about them. It helps enhance security by configuring a filter that can block suspicious transmission
sources and applications based on the detected information.

NOTE
• 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
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.
• This function can apply to each interface.
• Using this function decreases the speed of
accessing the Internet, etc.
