8.9.1 Logging in and out using HTTPS

HTTPS can be used to protect the communication of Web authenticated login and logout operations from others. With Web authentication, communication is encrypted using the server certificate and key using SSL module mounted on the Switch, using a one-way authentication method that is based on the Switch as a server. If the following SSL is indicated, TLS is included. The following diagram shows the operation of SSL.

Figure 8-19 SSL operation

When you use HTTPS for login or logout operations, the packets that pass through the network are encrypted. The following figure shows Web authenticated communication between the Switch and a terminal using a HTTPS.

Figure 8-20 Web authentication communication between the device and the terminal using HTTPS

To use SSL, you must register a server certificate, private key, and intermediate CA certificate on the Switch. The default server certificate and private key are registered at the time of shipment from the factory. However, in the actual operation, you must create a server certificate, private key, and intermediate CA certificate that conform to the usage environment. The intermediate CA certificate is not registered at the time of shipment from the factory.
