1.2 Security Functions

1.2 Security Functions
Setting the Enhanced Security Mode to [ON] will validate the security function of this machine. For details of the settings of different security functions to be changed by turning [ON] the Enhanced Security Mode, see page 2-6.
A password that can be set must meet the requirements of the Password Rules. The machine does not ac­cept setting of an easily decipherable password. For details of the Password Rules, see page 1-9.
If a wrong password has been entered three cumulative times during password authentication, the machine determines that it is unauthorized access through Prohibited Functions When Authentication Error, prohibit­ing any further entry of the password. By prohibiting the password entry operation, the machine prevents un­authorized use or removal of data, thereby ensuring secured used of the machine. This function is not, however, governed by authentication by the ISO15408.
When the machine is to be discarded, or use of a leased machine is terminated at the end of the leasing con­tract, the data erase function overwrites and erases all data stored in all spaces of the HDD. The function also resets all passwords saved in the memory area on the MFP board to factory settings, preventing leak of data. For details of items to be cleared by data erase function, see page 1-9.

Check Count Clear Conditions

The following are the conditions for clearing or resetting the check count of the number of wrong entries at the time of authentication.
NOTICE
The check count is cleared or reset by restarting the machine. If there is any user who frequently turns ON and OFF the machine, warn him or her of the fact or take necessary steps.
