Cybersecurity: 5 Life-Saving Practices (That Really Work)

In the digital world, security should be as strict as in the physical one. Here are five essential cybersecurity habits to adopt:

1. Stay Suspicious

📩 Doubtful email? Always verify the sender before clicking any links.
🚨 Quick tip: Hover over links to see the actual URL before clicking.

2. Use Strong Passwords & 2FA

🔑 Never reuse passwords—each service should have a unique one.

🔒 Enable Two-Factor Authentication (2FA) wherever possible.

💡 Password Manager Recommendation: KeePass (approved by ANSSI).

3. Protect Yourself Outside the Office

📶 Avoid public Wi-Fi—use a mobile hotspot or VPN instead.

🛡️ Never leave devices unattended in public spaces.

4. Backup Regularly

💾 Follow the 3-2-1 rule:

  • 3 copies of your data
  • 2 different storage types (e.g., HDD + cloud)
  • 1 offline backup (external drive)

5. Report Suspicious Activity Immediately

⚠️ Notice something strange? Disconnect immediately (but don’t shut down the device!).

🖥️ Alert your IT team right away.

🔐 Cybersecurity isn’t just about tools—it’s about habits.

You Should Know:

🔐 Password Security Commands (Linux/Windows)

  • Generate a strong password (Linux):
    openssl rand -base64 16 
    
  • Check password strength (Windows PowerShell):
    Test-NetConnection -ComputerName google.com -Port 443 
    

🛡️ VPN & Network Security

  • Connect to OpenVPN (Linux):
    sudo openvpn --config client.ovpn 
    
  • Check active connections (Windows):
    netstat -ano 
    

💾 Backup & Data Protection

  • Automate backups (Linux – cron job):
    crontab -e 
    0 3    tar -czvf /backup/$(date +\%Y\%m\%d).tar.gz /important_data 
    
  • Verify backup integrity:
    sha256sum backupfile.tar.gz 
    

📡 Wi-Fi Security Checks

  • Scan nearby networks (Linux):
    nmcli dev wifi list 
    
  • Disable unsafe Wi-Fi auto-connect (Windows):
    netsh wlan set profileparameter name="PublicWiFi" connectionmode=manual 
    

What Undercode Say:

Cybersecurity is a continuous process, not a one-time setup. Always:
✅ Update software regularly (sudo apt update && sudo apt upgrade -y).
✅ Monitor logs (journalctl -xe for Linux, `Get-EventLog` in PowerShell).

✅ Use encryption (`gpg -c secretfile.txt`).

✅ Disable unused services (`sudo systemctl disable servicename`).

🔮 Prediction: Cyberattacks will increasingly exploit weak human habits—automated phishing and AI-driven social engineering will rise.

Expected Output:

A structured, actionable cybersecurity guide with real-world commands and best practices.
