Enabling TLS Encrypted Communication for the Remote UI

You can encrypt communication between the machine and a Web browser on the computer by using Transport Layer Security (TLS). TLS is a mechanism for encrypting data sent or received over the network. TLS must be enabled when the Remote UI is used for specifying settings for IPSec (Pre-Shared Key Method), IEEE 802.1X authentication (TTLS/PEAP), or SNMPv3. To use TLS for the Remote UI, you need to set a key pair and enable the TLS function. Generate or install the key pair for TLS before enabling TLS (Configuring Settings for Key Pairs and Digital Certificates).

Start the Remote UI and log on in System Manager Mode. Starting Remote UI

Click [Settings/Registration].

Click [Network Settings]

[TCP/IP Settings].

Click [Key and Certificate...] in [TLS Settings].

Click [Register Default Key] on the right of the key pair you want to use.

Viewing details of a certificate
You can check the details of the certificate or verify the certificate by clicking the corresponding text link under [Key Name], or the certificate icon. Verifying Key Pairs and Certificates

Enable TLS for the Remote UI.

1	Click [Security Settings] [Remote UI Settings].
2	Click [Edit...].
3	Select the [Use TLS] check box and click [OK].

Restart the machine.

Turn OFF the machine, wait for at least 10 seconds, and turn it back ON.


Using the operation panel You can enable or disable the TLS encrypted communication from <Menu>. Use TLS Starting the Remote UI with TLS If you try to start the Remote UI when TLS is enabled, a security alert may be displayed regarding the security certificate. In this case, check that the correct URL is entered in the address field, and then proceed to display the Remote UI screen. Starting Remote UI Enabling TLS for e-mailing If the SMTP server and the POP3 server support TLS, you can enable TLS for communication with these servers (Configuring Advanced E-mail Settings). For more information about the SMTP server and the POP3 server, contact your Internet service provider or Network Administrator.
