What is unauthorized
access from the Internet?
• While you are accessing the Internet, malicious
individuals may attack (gain unauthorized access to)
your PC or router to destroy the data or use the line
without permission. If a router is installed between your
PC and the Internet, then NAT, IP masquerade, and other
address conversion functions of the router can provide
security to a certain degree. However, even in such
an environment, possible setting errors or inadequate
settings pose a similar risk.
• In addition to unauthorized accesses via the Internet, you
should also be aware of the risk of attacks by computer
viruses.
• Should the settings of the product be modified or the PC
system or data be destroyed, a massive amount of data
and monetary damages would be resulted. You must
configure filter settings of the product or take other
security measures to protect your system.
Outline of unauthorized accesses and
security measures
A particular attention is required if a
global IP address is assigned to your
LAN
Malicious individuals mainly use “global IP addresses” to
gain a foothold for attack. The longer the same global IP
address is used, the higher the probability of unauthorized
access to the LAN.
When using a fixed IP address service, or using a network
that keeps using a dynamic address assigned upon
connection with the Internet, we recommend that you
configure adequate security settings.
You should also give heed to the
password setting
Using the product without setting a password will pose
a great risk for security. Be sure to set the password, and
change it periodically.
