Konica Minolta bizhub PRO 951
Specification & Installation Guide
Creating a Secure Environment
• Secure LAN: Be sure to connect the machine
to a local area network protected by firewall in
order to prohibit access from external networks.
• An administrator should designate the installation
location to be available only for product users.
• An administrator is required to be present
at customer engineer (CE) works such
as installation or maintenance.
Description of Enhanced Security Mode
Security functions will be enhanced as follows.
Protecting and Deleting of Remaining Data
After Being Used
There are two types of Image data stored in memory
or HDD: AHA compressed data and uncompressed
data, which are TIFF format, PDF format, and PS
data. The image area of memory or HDD with AHA
compressed data will be released after clearing the used
data. In normal mode, the data is not completely deleted,
which may allow for unauthorized reading of the data.
In Enhanced Security mode, the image area of memory
or HDD is overwritten with data unrelated to the image
before the area is released, irrespective of whether the
stored image data is compressed.
Enhanced Passwords
There are 5 different passwords provided for security
functions.
• CE password
• Administrator password
• User password
• Account password
• HDD lock password
The CE authentication password, administrator
password, and account password should be comprised
of 8 alphanumeric characters and/or symbols (the
alphabetic characters are case-sensitive).
The user password is normally made from 1 to 64
alphanumeric characters (case-sensitive); however,
the user password less than 8 characters will be
unavailable in the Enhanced Security mode.

The machine in the Enhanced Security mode also
refuses any entry for 5 seconds, if a wrong password
is entered for one of the 5 passwords mentioned above.
Should you forget any security-related password,
please take action as follows depending on the type
of password.
• For a user password or account password,
please contact your administrator.
• If you have forgotten the administrator password
or HDD lock password, please contact your
service
representative.
We recommend that each password should be
changed on a regular basis in order to prevent illicit
access or falsification of data.
Data Access
Ensure that a user is required to enter an enhanced
password which has been set by the administrator,
in order to save data into the user box stored in HDD
or output the stored data.
When saving scanned data into a user box, you can
improve security by setting an enhanced password.
Only administrators can delete folders and user boxes
in which scanned data resides. Once a user box attribute
has been changed, user authentication with an enhanced
password is required. User authentication is also required
for using saved scanned data.
Machine NIC Settings
While the Enhanced Security mode is activated,
the machine NIC cannot be used.
Blocking External Accesses
No access is allowed over telephone lines other than
CS Remote Care.
Create, Save and Analyze an Audit Log
A history of security function operations will be created
and saved as an audit log. Date and time, information
identifying the person who made the operation, details
of the operation, and results of the operation will be
saved, enabling analysis of unauthorized accesses.
This log will be overwritten if the audit area is depleted.
