TLS Settings
TLS is a protocol for encryption for data sent over a network and is often used for communication via a Web
browser or an e-mail application. TLS enables secure network communication when accessing the machine in a
variety of situations, such as when using the Remote UI or distributing device information.
Key and Certificate for TLS(P. 739)
IPSec Settings
While TLS only encrypts data used on a specific application, such as a Web browser or an e-mail application,
IPSec encrypts the whole (or payloads of) IP packets. This enables IPSec to offer a more versatile security system
than TLS. Configuring the IPSec Settings(P. 743)
IEEE 802.1X Settings
If a device tries to connect and start communicating on an 802.1X network, the device must go through user
authentication in order to prove that the connection is made by an authorized user. Authentication information
is sent to and checked by a RADIUS server, which permits or rejects communication to the network depending
on the authentication result. If authentication fails, a LAN switch (or an access point) blocks access from the
outside of the network. The machine can connect to an 802.1X network as a client device.

Preventing Trouble Caused by Erroneous Sending
Address Book PIN
You can set an access number for important business contacts and other destinations in the Address Book that
you do not want to display to all users.
Book(P. 755)
Manage Address Book Access Numbers
You can prevent the leakage of sensitive or personal information from the Address Book by setting a PIN or
preventing certain destinations from being displayed in the Address Book. You can also hide the Address Book
itself. Hiding the Address Book(P. 755)
Restrict Address Book Use
Set whether to hide the Address Book and one-touch buttons. You can specify separate settings for Fax as well
as Scan and Send.
Limit New Destination
The destinations that can be specified when sending faxes or scanned documents can be restricted to those
registered in the Address Book or one-touch buttons, those registered in <Favorite Settings> or <Send to
Myself>, or those that can be searched on the LDAP server.
Implementing Security Measures
Erroneous sending to the wrong destination or careless mistakes such as
entering the wrong fax number can lead to leaks of confidential information.
The machine provides various measures for increasing security when
sending, such as limiting the destinations that can be sent to and forcing the
fax number to be entered twice before sending.
Use the following functions as security measures for preventing trouble
caused by erroneous sending.
