Communication between the MFP and the server via a web browser is exposed to eavesdropping and data tampering. Because of this, it is recommended to install the site certificates issued for the websites the MFP is allowed to browse and enable the machine's Site Certificate Check function in advance. Access to unauthorized can be prevented by allowing the machine to access only the websites whose certificates are installed on the machine.
It is recommended to enable [Site Certificate Check] especially when you send 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 Configuring SSL/TLS Settings.
For details about installing site certificates, see 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 website may have security problems. In such a case, the machine administrator must refer to 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 leakage and data tampering, the administrator should instruct users to check the certificates and URLs of the connected websites so that access to unauthorized Web sites can be prevented.
Untrusted Web site
An "untrusted website" is as follows:
It does not issue any certificate.
An unknown source issues the site's certificate.
The site's certificate has expired.
