Network Security
Recent years have seen an increase in attacks on systems by computer viruses
and in data falsification or leaks by hacking, resulting in more serious damage.
Infection by computer viruses not only affects your own system unit (victim) but
also might inflict damage on the unspecified number of targets through networks
(victimizer). In most cases, it is often said that inflection is caused by careless
downloading of data or use of data media of unknown origin. Effective means to
prevent infection include installation of anti-virus software or firewall for blocking
illegal access.
We recommend introducing preventive means simultaneously whenever a
network connection is established. Also, security can be maintained by keeping
the anti-virus software up-to-date. However, this does not mean that the
anti-virus software can always prevent infection with computer viruses. It
becomes important to establish and operate a system to prevent infection with
such viruses.
System scan

Periodically check if computer viruses are hidden. It is convenient to use
anti-virus software's scheduling function that enables automatic scanning
periodically.
Downloading the latest date

It is essential to always update anti-virus software in order to address
computer viruses that evolve on a daily basis. A virus pattern file and the
version of anti-virus software are included as the data to be updated. No
computer viruses can be found or eliminated if neither the pattern file nor the
software version responds to the virus invaded. We recommend establishing
an environment where your anti-virus software can be updated automatically
and periodically. See the manual that comes with your anti-virus software for
more details on how to use the anti-virus software.
Windows update check
If Microsoft Windows operating system (OS) is in use, Microsoft Corporation has
released an additional program to fix errors or vulnerability of its Windows OS.
Please visit the Windows Update website to confirm and install update programs
periodically.
Windows Update Website：

Windows Update is also accessible from your Windows start menu.
Some computer viruses send their own copies one after another to a
connected network. If your computer is infected, we recommend
disconnecting your LAN cable immediately and isolating the computer
from the network in order to prevent secondary infection.
