Security

Confidential information is always at risk of being copied without permission
or subject to unauthorized access through the network. To protect documents
from these types of risks, not only can passwords be set, but also the Extended
Security function can be used to strengthen security.
For those who require ample document protection, we recommend that the Ex-
tended Security function be used.

Primary Security Functions

Protecting Stored Documents
Protects documents with a password when using Document Server or
Locked Print. Furthermore, the Extended Security function can protect
against a password-guessing attack. See p.141 "Extended Security Function".
Protecting Image Data Remaining in Memory
Protects image data remaining in memory. When a copying or printing job is
completed or a job is cancelled, the data is secure.
Authenticating Administrator
Protects essential functions for administrating document security with an ac-
cess code. See p.69 "Key Operator Code"

Extended Security Function

By setting a password, operations with documents such as printing, deleting, or
delivering can be restricted to authorized users and access denied to others.
However, a password is breakable. When the Extended Security function is
used, entering the wrong password 10 times will lock a document, protecting it
from illegitimate accesses.
For unlocking documents, see p.142 "Unlocking a Locked Document".
The documents that can be protected by the Extended Security function are as
follows. All documents must be set with a password to be protected by this func-
tion.
Documents stored in the Document Server by the following functions
• Document Server mode
• Copier function
• Scanner function
• Printer driver
