requests, and verify unusual messages through a separate trusted channel.
Lesson 5 — Safer devices and networks
Install updates, lock your devices, use screen locks, back up important files, and secure your Wi-Fi with modern encryption and a strong router password. Avoid entering sensitive information on sites that don't use HTTPS.
