SETTING MODE►SYSTEM SETTINGS MAC Address Filter Settings This option sets a MAC address. It allows access to the machine from the MAC address you set. Intrusion/Attack Detection This section explains how to protect the machine by partially blocking communications with an attempt to attack the machine via network. If the multifunction device receives more than the set number of communications from the same IP address within the set period, communication from that IP address is prohibited. IP addresses whose communication is prohibited are recorded in the audit log and registered as a reception refusal list. In addition, those IP addresses are notified by e-mail to the addresses in the e-mail alert message list 1/2 and dealer e-mail alert message list. The removal of the IP address from the rejection list is also recorded in the audit log. The maximum number of IP addresses that can be registered in the reception rejection list is 100, and when the number reaches 100, external connection requests for multifunction devices will not be accepted. Factory default settings: Disable • Even if the power is turned on/off, the intrusion/attack detection settings and reception refusal list are retained. When you execute [Reset the NIC] or [Factory Reset], the intrusion / attack detection settings and reception rejection list are initialized. • When you want to send e-mail to the E-mail alert address list or E-mail alert dealer address list, enable [Security Alert] in [E-mail Alert]. When the first attempt of attacking the machine is made, the attacker's IP address is registered on the list of denied IP addresses. IP address xxx.xxx.xxx.1 List of Denied IP Addresses xxx.xxx.xxx.1 Since the attacker's IP address is on the list of denied IP addresses, their attack does not reach the machine. 9-177
