📌 Why Cyber Hygiene Matters

Most attacks don’t rely on hackers using advanced tools.
They rely on:

• Outdated software
• Weak passwords
• Unsafe browsing habits
• Clicking suspicious links
• Poor Wi-Fi security

These vulnerabilities often lead to malware infections, which we explain in detail under Malware & System Defense.

Practicing good cyber hygiene protects you from the majority of common threats.

📝 Quick Cyber Hygiene Checklist

✔ Passwords & Authentication

• Use strong, unique passwords for each account
• Enable multi-factor authentication (MFA) wherever possible
• Do not reuse passwords between important accounts
• Use a password manager to keep track of everything

If you’re unfamiliar with MFA, you can find simple explanations in the Cyber & Digital Security category.

✔ Device Security

• Keep your operating system updated
• Update browsers and apps regularly
• Install reputable antivirus or anti-malware tools
• Remove unused apps you no longer trust
• Do not install apps from unknown sources

See our detailed protection recommendations in Malware & System Defense.

✔ Network Safety

• Use WPA3 or WPA2 encryption on your Wi-Fi
• Change default router login credentials
• Disable WPS and remote administration
• Create a guest network for visitors or IoT devices

A full guide to improving your router security is available under Network & IoT Hardening.

✔ Safe Browsing Habits

• Avoid clicking suspicious links
• Don’t download email attachments you weren’t expecting
• Only visit websites with HTTPS
• Avoid using public Wi-Fi without a VPN
• Be cautious of pop-ups claiming your device is infected

✔ Email & Communication Security

• Double-check the sender address before trusting an email
• Look for spelling mistakes or strange formatting
• Be skeptical of urgent or threatening messages
• Do not share personal information via email

Phishing is one of the most common threats — explore it deeper in Fraud & Scams.
