Configuring the intrusion
detection function
In the "Configure unauthorized access detection", you can
set the direction of packets to be detected and the processing
method upon detection, for each PP (provider or other
external connection) or LAN (LAN connection) interface.
Note
The intrusion detection function can apply to each interface and
I/O, but the larger number of applications may decrease the speed
of accessing the Internet, etc.
For more details on the settings, click "Help" on the setup
screen and refer to the description displayed.
To open the "Configure unauthorized access
detection" screen
From "Basic configuration page", click the buttons on the
setup screen in the following order:
▶ "Advanced settings" in the top page
▶ "Configure" of "Configure firewall"
▶ "Configure" of "Illegal access detection" of the interface
of which intrusion detection function settings you want
to change.
Checking the history of
illegal access detection
The history of illegal access detection can be checked in
the "Intrusion detection information" field of the "Generate
report on system information" screen.
Note
• The "Intrusion detection information" field of the "Generate
report on system information" screen is displayed only when
the illegal access detection is enabled.
• Note that new unauthorized access methods and intrusion/
attack patterns are constantly being discovered and thus no
completely infallible prevention method exists. We would
like you to understand that not all of unauthorized accesses
can be detected by this function.
• As this function detects accesses that are similar to intrusions/
attack patterns, some unauthorized accesses may not be
detected due to timing or a range of other reasons. On the
other hand, a detected pattern does not automatically mean that
a serious unauthorized access has occurred. Please understand
this and use this function only as a guide for your security
management.
To open the "Generate report on system
information" screen
From "Basic configuration page", click the buttons on the
setup screen in the following order:
▶ "Advanced settings" in the top page
▶ "Execute" of "Generate report on system information"
