Overall, a combination of preventive measures, proper maintenance, and material selection helps to ensure effective corrosion protection in airplanes. **

Security over VPN can be ensured through several measures. Firstly, using strong encryption protocols such as AES (Advanced Encryption Standard) can help protect the data being transmitted over the VPN. Additionally, implementing multi-factor authentication can add an extra layer of security by requiring more than just a password for access. Regularly updating and patching the VPN software and ensuring that only authorized users have access to the VPN can also help enhance security. Finally, monitoring and logging VPN activity can help detect and respond to any potential security threats. **
