2.2
- Guarantee of customer engineer (CE):
A supervisor or an administrator can use the Enhanced Security mode after confirming that a service
contract has been signed with a customer engineer (CE). Clearly state in the service contract that the
customer engineer (CE) will not engage in any fraudulent actions.
- Secure LAN:
Be sure to connect the machine to a local area network protected by firewall in order to prohibit access
from external networks. Be also sure not to have any illicit device connected to the LAN.
- An administrator should designate the installation location to be available only for product users. Install
the machine in a place securely locked during the night, and during the day in a place that allows the
administrator to monitor the machine, so that any parts such as an HDD should not get stolen or any
special device such as an internal analyzer should not be hooked up to the machine. Equipment re-
moved from the main body, such as an HDD, should also be managed similar to the main body.
- An administrator is required to be present at customer engineer (CE) works such as installation or main-
tenance.
- An administrator should check at regular intervals that the date/time setting is correctly made on the
machine.
2.2.3 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 da-
ta, which are TIFF format, PDF format, and PS data. The image area of memory or HDD with AHA com-
pressed 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 password and account password should be comprised of 8 alphanumeric characters (the alphabetic
characters are case-sensitive). For the administrator password, the following 32 symbols can be used in ad-
dition to alphanumerics (case-sensitive) to comprise 8 characters:
-^\@[]:;,./!"#$%&'()=~|`{+*}<>?_
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. If you enter 64 or
more characters, the last entered character will be identified as the 64th character.
The HDD lock password should be made from 8 to 32 alphanumeric characters (case-sensitive). If you enter
32 or more characters, the last entered character will be identified as the 32nd character.
The HDD lock password should be made from 8 to 32 alphanumeric characters (case-sensitive). If you enter
32 or more characters, the last entered character will be identified as the 32nd character.
As for the CE password, administrator password and account password, the machine recognizes the last en-
tered character as the eighth character if 8 or more characters are entered.
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.
