Proton Technologies VPN Kill Switch for Linux

The proton-vpn-killswitch module is an essential component that defines the "kill switch" interface for the ProtonVPN VPN. The main function of a "kill switch" in a VPN is to ensure that in the event of an unexpected disconnection from the VPN, all network traffic is immediately stopped. This prevents sensitive data from being transmitted without the protection of the VPN, thus ensuring user privacy and security.

Although the proton-vpn-killswitch module defines the interface, it does not implement specific functionality by itself. Instead, it allows other implementations, such as proton-vpn-killswitch-network-manager, to realize the defined functionality. This promotes a modular and extensible architecture, where different components can be developed and updated independently.

Its purpose is:

   - Provide Network Security: Ensures that, in the event of any failure in
     the VPN connection, network traffic is interrupted to prevent sensitive
     information from being exposed to the public network or unsecured
     networks.
   - Modularity and Extensibility: Facilitate the addition and integration
     of different kill switch methods, such as those specific to different
     network managers (e.g. Network Manager), operating systems or network
     environments. This allows ProtonVPN to support a variety of user
     configurations and needs.
   - Consistency in Implementation: Ensure that all kill switch implementations
     in ProtonVPN follow a consistent standard, providing a uniform and
     reliable user experience regardless of the platform or environment
     in which ProtonVPN is being used.
