Cyber Hygiene 101: Essential Practices for Everyday Users

In today’s digital world, good cyber hygiene is as crucial as brushing your teeth or washing your hands.
With cyber threats growing more sophisticated, even casual web browsing or social media use can expose you to risks.
Here’s how you can protect yourself and your data every day.

What Is Cyber Hygiene?

Cyber hygiene refers to routine practices that help keep your devices, data, and online activities safe
from threats like malware, phishing scams, and data breaches. Think of it as the digital equivalent of personal cleanliness—
small steps done consistently to prevent bigger problems.

1. Use Strong, Unique Passwords

  • Create complex passwords with a mix of letters, numbers, and symbols.
  • Avoid reusing the same password for different sites.
  • Consider using a reputable password manager to keep track of your credentials.

2. Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of security, requiring you to enter a code sent to your phone or generated by an app after you enter your password.
This makes it much harder for attackers to access your accounts.

3. Update Software Regularly

  • Keep your operating system, browsers, and apps updated.
  • Enable automatic updates wherever possible.
  • Software updates often patch severe security vulnerabilities exploited by attackers.

4. Be Wary of Suspicious Emails & Links

  • Don’t click on links or download attachments in unexpected emails or texts.
  • Look for red flags: misspellings, urgent requests for information, or generic greetings.
  • If in doubt, contact the sender using a trusted method to verify.

5. Secure Your Devices

  • Set a PIN, password, or biometric lock on all your devices—phones, tablets, laptops.
  • Don’t leave your devices unattended in public spaces.
  • Enable device tracking and remote wipe features in case they’re lost or stolen.

6. Use Trusted Networks

  • Avoid using public Wi-Fi for sensitive activities like online banking.
  • If you must use public Wi-Fi, use a virtual private network (VPN) to encrypt your connection.

7. Back Up Your Data

Regularly back up important files to an external hard drive or secure cloud service.
This ensures you don’t lose critical data if your device is compromised.

8. Log Out When Finished

Especially on shared or public computers, always log out of your accounts when you’re finished to prevent unauthorized access.

9. Practice Good Social Media Hygiene

  • Set your profiles to private.
  • Don’t overshare personal information that could be used for identity theft (like your full birthdate, address, or travel plans).

10. Stay Informed

  • Follow reputable cybersecurity blogs and news sites, or the official accounts of organizations like the Cybersecurity & Infrastructure Security Agency (CISA).
  • Training and awareness are key—stay updated on common scams and threats.
