Required Operation after Updating the Firmware
Whether the MFP had already been attacked or not is not clear, since the private key of the MFP or
admin/user passwords can be stolen without any trace in such a case. To avoid information leak
using the stolen private key or illegal access using the stolen admin/user passwords, the following
operations are required:
1. Change admin and user passwords
Please enforce users to manage the new passwords properly and not to forget them.
2. Reissue SSL server certificate (not required for Neo MFP and Neo Printer)
The MFP SSL server certificate that was used before updating the firmware shall be revoked and
reissued.
When SSL certificate was used by default settings: Enter [Security Settings]-[SSL
Settings]-[Certificate Creation] from System Settings, enter appropriate information and click
“Submit”.
When CA-signed SSL certificate was introduced: Enter [Security Settings]-[SSL Settings]-[Make of
Certificate Signing Request(CSR)] from System Settings, enter appropriate information and click
“Execute”. Then send the created CSR to the CA. The CA signs a new certificate and sends it
back. Install the signed certificate from [Security Settings]-[SSL Settings]-[Installation of
Certificate]. Some major CAs offer free reissue of a certificate.
