Countermeasures against Unauthorized Access
This section describes countermeasures against an unauthorized access to the printer from outside. When
you use the printer via a network or you are an administrator, we recommend you read this section before
using the printer.
Four countermeasures below can be helpful against an unauthorized access.
Specify a Private IP Address
Restrict Communication Using Firewall or Wi-Fi Router
Specify a Password for the Printer
Apply higher security level for Wi-Fi connection
Note
• As the setting procedure described below is an example, it may be different from that of your printer.
For details, refer to your printer's manual.
Specify a Private IP Address
An IP address is a numeric label assigned to each device on the network. There are two types of IP
address. One is used for internet connection ("global IP address"), and the other is used for a local area
network such as an inhouse LAN ("private IP address").
If a global IP address is specified for the printer, many and unspecified users on internet can access to
the printer. As a result, you will face an increased risk of information leakage caused by an unauthorized
access from outside. On the other hand, if a private IP address is specified for the printer, users who can
access to the printer are confined to those on a local area network such as an inhouse LAN. Therefore,
we recommend you specify a private IP address for the printer.
The range of addresses used as a private IP address is shown below. Make sure whether a private IP
address is specified for your printer.
Range of private IP address
• 10.0.0.0 to 10.255.255.255
• 172.16.0.0 to 172.31.255.255
• 192.168.0.0 to 192.168.255.255
Procedure to check the IP address
Select
Setup
>
Device settings
>
LAN settings
on your printer to select a network connection method
and check the IP address. For the procedure to check and specify the IP address, refer to your printer's
manual.
Note
• Establishing an environment to protect an access from outside using a firewall can reduce a risk of an
unauthorized access even though a global IP address is specified for your printer.
