6.3.4 Switching Telnet/Internet/SSH access on/off
The web server copies a Java applet for the web-based interface to your
computer. The applet then communicates with the device by SNMPv3
(Simple Network Management Protocol). The web-server of the device
allows you to configure the device through the web-based interface. You can
switch off the web server in order to prevent the applet being copied.
6.3.5 Web access through HTTPS
The HTTPS communication protocol (HyperText Transfer Protocol Secure)
helps protect data transfers from interception. The device uses the HTTPS
protocol to encrypt and authenticate the communications between web
server and browser.
