Security Feature Settings
When setting IPsec/IP filtering or IEEE802.1X, it is recommended that you access Web Config using SSL/TLS to
communicate settings information in order to reduce security risks such as tampering or interception.
Make sure you configure the administrator password before setting IPsec/IP filtering or IEEE802.1X.
Also, you can use Web Config by connecting the printer directly to the computer using an Ethernet cable, and then
entering the IP address into a web browser. The printer can be connected in a secure environment after the security
settings have been completed.

Advanced Security Settings
Feature type
Controls the protocols and
services to be used for
communication between
printers and computers, and
it enables and disables
features.
The communication content
is encrypted with SSL/TLS
communications when
accessing to the Epson server
on the Internet from the
printer, such as
communicating to the
computer via web browser,
using Epson Connect, and
updating firmware.
You can set to allow severing
and cutting off of data that is
from a certain client or is a
particular type. Since IPsec
protects the data by IP packet
unit (encryption and
authentication), you can
safely communicate
unsecured protocol.
Only allows authenticated
users to connect to the
network. Allows only a
permitted user to use the
printer.

Security Settings and Prevention of Danger
What to set
A protocol or service that is
applied to features allowed or
prohibited separately.
Obtain a CA-signed
certificate, and then import it
to the printer.
Create a basic policy and
individual policy to set the
client or type of data that can
access the printer.
Authentication setting to the
RADIUS server
(authentication sever).

What to prevent
Reducing security risks that
may occur through
unintended use by
preventing users from using
unnecessary functions.
Clearing an identification of
the printer by the CA-signed
certification prevents
impersonation and
unauthorized access. In
addition, communication
contents of SSL/TLS are
protected, and it prevents the
leakage of contents for
printing data and setup
information.
Protect unauthorized access,
and tampering and
interception of
communication data to the
printer.
Protect unauthorized access
and use to the printer.
