DROVE Method: Essential Cybersecurity Practices for Travelers

The DROVE method (Data, Réseau/Network, Oral, Vol/Theft, Ecran/Screen) outlines critical cybersecurity practices for professionals on the move. Below are key mistakes to avoid and actionable steps to secure your data.

Data (Données)

❌ Avoid:

• Writing MAC addresses or work phone numbers on devices.
• Unnecessary disclosure of personal/professional data in forms.

✅ You Should Know:

• Encrypt sensitive files using:

  Linux (GPG encryption) 
  gpg --encrypt --recipient '[email protected]' sensitive_file.txt 
  

  Windows (BitLocker) 
  manage-bde -on C: -usedspaceonly 
  

• Use password managers (e.g., Bitwarden, KeePass) to avoid physical notes.

Network (Réseau)

❌ Avoid:

• Connecting to public Wi-Fi without a VPN.

✅ You Should Know:

• Always use a trusted VPN:

  OpenVPN (Linux) 
  sudo openvpn --config client.ovpn 
  

• Verify Wi-Fi networks:

  nmcli dev wifi list  List available networks (Linux) 
  netsh wlan show networks  Windows equivalent 
  

Oral (Conversations)

❌ Avoid:

• Discussing sensitive topics in public.

✅ You Should Know:

• Use encrypted communication tools:
• Signal (for calls/messages).
• ProtonMail (for emails).

Theft (Vol)

❌ Avoid:

• Leaving bags unattended or unsecured.

✅ You Should Know:

• Enable device tracking:

  Find My Device (Linux alternative) 
  sudo apt install prey 
  

• Use USB data blockers to prevent juice-jacking.

Screen (Écran)

❌ Avoid:

• Working on sensitive documents without a privacy screen.

✅ You Should Know:

• Lock screens automatically:

  Linux (GNOME) 
  gsettings set org.gnome.desktop.session idle-delay 300 
  

  Windows 
  powercfg /change standby-timeout-ac 5

What Undercode Say

Travel cybersecurity hinges on prevention and encryption. Key takeaways:
1. Encrypt everything: Use LUKS (Linux) or BitLocker (Windows).
2. Avoid public Wi-Fi: If unavoidable, use `sshuttle` for secure tunneling:

sshuttle -r user@vpnserver 0.0.0.0/0 

3. Physical security: Store devices in car trunks, not seats.
4. USB safety: Never plug untrusted USB drives. Scan first:

sudo apt install clamav && clamscan /dev/sdb1 

5. Backup: Use `rsync` for encrypted backups:

rsync -avz --progress -e "ssh -i ~/.ssh/id_rsa" /local/folder user@remote:/backup 

Expected Output:

A hardened travel workflow combining encryption, VPNs, and physical vigilance to mitigate risks.
