Security observations

On Linux and Android supplicants it is required to install the .ca file generated during certificate generation in order to verify the RADIUS server's identity. In case the identity presented by the RADIUS server changes at any point, the supplicant fails to connect, and re-presents the user with the prompt for network credentials. It is possible to connect without installing the .ca file, but one needs to specify "No CA certificate required" or "Do not validate". In this case the supplicant will send credentials to any RADIUS server for that SSID without verifying its identity.

On Mac OS and iPhone supplicants, when connecting to the SSID for the first time, the server certificate's details are presented to the user and the user is asked if they want to trust the server. In case the identity presented by the RADIUS server changes at any point, the user will be prompted with a message, not containing any warning, sadly, that looks identical to the one displayed when connecting for the first time, where a user is extremely likely to press Trust once again. On Mac OS, it is also possible to copy the .ca file and install it, avoiding the prompt on first connect, on iPhone, on the iPhone this was tested on, this did not have any effect.
