Enabling SSL/TLS

After installing the device certificate in the machine, enable the SSL/TLS setting using a web browser from networked computers. (We use Web Image Monitor installed on this machine.)

This procedure is used for a self-signed certificate or a certificate issued by a certificate authority.

1Open a web browser from a networked computer, and then log in to Web Image Monitor as the network administrator.

For details on how to log in, see Administrator Login Method.

2Point to [Device Management], and then click [Configuration].

3Click [SSL/TLS] under "Security".

4For IPv4 and IPv6, select "Active" if you want to enable SSL/TLS.

5Select the encryption communication mode for "Permit SSL/TLS Communication".

Select [Ciphertext Only], [Ciphertext Priority], or [Ciphertext / Cleartext] as the encrypted communication mode.

When you set "Permit SSL/TLS Communication" to [Ciphertext Only], communication will not be possible if you select a protocol that does not support a web browser, or specify an encryption strength setting only. If this is the case, enable communication by setting [Permit SSL / TLS Communication] to [Ciphertext / Cleartext] using the machine's control panel, and then specify the correct protocol and encryption strength.

To avoid the "The page cannot be displayed" message when you access Web Image Monitor without encryption, we recommend you select [Ciphertext / Cleartext].

6If you want to disable a protocol, click [Inactive] next to "TLS1.2", "TLS1.1", "TLS1.0", or "SSL3.0".

At least one of these protocols must be enabled.

7Under "Encryption Strength Setting", specify the strength of encryption to be applied for "AES", "3DES", and/or "RC4". You must select at least one check box.

Note that the availability of encryption strengths will vary depending on the settings you have specified for "TLS1.2", "TLS1.1", "TLS1.0", or "SSL3.0".

8Click [OK].

9“Updating...” appears. Wait for about one or two minutes, and then click [OK].

If the previous screen does not appear again after you click [OK], wait for a while, and then click the web browser's refresh button.

10Log out.

For details about logging out, see Administrator Logout Method.

Note

  • The SSL/TLS version and encryption strength settings can be changed, even under [Network Security].

  • Depending on the states you specify for "TLS1.2", "TLS1.1", "TLS1.0", and "SSL3.0", the machine might not be able to connect to an external LDAP server.
