Configuring the Browser Functions

Precautions for Using the Browser Function

The communication between the MFP and the server via a Web browser is exposed to the risk of
unauthorized viewing and modification. Because of this, it is recommended to install the site certificates
issued for the Web sites the MFP is allowed to browse and enable the machine's Site Certificate Check
function in advance. By allowing the machine to access only the Web sites whose certificates are
installed in the machine, you can prevent access to unauthorized Web sites.
It is recommended to enable [Site Certificate Check] especially when sending data using Extended
JavaScript.
To enable [Site Certificate Check], it is necessary to enable the machine's SSL function and install site
certificates.
For details about configuring SSL, see page 133 "Configuring SSL/TLS".
For details about installing site certificates, see page 164 "Configuring IEEE 802.1X Authentication".
The machine's Site Certificate Check settings can be specified only via Web Image Monitor.
See the related articles in the Web Image Monitor Help.
If [Site Certificate Check] is disabled and the user accesses an untrusted Web site, a warning message
may appear.
If this is the case, the connected Web site may have a security problem. In such a case, the machine
administrator must refer to page 243 "Troubleshooting", and then instruct the users to take appropriate
measures accordingly.
Further, even if such a message does not appear, to minimize the risk of information leakages and
unauthorized modification, the administrator should instruct the users to check the certificates and URLs
of the connected Web sites so that access to unauthorized Web sites can be prevented.
Untrusted Web site
An "untrusted Web site" meets any of the following criteria:
• Its certificate has not been issued.
• Its certificate has been issued by an unknown source.
• Its certificate has expired.

Troubleshooting

If the connected Web site has a security problem, a message may appear.
If this is the case, the machine administrator must check the message and instruct the users to take
appropriate measures accordingly.
