Intrusion/Attack Detection

If the same IP address is accessed more than the specified number of times during a certain period, access from that IP

address is prohibited. In addition, IP addresses for which access is prohibited are managed as a reception refusal list,

and the reception refusal status is released (deleted) with administrator authority.

The IP addresses subject to the rejection are recorded in the audit log and sent to E-mail alert address lists 1 and 2 and

E-mail alert dealer address list.
