7. Managing the Machine 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 p.136 "Configuring SSL/TLS". For details about installing site certificates, see p.174 "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 p.251 "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. Changing the Browser Settings You can change the default settings for the browser functions. 1. The machine administrator logs in from the control panel. 2. Press [Browser Features]. 248
