Risks of Communication Using a Self-signed Certificate
When mobile terminals and devices are connected by Wi-Fi, a server certificate installed in the device is used for encrypted communication. The server certificate installed at the time of shipping is a self-signed certificate.
When using a self-signed certificate, there is a possibility of confidential information such as user names, passwords, etc. leaking when a man-in-the-middle attack occurs, such as a PC that assumes the device being installed in the intranet.
To prevent man-in-the-middle attacks and ensure strong security, it is necessary to install an authenticated server certificate in the device. Regarding installation of a server certificate, check with the administrator of the device.
