Preventing Unauthorized Access
2KUU-003
This section describes the security measur
es on how to prevent unauthorized access from the external network. This is
a must-read for all users and administrators before using this machine, other printers, and multifunction machines
connected to the network. In recent years, a printer/multifunction machine connected to the network can offer you a
variety of useful functions, such as printing from a computer, operating from a computer using the remote function,
and sending scanned documents via the Internet. On the other hand, it is essential to take security measures to
reduce the security risk for information leakage, as a printer/multifunction machine has become more exposed to
threats, such as unauthorized access and theft, when it is connected to the network. This section explains necessary
settings you need to specify to prevent unauthorized access before using a printer/multifunction machine connected
to the network.
Security Measures to Prevent Unauthorized Access from the External Network
Assigning a Private IP Address(P. 7)
Using Firewall to Restrict Transmission(P. 8)
Specifying the TLS Encrypted Communication (P. 8)
Setting PIN to Manage Information Stored in the Machine(P. 8)
Assigning a Private IP Address
An IP address is a numerical label assigned to each device participating in a computer network. A "global IP address" is
used for the communication connecting to the Internet, and a "private IP address" is used for the communication
within a local area network, such as a LAN in the company. If a global IP address is assigned, your printer/
multifunction machine is open to the public and can be accessed via the Internet. Thus, the risk of information leakage
due to unauthorized access from external network increases. On the other hand, if a private IP address is assigned,
your printer/multifunction machine is closed to a local area network and can be accessed by only users on your local
area network, such as a LAN in the company.
Global IP Address
Can be accessed fr
om the external network
Private IP Address
Can be accessed from the users within a local area network
Basically, assign a private IP address to your printer/multifunction machine. Make sure to conrm the IP address,
assigned to the printer/multifunction machine you are using, is a private IP address or not. A private IP address is
found in one of the following ranges.
Ranges for Private IP addresses
● Fr
om 10.0.0.0 to 10.255.255.255
● From 172.16.0.0 to 172.31.255.255
● From 192.168.0.0 to 192.168.255.255
For information on how to conrm the IP address, see
Setting IPv4 Address(P. 33) .
● If a global IP addr
ess is assigned to a printer/multifunction machine, you can create a network environment
to reduce the risk of unauthorized access by installing security software, such as a rewall that prevents
