- Change default router passwords and enable WPA3 encryption at home.
Example
A remote worker connects to a VPN while working in a coffee shop, ensuring their login credentials and company data remain secure.
5. Be Cautious with Emails and Links
Overview
Phishing attacks trick users into revealing personal information or downloading malware.
Best Practices
- Verify the sender before clicking on links or attachments.
- Look for suspicious URLs and check for HTTPS in website addresses.
- Use spam filters to block malicious emails.
Example
A person receives an email claiming to be from their bank but notices a misspelled domain name and avoids clicking the link, preventing a potential phishing attack.
6. Backup Data Regularly
Overview
Regular backups ensure you can recover your data in case of ransomware attacks, device failure, or accidental deletion.
Best Practices
- Use external drives or cloud storage solutions like Google Drive, Dropbox, or iCloud.
